PwnCNC CNC Conversion Kit with MASSO G3 Touch
Replace outdated CNC electronics with a modern MASSO-based control system, available with Core or Advanced firmware and optional closed-loop stepper motors.
This conversion kit is designed for compatible hobby, prosumer, and custom CNC machines that need a more capable, serviceable, and expandable control system. It is based on the same control platform used in PwnCNC machines and can be configured with no motors, 2Nm motors, or 3Nm motors.

Not sure which configuration fits your CNC?
Compatibility depends on your machine, motor mounts, couplers, wiring, homing switches, spindle or router setup, available power, accessories, and the amount of machine-specific work required.
Our free review can help identify standard PwnCNC products commonly compatible with the information you provide. It does not include custom machine design, electrical diagnosis, installation planning, or validation of third-party modifications.
Choose Your Firmware Level
- Core firmware: A streamlined configuration for straightforward CNC control and common machine conversions.
- Advanced firmware: Adds expanded capability for more complex accessories, automation, and future upgrades.
Select the firmware level that matches your current requirements and expected upgrade path.
Choose Your Motor Package
- No steppers: For qualified builds where compatible motors will be supplied separately or reused after verification.
- 2Nm closed-loop package: Includes motors for X, Y, and B plus a Z-axis motor with electric brake.
- 3Nm closed-loop package: Higher-torque option for heavier gantries, more demanding machines, or customers wanting additional motion-system headroom.
What’s Included
- PwnCNC-branded MASSO G3 Touch controller with the selected firmware level
- PwnCNC power box with 36V power supply
- 110V or 220V AC input support
- Four proximity homing switches
- Shielded stepper cables
- Selected closed-loop stepper motor package, when chosen
- Z-axis brake motor with the 2Nm and 3Nm motor packages
What Is Not Included
This product provides the CNC control electronics and selected motion components. The following are sold separately unless specifically shown as part of another package:
- Spindle or router system
- XYZ probe
- Tool setter
- Rotary axis
- Automatic tool changer
- Machine-specific brackets, couplers, or mechanical adapters
Machine Compatibility
Suitable for many NEMA 23-based hobby and prosumer CNC machines, including select Onefinity, Shapeoko, OpenBuilds, WorkBee, X-Carve, Stepcraft, Mega V, New-Carve, and custom machines. Compatibility is not universal and should be verified before ordering.
Some machines require replacement couplers, new switch brackets, rewiring, motor changes, or other machine-specific modifications.
Installation Requirements
- Removal of the original controller and related electronics
- Basic mechanical and electrical installation skills
- Ferrule and Phoenix-style connector work
- Proper grounding and shield-drain practices
- Machine-specific mounting, alignment, configuration, and calibration
A ferrule crimping tool is strongly recommended when trimming or modifying wiring.

Installation Responsibility
This conversion kit is a customer-installed product. PwnCNC provides published documentation and general product-specific guidance for the PwnCNC components included with the kit.
Machine-specific fabrication, rewiring, mounting, calibration, homing configuration, and third-party component integration are not included. Customers requiring hands-on installation should work with a qualified local CNC technician or electrical integrator.
Production Time
These kits are made to order. Typical production time is approximately one to three weeks before shipment. This is an estimate and may vary based on configuration, staffing, and component availability.
Compatibility and Warranty
Installing this kit requires removing the machine’s original electronics and will typically void the original manufacturer’s warranty. Original motors and accessories may be proprietary, undocumented, modified, or unsuitable for reuse.
PwnCNC cannot guarantee compatibility with every third-party machine or component. Customers are responsible for verifying mechanical fit, installation requirements, and compatibility with components not supplied by PwnCNC.
Warranty coverage for PwnCNC-manufactured and third-party components is governed by the PwnCNC Limited Warranty.
