Unlock Precision Control for Your DIY CNC & 3D Printing Projects with the CNC Shield V3!

The CNC Shield V3 is a high-performance expansion board designed specifically for the Arduino Uno R3, offering a powerful and user-friendly platform for controlling stepper motors in CNC routers, 3D printers, laser engravers, and other motion-based automation projects. Built for makers, hobbyists, educators, and small-scale manufacturers, this shield simplifies complex wiring and delivers reliable, repeatable results.

Equipped with four slots for A4988 (or compatible DRV8825) stepper motor drivers, the CNC Shield V3 supports up to four axes (X, Y, Z, and A/E)—making it ideal for multi-axis engraving, 3D printing, or custom robotic applications. The board operates on a wide input voltage range (12V–36V DC), ensuring compatibility with most stepper motors and power supplies used in desktop CNC systems.

Thanks to its stackable, plug-and-play design, you can connect the shield directly onto your Arduino Uno R3 without soldering. Integrated features include limit switch inputs, spindle/laser control pins, emergency stop (E-STOP), and clearly labeled headers for easy wiring. The PCB uses high-quality components, including Chong CD11X capacitors, for stable power delivery and noise reduction—critical for smooth motor operation and print accuracy.

Whether you're building your first 3D printer, upgrading a CNC engraving machine, or prototyping an automated system, the CNC Shield V3 delivers the perfect balance of affordability, reliability, and expandability. Start creating with confidence—your next precision project begins here!

Compatible with:

Arduino Uno R3
A4988 & DRV8825 Stepper Drivers
GRBL Firmware (v1.1+)
3D Printers, CNC Routers, Laser Cutters, Engraving Machines
