Using an Arduino to make a CNC miller !

The RepRap Arduino-compatible MEGA Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino-compatible Mega with the powerful Arduino-compatible MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino-compatible MEGA shield for easy service, part replacement, upgrade-ability and expansion.

Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.

Note: A4988 motor driver boards are NOT included in the package.



  • CNC Shield compatible with Arduino MEGA
  • Control four stepper motors with A4988 stepper drivers (driver board not included)
  • One motor can clone one of the other motors
  • GRBL compatible pinout
  • Can be interfaced with other microcontroller systems
