CNC Shield V3 compatible with Arduino Nano, controlling 4 stepper motors via GRBL firmware. Ideal for CNC routers, laser engravers, and robotics projects.
Kit version: headers and terminals require soldering.
This CNC Shield V3 is designed to plug directly into an Arduino Nano V3, transforming your microcontroller board into a powerful multi-axis stepper motor controller. Compatible with the GRBL firmware, it converts G-code commands into precise positioning signals, making it perfect for DIY CNC routers, laser engravers, and 3D printers.
The shield supports up to 4 axes (X, Y, Z, and A) via four sockets for stepper driver modules (A4988 or DRV8825). It provides dedicated headers for limit switches, spindle control (enable/direction), coolant output, and essential control signals like Abort, Feed Hold, and Resume. It is an excellent solution for building custom machining or cutting machines.
