Arduino CNC Shield v3 Engraving Machine/3D Printer/A4988 driver GRBL compatible
- Coolant enable
- Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825, and others) (Not Included)
- 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.)
- Please note that this is an unassembled kit and needs soldering.
- Latest Arduino CNC Shield Version 3.10
- GRBL 0.9 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)
- 2 x End stops for each axis (6 in total)
