MotusCNC™ Integration

The GBM5 is powered by MotusCNC™, a versatile, modular Linux based CNC control software.

MotusCNC is fully integrated into the GBM5 system. MotusCNC's modular design can allow for customized safety features, visual process monitoring equipment, probes, closed loop feedback systems and more! MotusCNC's™ built in crash prevention feature shuttle mode, Shuttle Mode allows for safe and controlled initial G-Code testing. Users have complete control of G-Code progression using the MPG hand dial.
