This little driver runs on a RPi V 3B+ and is connected to a PCB board to control the steppers.
Until now, a gamepad is required to move the head around and select and start programs.
A Web UI is available on http://:1506
Eagle drawings and cam files are available in the folder PCB (TODO). Reach me out, I still have some PCBs on stock.
