CNC Shield is a versatile control board compatible with Arduino Uno and GRBL, designed to expand your 3D printer, CNC router, or engraver. It supports multiple stepper drivers, enables 4‑axis control (X, Y, Z, and A), and operates on 12–36V DC. With plug‑and‑play Arduino Uno integration, modular driver options, and expansion ports for spindle, coolant, and end-stops, it enhances motion precision at an affordable price.
