CNC SHIELD

The Arduino CNC Shield V3.10 plugs directly onto an Arduino UNO and, with GRBL firmware installed, turns it into a full CNC controller. Supports up to 4 axes (X, Y, Z, A) with removable Pololu-compatible stepper drivers (A4988, DRV8825 — not included). Micro-stepping configurable via jumpers. Compatible with engraving machines, 3D printers, and CNC routers.

Note: Stepper drivers not included. Requires soldering for some connections.
