Any help will be greatly appreciated. I have an MC-60 treadmill speed controller. I'm mounting the motor on a drill press. I put switch on the wipe terminal on the pot and added a reverse switch on the motor leads. I have it geared way down so that I can do some thread tapping. I'd like to have it start and stop immediately. I'm trying to eliminate the soft start and stop. Putting a switch from the board (red wire to the motor) gives me what I'm looking for but I am concerned about whether the board needs the load from the motor. Is it safe for the speed controller to run with a switch on the motor lead?
