Daily Notes

I heated a pellet of polycaprolactone (soft thermoplastic) and stuck it to my 3D printer hotend with tweezers.
I then held a small industrial diamond (there were plenty of loose ones in a pack of rock carving bits I bough recently) beneeath it and pressed it up into the still-soft plastic.
Then I had codex whip up a UI to control the printer via the octoprint API.
I can now scribe tiny patterns into a glass microscope slide, to steer crystal growth. First tests cooling + evaporating now :)
