Hi, Hood

Will he need to add a separate spindle pickup or is there a way to use the pwm info. ?

As far as I know it will need a single pulse per rev input. What Mach does at the moment as far as a G95 move with no feedback is throw a message then go on its merry way and just assumes that the spindle is turning at the commanded rate. To my mind this is totally wrong, it should throw the message and then do nothing. The way it is at the moment your spindle may not have switched on and Mach will plough the tool into the stock regardless.
