. It is designed as a shield and can plug on top of an Arduino requiring no external connections and wiring. Controlling each step stepper motor requires only two IO pins on the Arduino.



  • GRBL 0.9 compatible.(Open source firmware that runs on an arduino UNO that turns G-code commands into stepper signal
  • Uses removable A4988 compatible stepper drivers.(A4988,DRV8825 and others)
  • PWM Spindle and direction pins
  • Axis support(X,Y,Z,A-can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3
  • 2x End stops for each axis (6 in total)+one probe
  • Coolant enable output
  • Jumpers to set the micro stepping for the stepper drivers.(Some drivers like the DRV8825 can do up to 1/ micro-stepping
