Title: Fusion 360 - MECHANICAL design Tips Tweaks and discussion. (Not Eagle)
Post by: beanflying on May 30, 2020, 07:57:46 am
A place to hangout and discuss ask questions on how to do X in Fusion 360 from a Mechanical or CAD/CAM perspective.

Not a place to muddy it with bitching about Eagle Beta or Autodesk anti propaganda. Do that elsewhere!

A few useful Youtubers on Fusion 360

https://www.youtube.com/channel/UCo29kn3d9ziFUZGZ50VKvWA (https://www.youtube.com/channel/UCo29kn3d9ziFUZGZ50VKvWA) Lars works for Autodesk but these now older videos are still worth a watch in particular the Basics ones.

https://www.youtube.com/user/TheKHaug (https://www.youtube.com/user/TheKHaug) Kevin Kennedy is a NON Autodesk and has come to Fusion from other software. Recommended for newbies in particular.

https://www.youtube.com/channel/UCU7QDqWAeIdCK5aNFXPgX2g (https://www.youtube.com/channel/UCU7QDqWAeIdCK5aNFXPgX2g) Fusion 360 School. Lots of great snappy tutorials and a heap to be learned.

https://www.youtube.com/channel/UCLEVULiWognkczOpDSGSlFg/videos (https://www.youtube.com/channel/UCLEVULiWognkczOpDSGSlFg/videos) Also a Fusion employee but these are his and he now runs some of the Autodesk live streams.

https://www.youtube.com/user/AutodeskFusion360 (https://www.youtube.com/user/AutodeskFusion360) The Evil empires own Channel and they have been running more consistently over the last few months in particular.

Some of the 3D printing Channels I follow do some good content from time to time on specifics.

Also worth a look

https://www.youtube.com/nyccnc (https://www.youtube.com/nyccnc) New Your CNC. Primarily a CNC workshop but some good Fusion 360 CAD and in particular CAM videos.

https://www.youtube.com/channel/UCxgunnLdsV72eAezHW6u0KA/videos (https://www.youtube.com/channel/UCxgunnLdsV72eAezHW6u0KA/videos) Fusion with a mainly 3D printing content and some Laser use.

https://www.youtube.com/channel/UCeKpbMimEGgLM_0tnghfoVw/videos (https://www.youtube.com/channel/UCeKpbMimEGgLM_0tnghfoVw/videos) Mix of CNC, Fusion and some 3D printing.

Install it watch a few Beginners youtube tutorials and have a bash it costs $0 to play  >:D

I went looking for a more graphical method of producing a Laser Cutter wiring diagram for non Electronics nerds to follow. Tried Fritzing briefly [attachimg=1] looked at a few others and couldn't find what I wanted so I have been experimenting with a 3D approach. The other obvious approach would be Inkscape etc and do it as a 2D graphical option but this way the model can be made available online and be manipulated for viewing or working with it without installing Fusion.

The Stepper and attached wiring was where I started. Brought in the Nema 17 from McMaster-Carr then rather than adding a connector started a simple sketch. Extrude a few mm of fake wire, extrude a six core sheath and few mm of fake wire then use the loft command to link them together. The plan is this Stepper and 'Stub' will form the component to be used in a larger model.

To do a cable run then all you need to do is create a simple 3D single line path and follow it to where you need to go. Colour coding sheath or no sheath or dropping back to four wire is easy and can be done in the larger model.

The Model is over here if anyone wants to play https://a360.co/3c0vm2w

Hi,
I am new to Fusion 360. I got interested to support my 3D printing activities.

I have learned a lot by watching Clough42 on YouTube. Here is an example:

https://www.youtube.com/watch?v=Hd_x2jSgz9A (https://www.youtube.com/watch?v=Hd_x2jSgz9A)

He use the features of Fusion 360 to solve some real world problems.

I have created so 3D models for KiCAD:

It was been a bit of a haul for me as any real CAD usages was Ancient Autocad 2 I was taught at Uni on a HP Mini System with terminals (look it up it makes me the other side of 50  ;D)

Todays expansion of the Stepper idea was to Scratch up the Driver part of it. Not an Engineering model by any means but a practical simplified version for the purpose I have planned. The Screen printing from the original went under the flat bed scanner and was placed on the Face as a 'Decal' (cosmetic and no thickness) in Fusion. I haven't completed the stub connector part yet.

Model is over here if anyone want to play further https://a360.co/2AozrQQ

Not that it matters to me but I will insert the Steppers into my current Laser build 'just because' they will exist 8) 100W Laser shown here with the rear panel removed four grey boxes for the upgrade. Lots of detail lacking in the model such as V-Slots and fittings but this enables me to check fit of parts and provide a cut list for the sections and panels.

As for AutoCAD, I was a user at version 2 also... also it dates me.

I like the spirit of accurate models of bought parts. So often, you can get a "3d representation" from the original mfg, but these are usually devoid of nuance. Yours is very accurate, this takes patience. The font is usually the most difficult to represent. But, what I do when I create these models, I store as a "library" part that I can quickly slap into an assembly later. However, with staples such as power supplies, these change so much nowadays and you may never find the same model/mfg again the next time.

With that said, "Is it worth the extra effort?". It depends on time constraints.

Nice work.

Just needed to say... I'm sick of Fusion (https://www.eevblog.com/forum/index.php?action=dlattach;topic=81471.0;attach=779856;image) me every time I try to do text on ANYTHING.  |O   That said... at least it's not Eagle. *shudder*

I DO like how easy it is to think in "extrusions" with Fusion; they make it easy to design a "silhouette" of the core body of an object correctly situated on the correct planes and just pull it out to the desired height/length.  :-+

Agreed Text currently SUCKS on Fusion BUT during a recent live stream I hit up Brad about it and they are working on a fairly major long overdue upgrade of the Text functionality. https://forums.autodesk.com/t5/fusion-360-feedback-hub/feedback-on-upcoming-text/td-p/9537505

The biggest issue with Text as it is currently  is the bounding box not being fully defined meaning the text can be bumped stretched or just plain go wrong if that isn't done properly  |O In the workflow I leave the text until nearly last then generally but not always define it so it doesn't go kaboom.

Last things in the workflow are generally Fillets and Champhers as changing the model proper after these often breaks them. If I want to change the model I roll the timeline back before these helps minimise the breakages. This took me a long time to learn and lots of  |O

Oh Hells yes... proportional text box, text on arc and kerning are ALL things desperately needed. As well as a "simple" mode where you just start a text box, enter your text, then click on a surface to apply it; THEN, once you see what it's going to do, adjust font, size, +/- depth, +/- pitch and +/- slant of italics.  :scared:

Yeah, I also discovered that getting the main shape done and saving the fillets, then text for last was a major lifesaver; as well as making sure to save a new revision before doing fillets or text. That way if you revise something then go down a different design path, you don't have to worry about going back far enough to accidentally undo fixing a borked plane or something and finding it AFTER you've already done fillets & text.  |O

I've noticed that I get a lot more pushback from Fusion when trying to do multiple fillets at once, even on a single face; often it just goes NO!!! NO!!! NO!!! and I have to do most of them one covalent angle/line at a time. But a LOT LESS often does it break planes in the process, making 1-sided walls that have to be patched later (if possible at all) before it can be turned into a single body.

