The Arduino CNC 3D Printer Shield V3 is developed specially for those beginners who are interested in CNC or 3D printers. This expansion board can be used for engraving machines and 3D printers. With a total of four slots, it can drive four A4988 stepper motors.

The Arduino CNC Shield makes it easy to get your CNC projects up and running in a few hours. It uses open-source firmware on the Arduino to control four stepper motors using four A4988 stepper drivers. With this shield and the Arduino, you can build all kinds of robotics or CNC projects, including CNC routers, laser cutters, and even pick and place machines.

Features:

• Compatible GRBL 0.8c compatible
• Spindle enable and direction
• Coolant enable

• Input Voltage: 12V ~ 36V (Depend on the motor driver)
• Operating Voltage: 5V
• Support: 4-Axis Support
• 2 x End stops for each axis (6 in total)
• A4988/DRV8825 compatible stepper drivers
