Description:

CNC Shield V2.0 can be used as a driver expansion board for engraving machines. It has in total 3 channel slots for A4988 stepper motor driver modules (not included) for driving 3 channel of stepper motors. Each channel of stepper motor only needs 2 IO ports, which means 6 IO ports is sufficient to manage 3 stepper motors. This shield can make quick work for managing stepper motors in your project.
Specifications:
GRBL 0.8c compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
3-Axis support (X, Y, Z , )
2 x End stops for each axis (6 in total)
Spindle enable and direction
Coolant enable
Uses removable 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 microstepping )
Compact design.
Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
Runs on 12V DC.
