Uno CNC Shield Arduino Project Kit

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
