Description
Product Description
The CNC Shield V3 is an Arduino-compatible controller expansion board designed for CNC engraving machines, mini CNC routers, laser engravers, and DIY 3D printer projects. It provides a convenient interface for connecting stepper motor drivers, limit switches, spindle/laser control, and other CNC components.
The shield is commonly used with Arduino Uno and GRBL-based CNC controllers. It supports plug-in stepper motor driver modules such as A4988 and DRV8825, making it easy to build and configure a multi-axis motion control system.
The modular design reduces wiring complexity and provides convenient connections for stepper motors and CNC peripherals.

Important Note
Stepper motor driver modules, Arduino Uno board, motors, power supply, and other peripherals are not included unless specifically mentioned in the product package.
Driver compatibility, axis configuration, pin assignments, and supported functions can vary depending on the CNC Shield V3 version and GRBL configuration. Always verify the board markings and wiring before powering the system.
This expansion board as a driver expansion board, can be used for engraving machines, 3D printers, CNC. It is a total of four slots, can drive four A4988 stepper motor. Each road stepper motors only need two IO ports. In other words, six IO ports can be well managed three stepper motors.
The CNC shield V3 for Engraving Machine 3D Printer A4988 DRV8825 driver expansion board is very convenient to use. After insert Arduino CNC Shield V3.0 into Arduino UNO, and installed GRBL firmware then you can quickly DIY a CNC engraving machine.
