CNC Shield V3 Engraver 3D Printer Expansion Shield - A4988 Driver (MD0275)

CNC Shield V3 Engraver & 3D Printer Expansion Shield with A4988 Driver (MD0275) Product Description The CNC Shield V3 Engraver & 3D Printer Expansion Shield (MD0275) is a powerful Arduino UNO expansion board designed for controlling CNC machines, laser engravers, plotters, and 3D printers. Paired with A4988 stepper motor drivers, it provides precise control of up to 4 stepper motors (X, Y, Z, and A axes) while supporting micro-stepping for smooth and accurate motion. The shield is fully compatible with GRBL firmware and supports PWM spindle/laser control, end-stop switches, coolant control, and emergency stop functions. It is an ideal solution for DIY CNC routers, laser engraving machines, drawing robots, and automation projects. Note: Arduino UNO is not included. Features Compatible with Arduino UNO R3 Supports 4-axis stepper motor control (X, Y, Z, A) Includes A4988 stepper motor driver(s) Compatible with A4988 and DRV8825 driver modules Supports micro-stepping via jumper selection GRBL firmware compatible PWM spindle/laser output End-stop switch connections for each axis Supports emergency stop, hold, and resume functions Easy plug-and-play shield design
