Barton Dring designed and built a Polar Coaster drawing machine to draw custom, round drink coasters:

I recently decided to update the Polar Coaster project. The primary reason was to update the controller to use Grbl_ESP32 firmware. I also thought I could make it smaller, lighter and remove a little cost.
The old controller was not custom made and just sort of tacked onto the back. This increased the size and didn’t look very good. It had a Bluetooth module, but you still had to stream the gcode. You could use an Android app, but that was still a little awkward.
The controller runs Grbl_ESP32. This was recently updated to include pen machine features. This allows precise control and calibration of the pen servo. You can control the speed, timing and endpoints of the servo travel.
