I believe this was caused by the horrendous layer adhesion of this silk PLA. Didn't have time to tune the filament, and based it off of another silk one.

This is clearly just AI slop, but I had to share it with someone.

The bowden tube between the extruder and hotend somehow got unscrewed, and the extruder just kept unspooling filament around the room, as the printer kept happily going on.

Here's a photo from farther out:

I upgraded two Prusa MK3s to MK3.9, and ended up with a couple of spare boards, stepper motors and a bunch of other things. So I decided to turn them into a Makelangelo clone!

Since the school I work at had these large standing whiteboards, I designed and printed corner brackets to hold the motors, as well as a base for the electronics.

I'm still having trouble with the homing process, but very happy with the results so far!

I'll be posting the firmware and 3d printed files online soon.

J'avais pris cette photo en avril, je me suis dit que ça pourrait faire sourire quelqu'un.
