MASSO – The PC-less controller
Powerful. Stable. Guaranteed.

It doesn’t matter if you’re a large OEM or a DIY enthusiast,
MASSO means an end to all of the headaches you get with PC-based controllers.


MASSO CNC controllers don’t use a PC—at all.
We provide a fully integrated solution for CNC control—motion card, software, and GUI—all in a single, self-contained platform. MASSO means an end to all of the headaches you get with PC-based controllers.
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.
And there are no hard drives or file corruption to concern yourself with—just a lightning fast ARM CPU in a passively cooled system. And for that same reason, power interruptions won’t hurt a MASSO. With the MASSO’s job-resume functionality, they’ll hardly even slow you down.
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.
