Eccentric Workshop GRBLDuino Mega Shield V1 - 6 Axis GRBL v1.1 Arduino CNC Controller Shield

GRBLDuino Mega Shield is the first user-friendly GRBL v1.1 compatible 6 axis Arduino Uno CNC controller shield for homemade CNC routers, mills, and other builds. Similar to Protoneer CNC Shield and perfect for Mostly Printed CNC builds (MPCNC).

Offered in assembled or kit form. Kits require soldering of standard through hole components and takes approximately 1 hour to assemble.

Features:
  • Fits Arduino Mega 2560 (not included)
  • Designed for Pololu DRV8825 stepper motor drivers (not included)
  • Works with power supplies up to 45 volts DC
  • Screw terminals for all machine control connections
  • Double end stop terminals for each X, Y, and Z axis (does NOT support auto-squaring)
  • Single end stop terminals for each A, B, and C axis
  • High or low activation limit switches/end stops
  • Emergency stop, abort, door safety, hold, and resume connections
  • Spindle speed (PWM), enable, and direction connections
  • Flood and mist coolant connections
  • Probe connection
  • 6 independent axis capability - can also clone 3 axes
  • Full microstepping control for each axis
  • Genuine Nichicon capacitors


To have a complete CNC machine, you also need:

  • 1 control computer (to send G code to GRBL)
  • 1 Arduino Mega running GRBL v1.1
  • 1 stepper motor driver per axis (pin compatible with Pololu DRV8825)
  • 1 stepper motor per axis
  • 1 stepper motor power supply (max 45v DC)
  • 1 spindle, pen, laser, drag knife
  • 1 CNC machine structure
