To to investigate, a detailed specification for the connections between the masso controller and the table is needed. Available?

Do you sell the clothes loop stepper motor drivers separately?

Or please say what is the specific make and model of your closed loop? Stuffers

Regarding the general [Masso G3 Touch](https://www.masso.com.au/product/masso-touch-mill-router-cnc-controller/) CNC controller, here is the [MASSO Documentation](https://docs.masso.com.au/Welcome).

On these closed loop stepper motors from Masso, the drivers are integral part of the motors.

For replacement parts in general, you may go to the [Shop](https://www.onefinitycnc.com) and see what’s under [Replacements parts](https://www.onefinitycnc.com/replacement-parts).
