The Arduino CNC Shield makes it easy to get your CNC projects up and running in a few hours. It uses opensource firmware on Arduino to control 4 stepper motors using 4 A4988 Stepper drivers,
NOTE that the CNC Shield PCB you receive would be RED and the Crowduino & A4988 stepper drivers in the picture not included.
Features
GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals https://github.com/grbl/grbl)
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)
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.
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.)