I've also noticed that whatever mechanism it uses to "auto-patch" a mass into one body after extrusion actions is a lot better; you can get a lot more complex in your angles without it randomly deleting or breaking individual polys and giving you voids to patch later. You know, until the exact instant you come to COUNT on it.  :-DD

Okay... Here's a basic design question for those with the know-how: I want to make a sandwich-type control panel box out of 2 300 x 400mm sheets of acrylic with 13mm radius rounded corners; I bought a stack of them cheap for this purpose. Normally, I'd just sketch out a couple concentric rectangles describing those dimensions and the inner dimensions, then extrude that to the desired height, then do my fillets to match the corners.

Here's where it gets sticky: I want the top panel to angle downwards such that the front wall is ~45mm high and the back is ~85mm high. This object will then have the corners filleted, incorporate built-in hinges for the bottom panel, then finally be sectioned into 4 workable sized pieces for printing.

What's the best way to start...? A trapezoidal sketch with the correct profile to match the size of the panels, extruded horizontally into a solid? Then how do I make uniformly thick walls after extruding the center cavity out of the solid?

I've played with the "rotate on" function, but I don't want the front/back walls to have a radius; I need them flat as there may be an I/O plate involved.

Hi,
Can you share your F3D file?

I am not sure exactly what you want to achieve. I have the front and back surfaces vertical.

Here is my version:

[attachimg=5]

and the sections through this model

[attachimg=2]

If you download the attached file, you can use these controls to step through how I created this. It is not to scale.

mnementh,

If I draw two sheets 300 x 400mm with 13mm radius corners. I have placed one horizontal and one at 15 degrees.

Are you looking for a box that will hold the panels in this position with a uniform wall thickness?

Try this.

I used the loft and shell modifications and then punched out the bottom with an extrude.

I have attached the F3D file.

Sometimes problems are best approached sideways  ;)

Draw your side parallelogram but don't try and draw it accurately or think about it to much let Fusions parallel, symmetry and mid point functions to do the brain work. It can be done bottom up but it is really messy and would need offset planes and lofts  :--

** Note I set the HEIGHTS of the Nodes at 45 and 85 and not the length of the line connecting the upper and lower lines **

Sketch 1 is not fully defined but can be by several methods. Placing the construction line tied to the mid points of your upper and lower allows the upper 'fixed length' line to move and retain the heights already defined so it would be easy to make front and rear slope in equally if that suits. The more simple version would be to simply make the front or rear face vertical using the single constraint depending if you want the slight slope at the front or rear.

Then Three extrudes, Left Face, Front and Back Faces & Right Side. Add fillets etc as needed.

Damn you and your tricksy little constraints straight to hell, bean!!!  :-DD

Ahhhh... okay. So I WAS on the right track; I created the above objects by sketching a parallelogram, but then I extruded it as a single body. What I need to do is create the front/back walls as well in the sketch, that way the shapes of all the walls are defined.  :palm:

I’ll spend some time tomorrow looking into those functions; I must admit the way you were able to manipulate the entire construct is quite enticing... thank you!

Okies... next question... I usually leave fillets till the last... as much as I want to just get jamming on something semi-finished looking, I think I need to figure out sectioning and bottom hinge first.

I figure dividing into quarters with overlapping fingers should be the simple solution, and if I do it right I can incorporate the hinge into the seam at the back of the box. I intend to sink button magnets in the bottom wall opposite the hinge to make things dead easy.

I’ve seen some really neat videos on things like hinges and latches using the animation workspace, but really not ready for that yet. If you know some good beginner vids on that type of construction in the design workspace, please point me there.

Cheers,

I ran into a similar issue with the 740B control box I made some time ago as the sides slope in on the original and in all sorts of wacky angles and I did my  |O then  :-DD

So as it is a cold and wintry day out there I moved this upcoming project up the list as the guts of it was done and sitting in Fusion ;) Will be 3D printed sidewalls with Brass Inserts to retain the top and bottom Laser cut panels. Still need to finalise how much real estate I need for the low voltage switches and an Ammeter but as shown here 180x300 but I will slim it down to maybe 280 and print face down as 1 piece on the CR-10. Tweaking the dimensions of the box is trivial and shouldn't break anything else as it is all fully dimensioned.

Some of the alternates put up have some severe limitations on abilities and some insist you publish ALL your designs as open source on the 'free tier'. So when looking at a package bear that in mind.

Trying to be even minded about it Fusion and it's two current 'free tiers' offers most of us an amazing package for $0 BUT at the whim of the Evil Empire that might change but the community backlash would be truly epic. Such is the nature of Cloud based software.

urrgh. Frustion360 is (https://www.eevblog.com/forum/index.php?action=dlattach;topic=81471.0;attach=779856;image) me again; this time trying to draw the rectangle to define the inset for the panel. It'll create the workplane where it should, but instead of drawing ON THE WORKPLANE, it randomly picks some height BELOW the workplane & draws the rectangle THERE.  :wtf:

[EDIT]   Okay... I outwitted the program that is SUPPOSED to be helping me make an object.  ::)   By reorienting so that my POV is from WITHIN the body of the object, I was able to FORCE FuckWithMyHead360 to start ON the workplane.  :wtf: is the point of defining a workplane, when it is just going to start drawing wherever the fuck it feels like anyways...?  :rant:

Yeah, I couldn’t figure out how to get it to show the timeline; maybe they have that disabled as the new licensing takes away “collaborative” features on the hobbyist/free version.

That is exactly how I created the main body; I got through that relatively painlessly.  :P

The problem was it being a dick with the “create sketch” function on existing surfaces. I’d click the face I wanted to draw on, click “create sketch”, and it would create the workplane right where it should.  But then when I started to plop down points to make a line or rectangle it kept selecting everywhere BUT the damned workplane and just put the damn thing wherever the fuck it felt like, usually some random depth below the workplane. |O

Between that and the way it randomly fades the quadrille away to the point you can barely see it; like I said... my balls are just achin’.

I notice you seem to have the origin showing so I wonder if that was getting selected rather than the face? If another sketch is showing the create new sketch can also trigger of it rather than the face.

Yeah, okay... except that is the EXPRESS PURPOSE of defining a workplane in ANY CAD program I've ever used otherwise. You do this to tell the program EXACTLY where you want to work. I think this core stupidity is also part of what is Oh, so fucked-up with the Text functions; something fundamental in the software's architecture that PREVENTS these core functions from working the way most CAD programs work. :-//

I dunno... is that the price of the otherwise easy-to-use yet powerful nature of the application...? Or is it really too much to ask that they adhere to SOME common-sense rules used by the rest of the industry...?

The 3D sketch functionality in it's current form is new (l1-2 months I think) and I haven't seen any video on it or have I looked that hard either or played with it.

