Am needed to build a closed loop machine. I am going to get Step motor+encoder+regulator/controller. I would therefore like to know the Mach 3 is compatible to such acombination. Also tell me whether the regulator/controller corrects the errors from mach 3 independently.
T he Mach3 doesn't support closed-loop servo systems that correct errors on the fly. It works with those systems that close the loop at the driver. This means that if the driver senses an error it will send a signal that can shut down the system and stop further damage from being done. But if you need a true servo system that will sense errors and compensate for them without stopping, try Badog CNC for the controllers.
