Releasing the All New MASSO G3 controller


The complete motion hardware and software system.

We have added all the CNC motion hardware and interface software so that you can concentrate on your business and machining parts rather than spending time troubleshooting PC driver, parallel ports and motion card issues.
You don’t have to worry about your PC issues interrupting a machining process. You don’t have to think about software compatibility problems or the hassle of updating drivers.
We have it all covered, no need to stress about PC hard drives crashing, file corruption or virus. Keep dust and cuttings away from system with a passively cooled design that does not need any cooling fans. Just a lightning fast system that is ready in seconds after power up.
In short, MASSO is the most stable, reliable, and easy-to-use CNC controller money can buy. And our service matches the quality of our controllers: We offer personalized support and free software updates for life.