Re the Origin on or off or used or not. I use it initially to set a general point in space and direction to the model then it goes off. From that point forward ALL other planes, sketches and surfaces are referenced off the model. One of the most powerful sides of Fusion is having one change upstream change the entire model because of this referencing. If you keep referring back to the origin you are referencing the beginning to my way of thinking not the timeline concept that Fusion works on.

It's been sectioned, all holes are "drilled" where they should be, and shockingly, no children were killed in the making thereof. The joints are all relieved by .2mm to allow for 3DP tolerances per the advice of one of the yoobtoob vids I watched; turns out it was the "thicken sketch" operation as part of the sectioning process which he recommended that was causing the unexplained error.  :-//

All that remains now is to countersink all the segment assembly screw holes holes and do fillets and I should be able to start fab; might even get something printing tonight. *knocks on wood*

So it turns out Fusion does have a Bug with Decals and inserting derived models - So Reported and in their system  :-+

HOWEVER - according to Phil @ Fusion I should be inserting 'Linked Models' not using the 'Insert Derive' in this case. Why was I not aware of this because it is not an item on the insert menu :wtf:

[attachimg=1]

It is done by using their file system and right clicking and selecting 'insert into current design'. This works great if you want to insert the entire model in that link but it lacks the flexibility of the 'insert derive' where you can insert a bit from another model.

So a solution sort of and onward  |O

So I finally broke down and installed Fusion after spending multiple days writing a new threads library for openscad from scratch.  It works well and renders much, much faster than other libraries, but it was a PIA directly calculating every point and facet in the thing to maintain standard thread profile and whatnot in order to get the perf gain...  But I digress.   I'm familiar with thingiverse for getting various stls and scad files.  I usually spin my own designs from scratch anyway, but not when I'm just getting started with a new-to-me software platform.

Any recommended sites for open source/free Fusion designs files?  Especially if the site is primarily for 3DP audience.  Thanks

There are some I have shared in the https://www.eevblog.com/forum/chat/3d-printer-yet/ (https://www.eevblog.com/forum/chat/3d-printer-yet/) thread but given the size of some Fusion files I have tended more toward just uploading STL's there. Some things I do are really niche so I don't share them and some of what I do is for $ and nothing to do with Electronics so they don't always get shown.

As to a larger Fusion sharing site there isn't one I am aware of and as the software is aimed at commercial use it is more likely you will only find files linked to here or there rather than a library.

Here is an early project box of mine if you want something to play with. Takes generic 7x9cm evilbay project boards and 3mm knurlnut inserts https://a360.co/2MANwxq (https://a360.co/2MANwxq) Bound to be some things in it I would do much differently now but it prints great without supports.

Thank you for sharing your Fusion 360 file for the box.

I put the box together:

It looks like there is no gap between the lid and the body of the box?

I see you printed this, how does the lid fit?

I generated the STL file for the box and sliced it. The software estimates 3.5 hours to print the box, no lid. How long did the print take?

As the saying goes 'I like a tight Seal'  >:D It worked fine as is with my CR-10S at the time and I have done a couple of the Ender which also worked. If you are worried about it use the press/pull (Q shortcut) and push the mating face in by 0.1-0.2mm to give it some clearance. Print time sounds about right too.

Hi,

This is my version of the 7x9 project box:

[attachimg=1]

The modelling is different. This is the order of operations:

Modelled the PCB first.
Encased the board in a solid block
Applied fillets to the external corners
Used the shell command to hollow the block
Split the hollow block
Add the lip around the lid
Add mounting spacers

Still to do

Add the lid attach.

IF you change the board dimensions or move the mounting holes on the board, the enclosure will 'track'.

File attached.

Not sure which thread is better for this Q, this topic or the 3D Printer Yet? one.  Figured "Mechanical Design" might be a closer match.  ANYway...

So I'm working on a few different projects related to 3D printable pneumatic parts and/or piped air kinda stuff.  My immediate project I'm trying to get done is an anemometer (air flow and pressure meter) that uses a couple reasonably precise I2C pressure sensors (BMP388's).  I have an initial prototype that kinda works, but I still have much experimenting to do with different pitot/venturi/etc configurations, and hopefully improve sensor drift a bit.

But the issue I keep coming back to is how to run wires through the wall of a pressurized 3D printed container/pipe?  For a finished design, using gasketted nuts and bolts as intermediate conductors would probably work, but not ideal when I'm trying out a bunch of different configurations and need to swap the sensors to newly printed parts.  Using glue to fill in around wires run through actual holes in the container doesn't really work since the sensor modules I'm currently using have little cable adapters that I don't want to mess up. 

Thoughts?

Without a bit more of a picture of what you are doing I would have thought surface roughness and 3D printing would be an issue? What sort of pressure are you running at?

Back when I had a real job we used fairly much off the shelf Stainless Cable glands with submersible pumps at a few Bar of water pressure with open motors in the shells under them. Against a pressurized container they should cope with a bit more providing you don't blow the threads out.

The cable glands should provide a good short term solution.  Long term too unless I figure a different way of doing it that is printable.  Thanks!

Yea, surface roughness, getting air-tight connections with non ideal tolerances and octagon-ish "circular" curves makes things a bit challenging trying to do pneumatic bits and pieces with 3DP.  To start with, I'm using pressures not much above ambient, but I'll see what I can get up to.  When (if?) I come up with designs worth releasing, I fully intend on doing failure testing...  Who needs fireworks when you have designs to test?  Perhaps those little printed plastic pinatas are filled with unicorns?   >:D  Heh.  Kidding!  (Mostly...)

If you can lay your hands on an old CPAP/BiPAP machine, particularly the ResMed series (I've picked up a few at the thrift) to tinker with, they have a pretty well developed differential pressure venturi & MAF sensor assembly in them which tinkery might lend some valuable insight into the work you're doing.

@beanflying:  I'll probably play with your switch later.  I'm currently debating taking the plunge into CNC and laser cutting.  To be clear, the cheap-but-better-than-a-toy end of the spectrum.  I haven't done either before, so my dilemma is figuring out the cheapest solution that isn't a waste of money...  I don't think I'm ready for a complete-from-scratch DIY reprap type setup, so I've been looking at chinese kits (with ball screw) and such.  Your microswitch and muppet comments reminded me that I need to look into endstops.  Heh.

How long did it take you to make the microswitch model?

If you can lay your hands on an old CPAP/BiPAP machine, particularly the ResMed series (I've picked up a few at the thrift) to tinker with, they have a pretty well developed differential pressure venturi & MAF sensor assembly in them which tinkery might lend some valuable insight into the work you're doing.
Heh, funny you should mention that.  I actually have a CPAP machine in the room, but it's on loan and the way it's manufactured is not friendly to uninvited tinkering.  I'll check the local thrift joints when they finally open up.  I was thinking of just doing an airflow meter, but your mention of MAF made me scratch my head a bit....  Hmmm...

