The MicroMill is driven by an Arduino UNO (clone) with a Protoneer CNC shield from Protoneer (Ebay). The board is equipped with 3 Stepstick stepper drivers. Only the Z-axis driver has a cooler installed.
Connected are:
- Power supply on Blue screw terminal
- Green button to Resume
- Red button to Abort
- Door to E-Stop
- Yellow wire to SpnEn (single wire on white pin)
- Red/Black wire to 5V/GND (between Blue screw terminal and reset)
- 3 stepper motors (X, Y, Z) to 4-pin connectors next to stepper drivers
