ARDUINO CNC SHIELD V3

ARDUINO CNC SHIELD V3

د.ا 12.00

  • 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. (A4988DRV8825 and others) see our module HCMODU0068
  • 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.)

Description

Description:

This shield (HCARDU0086) 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 (see HCMODU0068 on our website) providing the ability to drive 3 stepper motor axis (XY& Z) plus an optional 4th auxiliary motor. Additional connectors provide easy connection of end stop sensors and control buttons.

Schematic and test Sketch available on our support forum.
