Description

CNC Shield Board:

• Latest CNC Shield Version 3.0 for Arduino.
• GRBL 0.9 compatible. (Open source firmware that runs on an UNO for Arduino 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)
• 2 x End stops for each axis (6 in total)
• Coolant enable
• Uses removable A4988 or DRV8825 compatible stepper drivers
• Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to  1/32 micro-stepping )
• 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.)
