“Simple Circuit converts Step/Dir. signal into to double drive CW/CWW Pulse, Mach3 and few Hobby CNC software’s provides Step/Direction pulse output to drive stepper motor drivers.
Various AC servo works with double CW/CCW pulse. This circuit is solution to interface such AC CW/CCW pulse based driver with Mach3 or other CNC software’s. Circuit designed around 7408 and 7404 IC, board support 5V or 24V supply. Open Collector output can be interface with 24V system by changing output resistors.”
