Masso G3-Touch CNC Controller

Integrated 15” Touchscreen Standalone CNC Control System

Overview

The Masso G3 Touch is a professional-grade, all-in-one CNC controller featuring a 15" capacitive touchscreen — engineered for precise control without the need for a PC, motion cards, or complex drivers.

Power it up, wire your stepper or servo drivers, configure your axes, and you're ready to machine. It’s an ideal solution for mills, routers, lasers, plasma cutters, and more.

Not sure if Masso is the right controller path for your CNC?

Controller upgrades can depend on your machine, motors, drivers, spindle, accessories, wiring comfort, and how much of the conversion you want to handle yourself. If you are unsure whether to buy a standalone Masso G3 Touch or a complete PwnCNC Conversion Kit, submit a free CNC Upgrade Compatibility Review and we’ll help point you in the right direction.

Masso G3 Touch vs. PwnCNC Conversion Kit

This is a vanilla Masso G3 Touch — no modifications, wiring, enclosure, or PwnCNC enhancements applied. It’s best suited for advanced users, custom builders, or customers who want to design and wire their own controller system from scratch.

If you'd prefer a prewired, plug-and-play-focused solution, our PwnCNC Masso Conversion Kit includes:

This G3 Touch controller
PwnCNC pre-configured wiring
Inlets panel for accessories
Enclosure, power box, stepper motors, homing switches, and more

Compatibility

The Masso G3 Touch can be used on many CNC routers, mills, lathes, plasma tables, lasers, and other CNC platforms when wired and configured correctly.

Important Notes

This product is the standalone Masso G3 Touch controller only.
It does not include a PwnCNC enclosure, wiring harness, power supply, inlets panel, motors, sensors, or machine-specific conversion components unless separately purchased.
This controller requires proper wiring, configuration, grounding, and machine-specific setup.
Controller conversion work may require electrical knowledge, machine documentation, and troubleshooting.
Support for non-PwnCNC machines, third-party electronics, or custom conversions may be limited by available documentation.
For a more complete prewired option, consider the PwnCNC Masso Conversion Kit.
