UCCNC only works with UC motion controllers.
if you wish to use UCCNC you will need to buy a UC motion controller.
That is the way it is designed and allows the software to be 100% compatible and developed for one set of USB and ethernet controllers.
I'd highly suggest you convert to UC motion controllers as they are lightyears ahead of Mach3 (for mill + plasma) which is no longer developed for years.
