The CNC Shield for Arduino UNO is an expansion board that transforms your Arduino into a complete CNC controller. It supports up to four stepper motor drivers (like A4988 or DRV8825) and offers easy connections for limit switches, spindle control, and cooling fan outputs. This shield is ideal for building your own 3D printers, laser cutters, or milling machines.
CNC Shield V3 allows 4-axis control with A4988/DRV8825 drivers for Arduino UNO. Compatible with GRBL firmware, ideal for DIY CNC, laser engravers, and 3D printers.
Axis Support: X, Y, Z + A (Clone)
Motor Drivers: A4988 / DRV8825
Firmware: GRBL Compatible
Power Input: 12V–36V DC
The RAMPS 1.4 Shield is a popular expansion board used with Arduino Mega for controlling 3D printers, CNC machines, and robotics. It supports stepper drivers, heaters, fans, and LCDs, making it ideal for open-source motion control systems.
