I am building a laser cutter and I am using external stepper drivers to power stepper motors. I have a driver for an optional stepper motor for a rotary attachment. I would only disconnect or connect the optional motor when the machine is powered off. Can I power the external stepper driver without the stepper motor connected, as long as I don't connect/disconnect the motor while it is powered?
