Designed to help build a small CNC router or CNC milling machine, Arduino CNC shield kit (Arduino Extension Board) offer you a big help, Features: 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.)  * * * Jumpers color may vary depending on the available stock.
