PwnCNC Conversion Kit

⚙️ PwnCNC Masso Conversion Kit – Core

Upgrade any compatible CNC machine with reliable, modern electronics and a clear upgrade path.

The Conversion Kit Core is designed for builders who want the power and stability of the Masso G3 Touch controller without the additional I/O complexity of the Advanced kit. It’s the same foundation we use in our Dominator Core CNC, packaged to retrofit existing machines or custom builds with confidence.

Note: These kits are made-to-order. Please allow one to two weeks for assembly and shipment.

✅ What’s Included

Masso G3 Touch Controller (PwnCNC-Branded)
Core-level firmware preinstalled and configured

Closed-Loop Stepper Motors

(3) High-performance motors for X and dual-Y
(1) Z-axis motor with electric brake for added safety

PwnCNC Power Box

36V power supply
Supports 110V or 220V AC input
* Power supply enclosure design may differ from photos

Proximity Homing Switches (x4)
Accurate, repeatable homing just like a professional machine

Shielded Stepper Cables
Physically shielded cables for EMI protection
For best performance, shield drains must be properly grounded

🧰 What You’ll Need

A CNC Machine
Most hobby-class and prosumer machines will work, including Onefinity, Shapeoko, OpenBuilds, and custom builds. Look for NEMA 23 motor mounts.

Mounting Locations for Homing Switches
Universal proximity switches are included. If your machine does not have mounting points, we can provide 3D-printable bracket designs or guidance.

Willingness to Dive In
This is a full electronics conversion. We’ve done the hard work up front, but some machine-specific setup is expected. We guide you through it step-by-step.

Basic Familiarity with Ferrules
Wiring is done using ferrules and Phoenix connectors. This approach reduces cost and keeps the kit flexible across many machine types. A ferrule crimping tool is strongly recommended if you plan to trim or resize wires.

📘 Installation & Setup Documentation

We maintain a dedicated Conversion Kit Knowledge Base that walks you through the entire process, including:

What is pre-wired and pre-programmed
What steps are machine-specific
Grounding and noise immunity best practices
Motor alignment and coupler setup
Homing, first power-on, and validation checks
When to troubleshoot and when to stop

⚠️ Compatibility & Warranty

Installing this kit requires removing your machine’s original electronics and will typically void the original manufacturer warranty. Once installed, you’ll have a significantly more capable, serviceable, and expandable control system.
