Hackaday "Jolly Wrencher" 1.5mm x 1.5mm

The output is now finished. This is Hackaday's "Jolly Wrencher" or a reasonable facsimile thereof. Took 1.5 hrs to plot out, one pixel at a time. The logo is 1.5mm on a side, 50 pixels per. Might well be the largest thing RepRapMicron has done so far, though I'm yet to test out the full 4mm x 4mm theoretical workspace.

So the "Maus" RepRapMicron mechanism still works, and the electrochemically etched nichrome tip that I bent stood up to it all. That's a relief. I could deposit at much finer resolution in resin as I can get down to 15-20μm per pixel with that rather than the rather ragged 30μm pixels that the mechanical process of chipping away Sharpie marker creates. Not so visible for debugging but.

Still, this PNG to GCODE converter works well enough. Might be a convenient way of testing the conductive/semiconductive resins for arrays of LEDs or sensors etc. when I finally get hold of some.

Here's the Maus in the process of doing the print. I'm using the mechanism described here and Arduino/GRBL electronics.
