## Description

The Arduino CNC Shield V3.51 by Protoneer turns an Arduino Uno into a 4-axis CNC controller. Compatible with GRBL 0.9 firmware, it accepts Pololu-style stepper drivers (sold separately) and supports up to 4 stepper motors for CNC routers, laser cutters, 3D printers, and other precision motion projects. Version 3.51 adds noise filtering circuitry on all end-stop and probe pins, eliminating false triggers and allowing the use of non-shielded cable. The compact shield stacks directly onto an Arduino Uno. Key Features GRBL 0.9 Compatible – Open-source G-code parser and CNC controller firmware 4-Axis Support – X, Y, Z, and A axis (A can duplicate any axis or run independently with custom firmware) Noise-Filtered End Stops – Filtering on all 6 end-stop pins and probe pin (new in V3.51) Pololu Driver Sockets – Accepts A4988, DRV8825, and compatible stepper drivers Micro-Stepping Jumpers – Configure micro-stepping resolution (up to 1/32 with DRV8825) 12–36V DC Input – Wide voltage range (36V requires DRV8825 drivers) Coolant Enable Pin – Control spindle coolant from G-code Specifications End Stops: 2 per axis (6 total) Motor Connectors: 4-pin Molex or solder pads Power: 12–36V DC Compatible Drivers: Pololu A4988, DRV8825, and pin-compatible modules Ideal For DIY CNC routers and milling machines Laser cutter and engraver builds 3D printer electronics Any project requiring precise stepper motor control Package Contents 1× Arduino CNC Shield V3.51 Important: Stepper motor drivers and Arduino Uno are sold separately. An A4988 Stepper Motor Driver is required for each axis. Resources GRBL Firmware (GitHub) Protoneer Community Forum
