Motor drives say like the AM882 (Typical) are digital and have stall detection etc. are used after the BOB (and can be connected direct to the PP BUT not recommended) also they are used after the motion controller.
Motion controllers are generally fed from either USB or Ethernet port and they produces the pulses much better than the computer as they generate their own. Some motion controllers also have the BOB built in.
The Gcode is controlled from the machine controller ie Mach3 or Linuxcnc etc and fed to the PP or the motion controllerLast edited by Clive S; 21-01-2016 at 05:17 PM.
