New X/Y 0.9 stepperzz are here!



Now how to connect them to the ender5?

I was thinking to cut a JST-XH 4 pin 24AWG extension cable (5,50 Euro a pop  )



for Lipos and solder the two ends, one to the motor one to the E5.

Please tell me there is a better solution.

EDIT: Yes there is
JST SM 4pin, much better IMHO cheaper and with mechanical secure latch.

I'm having fun with mine too.  Tiny Toothless is 28mm tall.

Nice beast, one day I will go below 0.2mm Z layer too, but first I have to design custom plates for the dual Z upgrade on my E5.
Oh the 0.9 steppers are coming today, ohhhh another upgrade.

Thanks. Lots of Sharpie touchup, but he'll be a kewl custom token for Monopoly night. 

I'll be honest... I didn't expect much after shrinking the model down to ~25% of original, then printing at that layer height. But the TMC2208 micro-steps evidently isn't all hooey even on a Single-Z, and if I'd remembered to turn ironing off would've been much better... that probably obliterated like the top 5 layers on his ears.

Been playing with an interesting plug-in for Octoprint called Arc Welder, read more here  -

Arc Welder

"Arc Welder attempts to replace G0/G1 (linear move) GCodes with G2/G3 (arc move) GCodes. This can substantially compress many GCode files, and may reduce stuttering caused by sending many tiny movements in rapid succession over a slower serial connection. "

So far I've tested Arc Welder on several models and I can't detect any difference in their quality comparing prints before & after being processed, but the file has less commands and thus prints a little faster. I attached a screen shot of the Arc Welder processing report for one model I created for a project I'm working on - road transition between model railroad tracks.

Interesting but my spider senses are telling me that apart less gcode, as you said and touched with your hands, there will be no printing quality improvement.
...you still have a X and Y stepper not a new nozzle rotation stepper which is triggered by G2 G3.
stuttering? Go for dual Z or something mechanical. For mechanical sickness the best cure is always a mechanical therapy, not a SOFTware one.

Anyway related to that I deactivated G2/G3 Arc Support, it save memory on my tight ass melzi board and AFAIK no slicers SW support arc anyway.

Another intersting fact I read is that slicers eat only lines and points not arcs, so computing properly arc G-Code is a big PITA for the slicer software. I think on Firmware/Octoprint level is the same music.

[xrunner]

Oh I didn't have any stuttering at all (my machine  ), I just wanted to test it for the file size compression. As long as the model comes out the same it's good for me.

Currently abusing myself with Frustion360; working on a insert to organize all my favorite drivers in this little SS box. In theory they should all go; in practice...

LOL.

The wee people asked me "What's holding up their world?", and I told them "A turtle."

They asked "Well what holds up the turtle?"

I told them "Another turtle you nitwits!"

You just made the most concise, incisive analogy for religion I've seen in at least a decade.

Well done.

Currently printing at 20% infill and 0.28 LH. It's like watching firehose laid down after printing Tiny Toothless.

Still a 17 hour print.

It looks like a menacing array of rocket launcher tubes. 

All these road transitions were done in F360 as well as this last piece. But what I wanted to show is, sometimes the surface quality of 3D prints turns out to be useful in surprising ways.

I printed this one upside-down and had supports under the ramp (underneath the top slab it is cut out to save materials). I lightly sanded most of the part anyway so the surface would not be so smooth and so it would take paint better. Then I realized I had a cool effect that I didn't plan for, and exactly in the right place. It was caused by the print supports. I set out to sand it down more but realized I was looking at a desirable effect.

It looks just like those no-slip ridges put in concrete roads, and it ended up in the right place - the ramp! I stopped sanding that area because it looks perfect like that. I love these kind of surprises.

I am now with Octoprint on a shiny FreeBSD 12.1

even an idiot like me has done it! 

[Zucca]

Temped now to go for KDE and setup a little FreeBSD Octoprint laptop station for my E5, the old Lenovo Yoga I am using has touch screen it could be a winner.

Maybe one day.

EDIT: I am very lucky, just installed the 12.1

After seeing this video, I just updated my Marlin firmware (to version 1.1.9.1) to enable Mesh Bed Leveling.

Sure but, look at here

AUTO_BED_LEVELING_UBL (recommended) combines the features of 3-point, linear, bilinear, and mesh leveling. As with bilinear leveling, the mesh data generated by UBL is used to adjust Z height across the bed using bilinear interpolation. An LCD controller is currently required.
MESH_BED_LEVELING provides a custom G29 command to measure the bed height at several grid points using a piece of paper or feeler gauge. See G29 for MBL for the full procedure. This type of leveling is only compatible with PROBE_MANUALLY.

Moreover according to here, the auto bed leveling can be used also in manual mode by activating the PROBE_MANUALLY.

I think as soon I get home I will activate AUTO_BED_LEVELING_UBL with PROBE_MANUALLY

Ehhh.... A mixed bag. I had misgivings when I previewed it in Cura; I could see I'd been a bit too aggressive with the the middle row of holes, and Cura exaggerated the gaps in the slicing process. But I REALLY wanted to get more of my favorite drivers in there, so I decided to see how it would work out.

Overall it's quite serviceable; I did get the 8 jeweler's drivers and the 6 large ones I most needed in there. A couple of the holes drag a little when putting/pulling a driver, and the divider with the smallest cross-section snapped out first time I put a driver in. We'll see how it continues to serve; I may have to revisit the design and shrink most of the holes in the center area so that all the other slots are properly supported.

Well done, now you should stick a little dragon on the side.

when I switch to AUTO_BED_LEVELING_UBL with PROBE_MANUALLY no go....

I see you've never stuck your hand awkwardly in the cutlery basket of a dishwasher and had a fork tine stuck deep under a fingernail.

I will never, ever store my tools pointy bits up or towards myself; my coordination means it only becomes a miniature impalement device.

The scalpels in particular make my old wounds ache.

Easy to see what the tools are, when stored like that.  -  I have mine lying flat in a tray, as a compromise!

I know but >12% memory for that feature, no thanks I keep my MESH and done.

Sure; I can definitely see why having the bit end up is useful.  It is just my stabby-stabby sausage fingers that would impale themselves automagically.  (Although I have about a dozen visible scars on my hands, I still have all fingies and full mobility and no nerve damage.  Only by pure luck, though.)

That said, I do like having a simple thick shelf with holes, so you can drop the drivers from above through the hole, and see the pokey bit below the shelf.  For a desk holder, that'd make it shaped like a 9 or a c with a thicker top, though, and I don't know if it'd work as well.  The handles tend to weigh a bit, so a desk holder of that design would be terribly tippy.
