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.

    How do you keep the pen tips vertical position accurate as it pens around without something dragging in the drawings?

      I’m not perfectly sure I understand your question, but if you see it in action, this thing is really wobbly. Not much precision there.

        I was basically just asking how wobbly it is, haha.
