| If you do not want to be bothered to place M codes throughout, the practical way may be to place an external hardware timer relay that would replace the normal on/off relay and it would cycle on/off at preset times, It would be picked up by a M code at the start of the pgm and another at the end to disable it. I am not sure if Mach has a software timer function to implement this in software? You could also place an external bybass toggle switch to effect a continuous on time. Al.
