Finally, something is moving on the R2.

The gear is taken from Media Conversions, I took the basic dxf file, imported it into Fusion 360, extruded it, and chopped it up using a jigsaw type connection so each piece would fit on my print bed. So far I’m very happy with the result.

I’m powering it right now with a small 12V DC power adapter intended for use with LED strips. However it may be underpowered, the Arduino seems to reset after continuous use. The DC motor may be pulling too many amps.
