Arduino CNC Shield Kit
Build a CNC Router or Milling Machine
This Arduino Uno based kit allows you to build a CNC Router or a CNC Milling Machine.
CNC Shield Board:
- Latest Arduino CNC Shield Version 3.0
- GRBL 0.8 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
- PWM Spindle and direction pins
- 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
- Coolant enable
- Uses removable A4988 or DRV8825 compatible stepper drivers
- Compact design.
- Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
- Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
- Please note that this is an unassembled kit and Basic soldering skills are needed

Shield Kit ReviewBy: Patrick Egan on 5 July 2017I was happy with the purchase. I would like to have had some information regarding the hardware limits, ie voltage max for the drivers, the need for jumpers to set particular features.
CNC kitBy: dennis suitters on 31 May 2017You were correct, once I got my head around the basics I got my Nema 23s going on the bench. It took 2 days of reading, but got there, What a great product and thanks for your great service and help