How about using a small PCB with the connections soldered and an O ring (or silicone):
Yea, that could probably work for lower pressures.  I'll probably try that out as soon as I figure out what I'm doing for non-o-ring gaskets.  Which brings me back to my current ridiculous excuse -- ERR -- I mean my current "need" for cheap-ish laser cutting in my lab.  I have multiple sets of cutting tools, but no, of course I want sharks with laser beams mounted on their heads.  Or unicorns with lasers?  I'm not sure if that's a more appropriate reference for this thread.

Probably 30 minutes I guess for the switch model. It wasn't important to be to uber accurate with things like measuring arm angles etc but it is accurate on the rest if it needs to be made into another assembly for example including the mounting holes and width. So model appropriately I guess is what I am saying, in some cases I would simply leave a space for the switch in the design rather than model it and insert it.

With Laser cutting or CNC for that matter think seriously about what is the biggest likely wiget I will want to make 'sometimes' or if it is a one off or very rare you need a big widget then look at the differential between out sourcing the work to extra size and cost of owning the bigger toys and the space requirement.

Initially I went for an upmarket 300x200 40W Laser and should have gone to at least a 600x400 60-80W in hindsight but I am now building a 1200x900 100W :-DD In reality this is larger than needed for all likely jobs but it is the last Laser I will need or build (famous last words  :palm:).

The larger CNC I own and still need to get rewired and operational (separate dirty workspace reasons partly) is a 1000x600 working area with a 2.2kW spindle, which while not huge if I need anything larger done I would be happy at this stage to farm out as the next step up is really to a full 8x4' bed and the space required is massive. I could generate work and $ locally if I owned a larger one but it is not where I am currently at.

EDIT - Virtually wired in place

With Laser cutting or CNC for that matter think seriously about what is the biggest likely wiget I will want to make 'sometimes' or if it is a one off or very rare you need a big widget then look at the differential between out sourcing the work to extra size and cost of owning the bigger toys and the space requirement.

Initially I went for an upmarket 300x200 40W Laser and should have gone to at least a 600x400 60-80W in hindsight but I am now building a 1200x900 100W :-DD In reality this is larger than needed for all likely jobs but it is the last Laser I will need or build (famous last words  :palm:).

The larger CNC I own and still need to get rewired and operational (separate dirty workspace reasons partly) is a 1000x600 working area with a 2.2kW spindle, which while not huge if I need anything larger done I would be happy at this stage to farm out as the next step up is really to a full 8x4' bed and the space required is massive. I could generate work and $ locally if I owned a larger one but it is not where I am currently at.
[attachimg=1]
Hmm.  Well, I have the challenge of finding an "apartment friendly" solution that avoids being lynched by my neighbors, plus all the normal challenges getting into CNC and laser for the first time.  I have plenty of available windows, so fume extraction should not be a problem, and I'll probably have to use a tarp/drop cloth to catch dust and debris, and supersize my mini fire extinguisher.  Is CO2 commonly used to keep work pieces from catching fire?  Working area size-wise for spindle use, the baby 3018 kits are too small but the 6040 kits are a bit too expensive for me ATM.  For laser, it would be nice to have a larger format but cheap frame big enough to cut reasonably sized colored acrylic panels for a dry box and 3DP enclosure.  I'm still scratching my head on this one: you can get away with a large cheap belt driven frame for laser, but using the same kinetics and controller for both the spindle and laser saves a lot of cash...

For spindle:  What wattage/RPM should I get for PCB work and/or non-metal enclosures, or generally speaking milling/cutting/drilling materials up to but NOT including metal?  I'm arbitrarily using surface mount and through hole PCBs as my minimum capability bar.  As far as noise pollution is concerned (apartment...), how much of a difference is a water cooled spindle compared to air cooled?
For laser:  I really, really, really, REALLY want a higher powered CO2 or equivalent laser, but that just isn't going to happen any time soon unless there is an extremely good fire sale, so I'm looking at cheap-ish chinese laser modules.  Any idea what the minimum output wattage laser module would be that isn't a complete waste of money, for cutting colored acrylic on the upper end of use (and rubber or silicone gaskets)?

I'm sure I'll have questions more related to Fusion after new toys -- ERR -- I mean tools get ordered and delivered.

I make no apologies for puddles of drool but I also acknowledge there is always someone out there with a better, faster or bigger toy/tool too in an ideal world I would have an 8x4 table with a Big spindle and Plasma fitted :-DD

With your apartment limitation and your current wants there is a couple of options. One is you build a 'proper' CNC router with linear guide rails and ballscrews because open build rollers and belts will SUCK for accuracy in particular if you want to do SMD sized PCB's. 400-750W of VFD spindle will be plenty (avoid using woodworking router adaptions). IF you are prepared to not do any large or photo engraving then you 'could' fit a proper real 10W diode to the gantry for cutting and slower speed engraving this with a few passes will do 3mm Acrylic and leave you with one machine. Given the complexities of CO2 Lasers/Mirrors and lenses it is really not compatible with the mess of CNC in one box.

If you choose the better option of the two a separate Laser given the space constraints then 40W is sensible you can cut slowly 6mm Acrylic/Ply in single passes and run high speed engraving. My current Toy - https://www.eevblog.com/forum/reviews/40w-300x200mm-laser-cutter-engraver-vollerun/ (https://www.eevblog.com/forum/reviews/40w-300x200mm-laser-cutter-engraver-vollerun/) but with a bigger capacity than mine is sensible. X axis Linear Bearing and Y with roller wheels and belt drive on all is fine as there is very low inertia compared to CNC Routing and the Y movements are slow compared to the X. One option is DIY from Rob who I got the plans for my bigger one then bashed to larger ones again well worth the few $ for the Fusion Plans and build guides https://www.furtherfabrication.com/resources?category=Y400 (https://www.furtherfabrication.com/resources?category=Y400) this size and table top style makes sense and his videos are worth a watch regardless https://www.youtube.com/channel/UCZ72zDm2feverqV7qAbNH7Q (https://www.youtube.com/channel/UCZ72zDm2feverqV7qAbNH7Q)

Only one BRB may be shown but I think the size of my upcoming build will maybe get one fitted at each end.

Another 'rough' model for the project today. Take the picture use it as a Canvas and use the apparent known over all dimensions for scale. Result sort of kind of looks like the real thing and good enough for 'stralia and then added into the job ;D

Yeah; that's exactly what I was thinking on the BRB thing; one of my regular clients back in the day required a BRB at eye-level (even if it had to be mounted on a pole) on every left corner of any machine or series of machines & jigs bigger than a refrigerator. Point being you ALWAYS knew where to look for it no matter where you were or what side you were facing.

What's the duty cycle on that compressor in this application...? Is it one recommended by the people who made your LASER or its driver...?

Asking because that particular one just OOZES "Cheap China-Direct POS" even from a picture on the computer screen... LOL  :-DD

The nozzle requirements are really low at only a few PSI and a few LPM so the vibe pumps do fine and are more or less standard with most Lasers. For mine I might just run it via a regulator/trap off my small tanked compressor but  :-// it won't make a lot of difference as the extractor is the noisy bit.

