3D Printer yet?

[Brumby]

Sorry if I came across as dismissive to any safety related matters.  I am anything but.

The role of devils advocate is often an essential one - and that's in addition to offering aid based on experience.  I would consider withholding any advice on safety as negligence and culpability if anything were to go sour.



As for the extension of the concept to a cease and desist order ... that was meant purely as fun (in a sideways dig at our resident dwagon.)

[mnementh]

And it was taken exactly that way... don't worry. The dwagon's hide is thick; he can handle a little poking.

As for the Devil... he kicked me out for trying to take the place over.

I thought you were going with a 3-stepper arrangement...?

That price included the plate? Looks like 4-5mm thick... ~US$83... pretty reasonable considering the work involved. Hydro-cut? Did you tap the threads yourself?

If you have a Fiat 500 you can't turn it in a Ferrari, the best you can do is



68 Euro just the plate, total upgrade cost was about 100€.... I believe was laser cutter and normal CNC stuff...
No, I did not cut the threads myself.

[mnementh]

  Understood.

I meant did the ~US$83 include material, or was that just the labor. If he threaded the holes too, then def a good deal; usually as much time in that as the rest of the job put together.     Especially if a tap breaks, which is not uncommon with aluminum plate.

As for 3-steppers... I thought your plan was to have on the front one slider/rail in the center, two leadscrews at the corners, not t'other way around. That's also why I strongly suggested a sync belt.

Okay I am now 100% UBL 5x5 with no probe! I will never go back, it is fantastic!
The documentation on Marlin for an UBL with manual probing is not the best, bur with a little bit of patience I managed to get it up and running.
Problem you need a board that can handle >256KB of juice.

On other news:
I am now using the old magnet bed as a mouse pad.
I never felt a mouse flying under my hand like now! Why I did not put it under my mouse immediately after installing the glass bed?
whoooosh...

CR-6 auto-leveling just plain works. Even my Diggro is pretty close to zero assache since I replaced the crunky rollers on the Y-axis.

CR-6 auto-leveling just plain works.

Mine worked too, I just wanted to test the next level... UBL!
Is the CR-6 the one with a load cell? Oh yes it is.....

The idea is nice... but I think it is overkilling.... A shim gauge set will be my next toys for allignment, and then I call it done for ever.

[mnementh]

Naahhh... there are just too effing many variables involved in using measured current from a leadscrew/motor(s) as a bed sensor; too many places where a change in the inherent loading/friction of the setup can create an inaccurate reading, ultimately leading to a smashed glass or damaged polymer print surface. The engineer in me just shrieks at the idea of having the measurement device be part of the motor device; it's like having a PID loop programmed so the changing weight of the PID loop itself affects the self-calibration of the PID loop.

Enjoy at your own peril, he says.    The load cell in the hotend is the obvious choice, and it is so cheap. You can build the whole thing, bespoke design hotend and all for ~US$30. Only weakness is I dunno if it can handle the added weight of a DD extruder; that of course would be a matter of empirical design.

This will be the back leg for a 10" digital photo frame I picked up at the Thrift.

Getting better at Frustion360; I had a clear plan of how to make this from the start, including optimizing the design for flat printing. Total design time ~45 minutes. Currently printing at 0.20 LH, 40% Infill, Concentric pattern, 1.5mm wall/top/bottom thickness. We'll see how it works out; this is the first iteration based on my best guesses & rough measurements.

I prepared Explosive Runes this morning.

[Zucca]

I would like to see how much patience you will loose with FreeCAD. Personally if I can't save the project on my HDD... I go 
UUhhh "concentric pattern" I need to try that, did you choose it because that thing need to flex?

[mnementh]

I chose concentric for cosmetics and for the fact it builds the deposition mostly in the longitudinal direction, which makes it strongest in the correct plane.

      

This is the promise of home 3DP fulfilled; a few minutes designing, set the machine to work and go on aboot your business. Come back in a few hours and you have a complete, ready to use part waiting to be popped off the bed and put to use.

And now a digital picture frame that was destined to become eWaste becomes an extra Xmas prezzie to mom-in-law; one we know she'll love as it comes loaded with pics of us she hasn't seen.

Totally agree.  Action figures and Millenium Falcon models are fun, but the real benefit for 3D printing for people with some technical skills is making repair parts, making custom devices and the like with low input of personal time.  Telling the robot to go fabricate is far more appealing than a day of milling, filing, drilling and otherwise shaping.  And there is a lot of satisfaction out of recovering a previously unusable object.  Battery compartment covers alone are worth it, even though they are usually fairly challenging to 3D print.

This!
The majority of my 3dp projects are practical, replacements for broken parts, specialist parts or adapters that you cannot just buy, or improvements on existing designs.
