Re: [CAD_CAM_EDM_DRO] spindle start and stop

Is the spindle motor AD or DC? You can use the output from the parallel port
to operate an electronic relay. These usually use 3 to 35 volts DC to turn
the relay on and 0 volts to turn it off. You just need to get a relay
designed for the voltage you are trying to control.
