This CNC 3D printer Shield V3 A4988 as a driver expansion board can be used for engraving machines, 3D printers. It is a total of four slots, can drive four A4988 or DRV8825 stepper motor driver, 4-axis Arduino CNC Shield v3. Each road stepper motors only need two IO ports. Very convenient to use.

Specifications:

1. Latest Arduino CNC Shield Version 3.10
2. GRBL 0.9 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
3. PWM Spindle and direction pins
4. 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)
5. 2 x End stops for each axis (6 in total)

Features

1. Coolant enable
2. Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825, and others) (Not Included)
3. Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
4. Compact design.
5. Runs on 12-36V DC.
6. * * * Jumpers color may vary depending on the available stock.