I'd like to lodge a complaint against the Bea-nNut Gallery...  I previously had myself convinced that I'd just go with the cheapest laser diode module that had enough power not to be a complete waste of money.  Now after binge watching Rob's DIY CO2 videos and buying and reviewing his build plans, not nearly as complicated as I had previously envisioned...

And it seems quite a bit cheaper than I had thought too, at least if you avoid commercial electronics and go the reprap/Marlin/blah route for control and stepper drivers...  He listed cost of aluminum extrusion at around $500 for the large format (1200mm x 600mm working area) and around $300 for his smaller desktop design (600mm x 400mm working area), so scaling the thing up or down doesn't change the overall price a whole helluva lot since Rob's BOM includes about the same $ for electronics as the laser+laser PS...

Hmm... 
Maybe your next design should be a drool cup with ear-loops...?  ;)

That sounds ergonomically challenging, a bit too curvy for my current CAD skill level, but I'll keep it in mind.  Or I could just re-purpose an old fashioned tin-can-and-string telephone.

This morning over Coffee I went looking for a model for a USB Drive to insert. NIL found :-//

So what I did find was some very boring one piece cable end models https://autodesk-fusion.partcommunity.com/3d-cad-models/sso/usb-cables-te-connectivity?info=teconnectivity%2Fcable_assemblies%2Fcopper_cable_assemblies_new%2Fmultimedia_cables%2Fusb_cables.prj&cwid=6550 and split their boring grey selves into bits for some adaption and material changes.

Then copied the tweaked USB A bits into a new Component and roughed in a body styled after Brand V without the retraction bit for a KISS Drive. All three are here if they are useful https://a360.co/3hdA00S

EDIT: RJ45 model is here https://a360.co/2XUD0HP I treated it fairly differently to get the 'look' I wanted. Rather than split it up I just changed a bunch of surface finishes to Blue and Clear but it remains one body.

The Raised Text is actually done in the larger model with one face coloured for visuals so you won't find it in the model linked above.

'Fixed' also redid the Pneumatic Plumbing layout. Added another lump to the design I wasn't going to. The Industrial blower because they are clunky looking and would dominate the layout. The Cure is change it to Clear Acrylic as a material and add it in. There to show what it is but see through so it more or less hides.

Learn to love the Loft Command.

Shiny Bling. 3/8 Thermistor thingy so the Render is just because.  >:D

Single Sketch as shown. Three Extrudes, one for the hole in the brass plug, one for the body and another for the two connections. Loft one Body to one connection as a new body then another for the other side then use the combine bodies command to put them together.

The Brass bits and Hose ends are all inserted from manufactures and just put into place using the point to point move so the alignment is easy.

Just for completeness sake Epic model is now complete.  https://a360.co/2XZg1u0

Some of the details

17 Discrete Externally created custom models linked into the design (some of them then used multiple times) plus about 6 small Models created in the larger model.
Maybe 20-30 externally sourced models/components from various libraries are used within the various models.
Something over 150 Sketches
Having a quick look at some of the sections and there is well over 1000 bodies in the overall model.

Ryzen 3700X 32GB and a 5700XT Cruises fairly much. The GPU numbers peak around 40% if you really spin the model around, memory usage is fairly light peaking at about 8Gb. That all changes when you try an in-canvas (local) render all cores pegged and very light GPU load >:D

The online viewer also has some good features you can right click on bits and hide them or also add markups and export views.

Interesting... So loft in this case is being used as a "mirror" function? That does sound like a powerful function. *makes mental note to search out some tutorials*

The brass tee and the plug you used as a base for the TC are all from someone's catalog; McMaster-Carr or Grainger, etc... you only had to make the silvery bit? That is intended to represent a stainless tube, crimped around a couple wires, like most industrial thermocouples/thermistors come packaged?

 I wouldn't have thought of that; I'd still be (https://www.eevblog.com/forum/index.php?action=dlattach;topic=81471.0;attach=693381;image) trying to make the brass plug. :clap:

You could use the Mirror command with one loft but you would need a plane to mirror around or you could copy and rotate the part around an axis but then you need to create that axis. So Two Lofts then post joined into one is easiest in this case. More ways than one to skin that Cat ;)

The Tee and Plug were McMaster Carr bits using the Move command but the align point to point in this case. Get the orientation correct first then pick a circle on one and a circle on the other and tweak the height if you need to. It took me some fiddle the first few times but do it in that order makes it easiest.

EDIT: There you go todays learning module  >:D Place the Tee under the plug after fixing the orientation of it. Use the already created sketch and make the 4mm Probe and pins with lofts. 20mm Probe and 5mm pins with a 5mm offset is about right for the look. Download link https://a360.co/2N3vJiM

Got to look after the Kids and your mental health first  :-+

The move is two parts in this case as I deliberately laid the tee on its side (Because I am >:D)
Step one is just a rotate as per pic one.
Step two is put the tee and align it with the plug/ This is what took some sorting out for me initially. I tried just using the 3D move arrows to align bits and they never did. You just need to pick in this case two circles and it doesn't matter they are different sizes Fusion will force a common center point. For looks I then moved the Tee down 1mm so a partial thread shows.

This small skill is really worth learning and in particular the point to point move.

Then onto the sketchy extrudy lofty bits.....

In a similar vein this concept model https://a360.co/2N9BaNb for Cross Bed Airflow on a Laser.

The Elbows were made using a Loft between two Plates. This could have been done with a Circle on one sketch and a Path on another with the Path function but the Loft is easier. ** For those who haven't tried the Loft function it will not Loft a hollow object it needs to be a solid surface.

So When your Loft is done use the Shell command to hollow it out. But this leaves an issue of the far Face still being in the model. Select it and do an extrude cut to remove it from the world and then you are done.

Take this base model use the rectangular pattern on it do some rotations and aligned moves and presto you have a model to get a concept across to others.

I got this email, too, and figured that too many people were taking advantage of the free service for it to be worth Autodesk's while.

The only part of it that is aggravating is that it won't do STEP export any more.

The "10 active and editable documents" thing seems to me to be that you simply indicate (somehow) that a document is "inactive," meaning that it can't be worked on or edited. But it's still in your cloud account. If you need to work on it, make something else inactive and re-activate it. For the home user who just wants to design things for 3D printing it's not much of a concern.

I wasn't so sure. I saw another bit of content on their site somewhere earlier today where they indicated that you need to "archive" a project to let yourself make a new 10th one.

When I took a project in my account and started to archive it, you get a dialog with this scary-sounding warning:

Since it was just a sample project, I then archived it, went to the website and restored it, and it does appear that you can still work on it once restored.

I also use F360 to create STEP models for Kicad. A thing I did last week was to create a 3D model of the rotary encoder with RGB LED shaft that SparkFun sells. It's a close fit to the Bourns part (same PCB footprint) but the body size is different enough to not be a true replacement. Bourns has a model, Sparkfun does not. And I was able to create a decent-enough model of the part and I put it into my Kicad library. I didn't bother re-generating the STEP model of the PCB with the new model; instead I just modified the board model that I had already imported into F360 and replaced the Bourns model with mine. That worked as expected.

