19.0035.00

This shield is designed to allow you to control a CNC router or milling machine from an Arduino board. It contains 4 driver sockets which allows compatible Pololu A4988 driver modules to be inserted providing the ability to drive 3 stepper motor axis (X, Y, and Z) plus an optional 4th auxiliary motor. Additional connectors provide easy connection of end stop sensors and control buttons.

Description

UNO for Arduino———————- expansion board

  • 8 ———————— EN (stepper motor driver enable active low)
  • 7 ———————– Z.DIR (Z -axis direction control)
  • 6 ———————– Y.DIR (Y -axis direction control)
  • 5 ———————– X.DIR (X -axis direction control)
  • 4 ———————- Z.STEP (Z -axis stepper control)
  • 3 ———————- Y.STEP (Y -axis stepper control)
  • 2 ———————- X.STEP (X -axis stepper control)

Features

  • GRBL 0.8c compatible. (Open-source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
  • 4-Axis support (XYZA-Can duplicate XYZ or do a full 4th axis with custom firmware using pins D12 and D13)
  • 2 x End stops for each axis (each axis pair shared by same IO pin)
  • Spindle enable and direction connection.
  • Coolant enable connection.
  • Uses removable Pololu A4988 compatible stepper drivers, e.g. A4988DRV8825 and others (not included)
  • Jumpers’ headers to set the Micro-Stepping for the stepper drivers.
  • Compact design.
  • Stepper Motors can be connected with 4 pin dupont/molex connectors.
  • Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
