Transform your CNC machine with the PwnCNC Conversion Kit—a complete electronics upgrade designed around the powerful Masso Touch Controller and PwnCNC’s proven closed-loop stepper systems. Whether you’re just starting out or looking to unlock industrial-level features like ATC (Automatic Tool Changer), we have the right option for you.
Why Choose a Conversion Kit?
Many CNC machines ship with limited controllers and open-loop stepper motors that can stall, lose steps, or cause failed carves. Our Conversion Kits replace the stock electronics with a professional-grade system built for accuracy, reliability, and ease of use. Every kit is pre-configured, tested, and backed by PwnCNC’s U.S.-based support.
Conversion Kit Core
The Core Kit is the most affordable way to bring Masso control to your CNC. It includes everything needed to get running with precision stepper control and homing, without the complexity of industrial features. Ideal for makers, hobbyists, and small business users who want plug-and-play reliability without paying for functionality they may not need (yet).
Includes:
-
Masso Touch Controller w/Core Software Tier
-
(4) 1.2Nm Closed-Loop Stepper Motors (Z stepper includes brake)
-
Pre-assembled cable harnesses with shielded wires for EMI protection
-
Power supply box (36v)
-
(4) Proximity homing sensors
-
All necessary connectors and ferrules for quick installation
Conversion Kit Advanced
The Advanced Kit is our flagship system, built for serious CNC users who want to unlock every Masso feature. With support for ATC systems, tool setters, rotary axes, spindle control, and more, this kit is designed for customers who want professional-grade performance out of their machine.
Includes everything in the Core Kit, plus:
-
Masso Touch Controller w/Advanced Software Tier
-
Support for ATC (Automatic Tool Changer)
-
Full spindle integration (PWM/Modbus)
-
Double-Shielded Stepper Wires

FAQ
Q: Can I upgrade from Core to Advanced later?
Yes! You can start with the Core Kit and later upgrade to Advanced firmware by purchasing the Masso Advanced software tier and adding accessories like the Inlets Panel or Tool Setter. Your Core controller will still be wired with ferrules, however it is possible to add aircraft inlets.
Q: Do I need to modify my machine to install the kit?
Some machines are plug-and-play, while others may require simple brackets for homing switches. We provide support, STL files, and guidance to make installation as smooth as possible.
Q: What makes PwnCNC’s wiring different?
All of our stepper and signal wires are shielded to prevent EMI interference—something most other hobby CNC brands skip. This ensures stable, reliable operation even with spindles, chillers, and vacuums running.
Q: Will this void my CNC’s warranty?
Yes, replacing the stock electronics will void the OEM warranty. However, many users find the reliability of our system far outweighs the limitations of stock controllers.
Q: How does the Core kit compare to competitors?
Unlike typical hobby CNC controllers that rely on external laptops, our Masso-powered kits are standalone systems with industrial reliability—no drivers, Windows updates, or USB cables needed.
