Arduino Cnc Shield V3 Engraving Machine A4988 Grbl Compatible 3D Printer

• Latest Arduino CNC Shield Version 3.03

• GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)

• 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) 

• Spindle enable and direction 

• Coolant enable 

• Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others) 

• 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 Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
