Your problem is communication between the PC/controller software and the hardware, as you are trying to get this working with Mach3 your best place for help is the Mach3 Forum -
General Mach Discussion
you are far more likely to find someone with relevant experience there than here.
Should you be unable to find the required driver/plugin all is not lost as replacing the chinese hardware with something Mach3 compatible need not break the bank, is not horribly complex, and has already been done many times by others -
