CNC shield v3 engraving machine 3D Printer + 4pcs A4988 driver expansion board
Engraver CNC Shield Board
- Size(L*W*H):68 x 53 x 18 mm
- Voltage:DC 12~36 V (At the moment only the DRV8825 drivers can
- Handle up to 36V so please consider the operation voltage when powering the board.
Features of Engraver CNC Shield Board:
- Uses removable A4988(provided) or DRV8825(not provided) compatible stepper drivers.
- The extension board can be used for carving machine, 3d printer driver expansion board
- GRBL 0.8 compatible. (Open source firmware that runs on an for 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)
- Compact design. Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