The guy who does the excellent Kicad Step-Up thing (which, for those who don't know, is a tool that takes a STEP model and allows you to precisely place it within the PCB footprint) does that with FreeCAD. But FreeCAD is shite compared to F360. I guess you get what you pay for, dunno.

It's not just KiCAD. I used it for making step files for Orcad and Altium as well. This is a super big deal to me. I guess I've got to look for alternatives, as this functionality is not worth $300/year to me.
UPDATE - I googled around a bit and found this: https://www.alibre.com/atom3d/ (https://www.alibre.com/atom3d/) Looks like a promising option, no-BS permanent license model, and upgrade path. Will need to take a closer look at it.

Stick a fork in me, I'm done.

yeh, with their claims of "staying true to our guiding principles of democratizing design for everyone." it just doesn't feel right that someone
using every day professionally and some using for fun as a hobby on weekends should pay the same

to a company using it professionally to make money $800 for three years might as well be nothing, for a hobbyist not so much

I'm not happy about the loss of STEP export either, but I take the perspective that I, as a weekend hobbyist, am going to continue to use Fusion360 for modeling for 3D printing and I'm not going to pay the same as someone using it everyday professionally.

They're going to pay $300-450/yr and I'm going to pay nothing.

It's taken you this long to figure that?

It's Autodesk. They're not in the business of giving people free stuff - their core is to sell expensive stuff. The only reason they let you have this for nowt is because that's the only way to get new bums on seats. It's a well-trodden path, particularly with complex products where there is a learning curve - get them hooked with low- or zero-cost versions and then force them to upgrade once they are locked in. Microsoft achieved this by turning a blind eye to pirated Word, so despite stuff like Ami being superior they got the eyeballs. When a business buts new stuff, what their users already know has the foot in the door, and the rest is history.

Here, they want your muscle memory to favour their tools, and all your documents locked into their format. The longer you stick with them the harder it will be to break away...

The surprise here is not that Autodesk are turning the screws but that apparently no-one saw it coming.

To all who is/was using Fusion 360 for creating KiCAD footprints : you should definitely try FreeCAD.

It has much less features than Fusion 360, it is also harder to master and has some issues.

But from the other side - it has got some plugins dedicated to exchange data between KiCAD and FreeCAD. You can send your models back and forth in just a second. It also has a one button click funtionality to importPCB model from KiCAD so you can easily fit it to your housing modeled in FreeCAD.

I have tried FreeCAD -- for the Kicad Step-Up -- and other than for that one specific use, FreeCAD is awful.

But is actually free, and will remain so :)

As it happens, I used it for real last night to create a 3D model to print. My normal CAD tool is TurboCAD, so FreeCAD isn't as bad in comparison than if I were coming from Fusion. But then you pays your money and takes your choice - if you like Fusion 360 enough, surely you would buy a license.

We all saw it coming. We're not stupid; we're engineers FFS.   :P

But there's a difference between "turning the screws" and making your introductory product useless for its primary purpose, thereby driving those who might be willing to give you money for it turn away in disgust. AutoDouche aren't just stepping over that line, they're moving the line to the edge of a cliff and jumping over it. ::)

Given what it has to offer now I certainly wouldn't give them more than $50 for it, and "Not only no, but hell NO!" to their moronic subscription-only business model. :palm:

I'll continue using the free version to make plastic toys and spacers/cribbing blocks/bushings to print on my 3DP; that's exactly what it's good for. Any further drafting work will be done in some other environment, and I will take the skills I learned on F360 elsewhere, giving AD $0 for that education. That's exactly what their business model is worth.

Well, see, that's the crazy thing. All over this forum I see engineers (or maybe they're hobbyists pretending to be engineers) who are always looking for ways to "hack" a product to get a "free" upgrade (see the endless Rigol and Siglent threads) or looking for cheap clones of products. "Oh, the Saelae logic analyzer is too expensive, fuck them, I'll use the clone." So if you're an engineer, you should understand how product pricing works and why the Saelae is more expensive.

I wonder how many of these engineers expect customers to pay their asking price for their products.

I wonder how many of these engineers decry Chinese cloners when it comes to their products.

To be honest, I'm surprised that their free version has persisted as long as it has. How does a company pay its engineers if a very usable version of its product is free?

Sure, it's just "software," and "software wants to be free," but unless you work for free and don't want anyone to pay you for your designs, then surely you see that software development is not just handwaving and magic. It's real work.

Please report back and say which environment you've chosen, and whether it's as efficient as F360 or as easy to learn and use, and we'll all switch to it en masse and show those fuckers at Autodesk that we think they suck!

I mean -- yeah, I use Kicad and it's an excellent piece of work regardless of its cost. I hope that their Kicad Services thing enables the developers to make a living doing it. I started using it several years ago (during the run-up to the 4.0 release) because I needed to design some boards and my Ultiboard license was showing its age. Altium then as now was way more expensive than I could justify. The only real option was EAGLE. And I looked at EAGLE, and considered springing the $1000 or whatever for the unlimited license, but hot damn that program was a mess. The libraries system stinks, the user interface was designed by dingbats and the only reason it ever got any traction was because they had a very limited free version that all of the Open Source Hardware weenies jumped on. (I should note that I looked at gEDA back then and that package sucks in every way.) To be fair, the recent price drop in OrCAD makes that look attractive, but see, Kicad is eminently usable.

Can FreeCAD become to 3D design what Kicad is to PCB design? Sure, yeah, if the developers had vision. And income. Right now, FreeCAD is a toy, it has been a toy for several years now, and I don't see evidence that it will be anything but a toy.

All of this is to say that I'll probably end up springing the $300/yr for the "startup" or "personal" or whateverfuck version of F360. Why? Because it works.

All of these arguments were addressed in my "not offering a reasonably-priced personal-use/non-profit use version" comment.

What's broken in their business model is not that they expect to get paid for it, but rather that they deliberately design it to use lots of resources on their end, then use that as an excuse to try and sell it the way some corner pusher sells crack: Free at first to get you hooked, then out come the meathooks every few months for another chunk of money.

Not interested in propagating that business model. For my level of design, their thin-client approach serves ONLY them; it does me no favors. If they offered a sanely-priced version that just does what I need, I'd buy it... ONCE. Not gonna buy it over and over again.

Like I said; I'll use them as long as the free version continues to do what I need. I'll gladly take advantage of the education that software offers. When it ceases to do what I need, then AD will have outlived its usefulness to me and they will be kicked to the curb, just like Adobe and Norton before them.

Are we at Linux on the desktop yet?

Exactly.

But more to the point, it is obvious that there is a difference between OS development and a niche application like 3D modeling.

You might also notice that I mentioned being a Kicad user, and honestly, that's a better comparison than Linux. I think Kicad succeeds where gEDA and FreeCAD fail because the development process is clear and open, there's a vision for the product, there are a handful of serious lead programmers, and there is financial support from at least one large organization.

