Features:- The extension board can be used for Small CNC routers, Carving Machine, 3D Printers, DIY Laser Cutters, and almost any project where you need to control a stepper motors with high precision This shield allows you to control upto 4 stepper motors Controller each stepper motor requires 2 IO Pins only, which saves a lot of IO Pins for other purposes Arduino compatible 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) Supports 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) Supports Coolant enable Supports removable 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 DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.) Uses removable A4988 or DRV8825 compatible stepping driver.
