Hi Leo - I looked up the NK105 and it is a motion controller. It is not a machine controller unless it came with its own machine control software. So you will need to use UCCNC/Mach or similiar to drive the NK105 which then sends/receives signals to/from the motor drivers and peripherals.. Peter Its a 3 axis controller (NK105-g3) if your machine has 4 drives then you will need a new 4 axis controller.
