You CANNOT use a USB to LPT adaptor either . It has to be a USB or Ethernet motion control board that HAS a Mach3 plugin so that it can run Mach3. The plugin is UP TO teh Manf of teh Motion control card not Mach3. SO IF they support THC then you will have it if they do NOT support THC then you won't.
Yes I am telling you that teh USB THC would be VERY slow compared to teh LPT. With USB functions your THC controller has to signal teh Motion controller then the motion controller has to signal MACH3 to do a THC move THEN Mach3 has to plan it and then talk BACK to teh controller to tell it to move Z. THAT takes time.
WITH the LPT version Mach3 sees teh THC signal at kernal speed and responds directly the LPT port. It happens in uS not mS.
