I managed to get a repeatable, automated probe etch done for the #RepRapMicron #3Dprinter, using the Z axis to control the etch. These are 0.3mm diameter 316 stainless wires, etched on different occasions. Yes the probe walls are meant to be rough to hold the resin "ink":

Took me a while to figure out I could use the #RepRapMicron #3Dprinter to etch its own probes. This is a test of my wee electrolysis cell. You can just see the turbulence caused by electrolysis when the probe dips in.

Okay, I feel I can put the PIKA #RepRapMicron files up on Printables and let the world loose on it https://www.printables.com/model/1692745-reprapmicron-pika-micron-resolution-3d-printer

Phew! Managed to get the PIKA #RepRapMicron assembly docs done. Well, started, here come the revisions...

Oh yeah, #RepRapMicron PIKA V0.01 levelled a 1mm square bed to within 4μm!

I had an idea for a print-in-place XY Table (basically a #3Dprinter print bed or stage) for the #RepRapMicron. So what the heck, here it is Fediverse

Green bit is the bed. Hollow grey boxes would have solid walls but you wouldn't be able to see anything.

Just finished printing the bits for the next gen #RepRapMicron. In black. Immediately, Lewis The Massive Hairy Ragdoll leaps up onto the bench and moults all over it. His fluff is white, which of course is magically attracted to black objects...

Preparing for the first Geeko Farm livestream, running alongside Jon Oxer's #RepRapMicron build on SuperHouse to take notes and offer help if he tears out his hair... Oh.

Charging headphones, check. Studio mic, check. Notepad, check. Folding screen to hide all the crap, check. Tea mug filled with scotch, check.

New laptop still pending though, so AV is going to be running/crawling on USB 2.0 😬

Jon Oxer of SuperHouse spoke with me at #EverythingOpen about doing a livestream of him building a #RepRapMicron #3Dprinter. Well, it's this Sunday NZ/Aus time: https://www.youtube.com/live/9y5YsKGFets

Boy is the documentation wiki due for a shakedown!

I shall lurk in the background.

Jon Oxer is going to livestream a #RepRapMicron build on his SuperHouse YT channel.

I feel a great distubance in The Force, as if many documentation fixes suddenly updated at once...

The nice #EverythingOpen peeps have put a video of the #RepRapMicron #3Dprinter presentation up on the youtubes https://youtu.be/dq_ZCf0-KmM

Yay! #EverythingOpen presentation runs on Linux and Windows - my ancient Linux laptop has no HDMI so I have to borrow The Boss'. Also got Windows controlling the #RepRapMicron, so might bring that along...

Prototype micro-gripper for #RepRapMicron (13x scale model)

http://blog.reprap.org/2026/01/kinky-probe-gripping-things-and-new.html

Tried burnishing some Dutch Guilding down to see how conductive it is. Answer: Not.

Looked at it under the microscope for clues. Well thar's yer problem.

#RepRapMicron

Microscope slide gimbal. Couldn't find one so designed one. The point of a binocular #microscope is to view and manipulate in 3D, so you really need 3doF to position the sample.

Latest #RepRapMicron piece. A folded and fastened structure with a hair threaded through it. The squares are 0.8mm across. The sides are two print lines wide, 30-odd layers thick.

#3Dprinter

Figured out that each dot of resin the #RepRapMicron #3Dprinter puts down is about a billionth of a ml.

Here's a picture of a millionth of a ml of resin squares stuck together at not even close to a right angle. They're 400μm (0.4mm) on a side and it's untidy and hairy because I did it manually and "spilt" resin everywhere during manipulation. Made a total pig's ear of it, but shows the potential for making foldable structures and setting them in place. The structure will support a pin.

Here's a short 400μm diameter cylinder (viewed from above, probably about 40μm thick) with a 12μm thick base. I printed it on the #RepRapMicron #3Dprinter, accidentally flooded the slide with about 20-30μm of resin, cured it, and peeled it off. This preserved the fragile base that you can see inside the cylinder. I was actually trying to clean the slide for reuse...

The big pointy thing in the background is a 0.5mm diameter hypodermic needle poked underneath the resin.

Looking for commercial tools to take my printed parts in the 10-200 micron range and assemble them to within a micron, as part of #RepRapMicron research.

Guess what? Nobody makes them. WTF? Ones that work 10-200 nanometres, yes. Microns no. Oh, and they start at US$17,000.

Oh well, was planning on making my own anyway...