The subscription model gives them a steady income to keep the product current, at the extreme the alternative is that everyone buys it once and they close the company

That's rubbish. First, many many MANY companies seem to manage with a single charge per item. Particularly companies that have to actually supply stuff too (so have proper overheads rather than just a software duplication pseudo-charge).

Second, what God-given right do these companies have to be given a living? Why aren't I given a guaranteed income for doing a hell of a lot of work that no-one wants to pay for? If they want income they should supply what people want to pay for.

Manufacturers of physical goods employ designers to design new products. Unless you're selling tractors (apparently) you're not renting the stuff when you sell it. If you can't afford to continue development of your product because everyone that might ever buy one has already bought it, you suck as a businessman and should be doing something else. Running the UK government springs to mind, but there are other scenarios.

I'm particularly happy about subscriptions either but I understand why the companies do it, unlike a physical product unless there is a big change in computer hardware or OS, software doesn't "wear out"

just consider the subscription as a payment plan,

So you buy an oscilloscope. You give the vendor say $2,500. You have an oscilloscope, hopefully it does what you want. But what if you realize at some point that you need wider bandwidth, or more channels, or deeper memory?  Well, there you go, you have to buy a new oscilloscope. Well, ok, unless you bought one which has an option to add two new channels (which means you paid for an expansion capability you might never use) or add that bandwidth (by swapping out the front end boards with new ones, and you paid for that possibility up front too). In any case, if you want more later, you pay more later too.

re: overheads. So, software engineers don't get paid salaries and benefits? Their offices don't have heating, air conditioning, utilities, all of that? Or are you a hobbyist who thinks like Stallman that "all software should be free?"

They have none. But if they offer a product for sale, then what god-given right do you have to say that they charge too much or that you want it for free? Call up Autodesk and demand that they give you full-up F360 for free forever, and they'll politely tell you to go away.

People don't want to pay for someone else's work because they think they're special or they're entitled. You think you're entitled to their work for free because nobody wants to pay you for your work.

If they want income they should supply what people want to pay for.

They do. They supply a quality product at an extraordinarily low price. $300 a year for F360 is unbelievably inexpensive, compared to say a SolidWorks license.

Manufacturers of physical goods employ designers to design new products.

And software vendors employ designers and engineers to design new products, too. Again, you're laboring under the delusion that software engineering isn't actually work and that the engineers doing it do not deserve compensation for their labor. You seem like a manager. (Or a hobbyist.)

So how is it different from a hardware vendor making a new product with the income generated from sales of the previous product? If you're making a widget that nobody buys, you have no income, and you won't be able to make Widget Version 2. Same thing with software. The vendors take income from sales of previous products and plow it into development of the follow-on. If there is no income, there is no follow-on.

I think you're a hobbyist and you want everything for free because you're special. Ask whomever made the computer you used to post your rants if they'll just give it to you for free, because you're special. Please report back.

So consider why they are doing this. They could either demand $5,000 for the software, which would not be unreasonable, but it would put it out of the reach of hobbyists like yourself.

Or they could charge a lot less, like say $300 a year, and then as they say, "make it up in volume." Likely the choice to offer it for $300 a year means they think they'll actually make more money on the deal.

But what is obvious is that they were making $0 income on the free product. And in fact they were losing money on it, because it is very easy to get the personal-use license and then use the product professionally. They cut that off. As is their right. You don't like that because you're a cheapskate.

Running the UK government springs to mind, but there are other scenarios.

And I mentioned that there's no difference between software vendors and hardware manufacturers in this -- both employ engineers to design the new products. Both use income from previous sales to fund development of new products.

You are correct that there's no physical product distribution to deal with regarding software sales. So this gives the software vendor great leeway in deciding how to price their product. They can do what hardware vendors cannot -- make different versions of a product available at different price ranges and let a customer upgrade immediately to one with more features. You can't do that with a tractor, eh?

But there is still cost involved in the development, maintenance and support of a software product. Microsoft and Apple are always updating their operating systems (and Apple is always updating hardware), so there is great cost involved in just making sure an existing product runs on the latest operating systems. All too many software vendors give up on that. "You want support for the new OS? Buy our program again at full price." Or maybe they just never bother updating, abandoning it (like Xilinx ISE, but hey that's free) and then the customer needs to maintain old hardware and old OSes, which just puts more cost in terms of time and effort on the customer. Someone's always paying.

I know there are people on this forum who maintain old machines to run old software. Some of that is not by choice -- they have specialist hardware tied to old computers and new operating systems simply won't run the old software. A lot of it is by choice -- they don't want to re-buy the same software again. Or whatever.

So good luck on your future endeavors.

just consider the subscription as a payment plan,

It's not, since you can never pay it off. That's like infinite interest.

sure and in about 10 years you'll have paid almost as much as a license for solidworks

You complain that a product that used to be free no longer is. So clearly you want it to be free for you.

Actually, I expressed surprise that you lot didn't see it coming. Nowhere did I say I wanted this thing, never mind for free. I dare you to point out my post where I said or implied that.

Now kindly fuck off with your made-up insinuations and false attributions.

Or are you a hobbyist who thinks like Stallman that "all software should be free?"
Stallman does not object to companies or individuals charging for software. (He's not demanding "free as in beer".)
What he objects to is the lack of freedom as in "freedom of speech".

There is nothing in GPL to preclude charging for software or engineering. There is a lot in GPL to prevent the curtailing of freedom to modify and copy. (The latter has some implications on the practical ability to charge money initially, but those are in my experience [I did some work with/for rms/FSF briefly in college] very much secondary.)

...So you buy an oscilloscope. You give the vendor say $2,500. You have an oscilloscope, hopefully it does what you want. But what if you realize at some point that you need wider bandwidth, or more channels, or deeper memory?  Well, there you go, you have to buy a new oscilloscope. Well, ok, unless you bought one which has an option to add two new channels (which means you paid for an expansion capability you might never use) or add that bandwidth (by swapping out the front end boards with new ones, and you paid for that possibility up front too). In any case, if you want more later, you pay more later too.

I'm going to quote you out of context here; not to pick a fight but to point out that this is a REALLY bad choice for an example, as modern scopes (and SAs, AWGs, RF Gens... the list goes on and on) come with too much essential functionality that is enabled/disabled purely in firmware.

Then comes the inevitable argument over whether it's right, wrong, fair, immoral, offends the Tooth Fairy, etc if you hack said FW to enable stuff you didn't pay for.  :palm:

"sanely-priced consumer-level product" I'd say free with limitations that don't affect hobbyists much covers that.

if freeloading professionals are a abusing the free version instead of paying what is essentially  nothing compared to running a business,
I can see why autodesk has to do something

I'd say it doesn't, because that way the paying customers are also paying for the freeloaders, so the full license costs even more than it would otherwise, putting off more potential purchasers.

But surely Adobe have done the maths. Maybe they know that whatever it's priced at, even stupidly cheap, the majority of 'hobbyists' using it now still wouldn't buy a license.

I don't consider hobbyist freeloaders, the freeloaders are those who should buy a license for their business instead of abusing the free version

exactly, the hobbyist won't buy it anyway and without sufficient limitations on a free/cheap version some pros will just get that version whether the license allows it or not

Flagrant BUMP  >:D

Just entering my third 'free' year of Startup License as of Today. So if you have the creds for it worth getting this license to see if you like or dislike it before shelling out the $ in particular since some of the nobbling of the 'hobby' version happened. I was given the option to downgrade to Hobby as it expired and keep going too.

Todays Random Fusion 360 use. Quick Drill Template in paper. I have done them in the past as Laser cut ply or Acrylic for repeat use but this is a one off for a accessory panel in my Car. 10 minutes work drop some double sided tape on the back to help avoid any whoops moments  :palm:

One Sketch, extrude the bits I wanted and use the Drawing part of Fusion to print a 1:1 Template.

Fairly much. As the lip around the four main parts is fairly narrow being a few mm out with the holesaw points in particular would be a major cosmetic oops. I have done similar templates for IEC plugs and others I print direct onto my label printer for nibbling/drilling.

I really put it here as an idea of using 3D modelling software to produce a 2D result.

There you go you wannabe Canuck. And to others following along, sensible explanation of the 10 Doc limit for the Fusion Hobby License. Also check out some of his other content on Fusion 3d Printing and Laser use. I hadn't looked at it before but looks fairly simple to cope with unless you are a heavy using hobbyist.

Yeah, no... I've already had problems with projects mysteriously losing their complete history when I go back to them before this new indignity. I don't expect that to get any better once all my projects have been compressed & archived for long-term storage on their secondary servers.

I would so much rather store them locally, which I do export locally as much as possible anyways; now I will start doing it every time I make a new version of something so I can be sure I keep that history intact.

Today's semi useful Fusion tip learn to use and love the offset face function. Great for making clearances before manufacturing from Laser or 3DP. Not a strict Engineering job but a quick and dirty solution to fudge it into place.

Reason to do this is I twisted off the added BNC connector AGAIN  :palm: and this will stop it attracting cobwebs and as much dust in the shack or more likely its new home of my site bag. Good toy for a sanity check and this one runs within 10 Hz at 30Meg so not to shabby for the few $ and USB or 12V for power.

Rough physical model made first then offset the panels by 0.2mm from the PCB and adjust the tab clearances with the offset face function. Laser cutting tomorrow as it is Beer O'Clock.  :popcorn:

I will start a separate thread when I get to some construction but a little Jigging was todays Fusion for the first part of upgrading my 3018 Trash Router/Engraver in particular for PCB milling. I have been sitting on this Mobile phone repair clamp for way to long always with this in mind :-[ Aliexpress Seller I used (https://www.aliexpress.com/item/32470846617.html?spm=a2g0s.9042311.0.0.27424c4dUWUkHt)

Part of it's problem was always the flex in the supplied bed if you tried to clamp to it so I used to run heavy MDF then clamp to that which was a PITA. The base on this holder below is solid 6mm Aluminum so between it and the 5mm sacrificial MDF will lock the base up well.

One end of the four clamps has a 0.9mm deep rebate already cut into it and as they are 50mm wide plenty of area to provide even pressure on a PCB for routing. With adding a few extra holes and tapping them (eight) it will hold 10x20cm or 15x13cm boards fully supported and with some modified clamps on two edges a bit larger or more likely a different base but in reality larger boards are likely to be sent out and I would put up with the wait.

Shown is the sacrificial spoilboard that will get milled 'flatter' before use when attached to help get around some of the issue with PCB height variation. Also pre milling probing of the PCB surface via Flatcam. Spoilboards will get the Laser cutting treatment because I have one so nice and quick and accurate each time for hole locations.

Brushless motor and improved Z axis are the next and biggest bits to design.

So I have an upcoming job I want to electrically drive with a toothed belt. The plan is to use a Laser Cut Pulley out of Delrin but I might try one from Acrylic as I already have it in stock and the torque loads are fairly low.

So I went looking for how to model a GT2 (or 3) belt and there is a bit of a knowledge gap among the usual suspects listed in the opening post. I found this Youtube one below but his model breaks (likely due to a rounding/positional error) on higher teeth counts. Basically it generates teeth in space then tries and fails to stick them to a separately generated internal body.

https://www.youtube.com/watch?v=PDNIiLSTzG4 (https://www.youtube.com/watch?v=PDNIiLSTzG4)

I have had similar issues before with Fusion and circular patterns. The best solution is to first model the stock and then model the removal and pattern that feature. Feel free to play with both the one from the video above and mine here https://a360.co/357uhVM (https://a360.co/357uhVM) Mine does break the second Sketch occasionally but removing and reapplying two tangent constraints fixes it again  :-// Solve the problem and win a prize  ;)

The concept of 'Adequate Modelling'.

This model of a cheap 90 degree 10RPM drive is a model I ran up today. Omitted plenty of details like external gearcase screws and most of the rear motor detail as they simply are not useful or needed. Important bits are correct overall dimensions shaft details and mounting screw locations to fit into the larger project. Anything resembling a how to make the gearbox or motor would just be fluff and a time waster. KISS

Am I like the only one still having the file accessibility problem in the Free version? (Well, I assume it's somehow related to the fuckery involved with their recent "Editable/Read-Only" fuckerization of the database)  :-// I've updated twice since the shit hit the fan over this; and yes, I know the "workaround" is to reset the file type from "Editable" to "Read-Only" and back again... but any project made since then is simply not available if I've ever closed F360 on it. Everything I've been able to Google is the same old shit from back when the problem first arose.  ???

The fucking ring of doom just keeps circling forever and it never opens; I have to open the damned project on the web and import it. And shockingly, when I do that, the measurements are never exactly the same as what I created; they're always a few dozen or even a few hundred microns off. Seriously,  :wtf:  ...?

A Little while later and a small stash of 5mm Acetal sheet to Laser Cut into Rack and Pinions and the gearmotors have arrived in 10, 50 and 100 RPM. Just a quick mockup to play with on the bench before I get to a final design and intended use.

Acrylic to Acetal should be fine for side bearing/guides and 'reasonable' wear and Acetal to Acetal for the main working surfaces and the R&P. Price driven compromise as the Acetal is way more expensive than Acrylic. Talking maybe 1-200 operations a week at low frequency for the final application.

Linear speeds circa 8.6, 43 and 86mm/sec depending on Gearmotor

WAY WAY off the reservation of things E today. Fixture and welding table lash up for a good friend. Laser cut 12mm Aluminium (his number) tops at this stage but its a single click to pump them all to 16mm (my preference) then off to the Laser Cutter and a little post reaming and counterboring of the hold down points.

Reason for Aluminium is non stick to Slag or MIG spatter also non rust and lots of other good points unless you go Cast Iron.

Basic arrangement is make one panel then rectangular pattern for all the top plates, take that original copy it then spin in 90 degrees and move it to the vertical face and a second pattern. Basic frame is 75x50 and 75x25 heavy RHS.

The idea is sort of Fireball Tool meets 20,000km of separation in the Ozzie Bush.
