Hi All. I am desperate need of some help connecting my vfd to the BoB and setup in Mach3
But to make matters more complicated i am not sure if the relay on the BoB is working properly. It is connected to pin 2 and i only get 3.8v coming out of #2 on the parralel port.
Is there anyone who can help me figure this out please

Thanks guys

Sorry your question doesn't make much sense.   Tell us more about which BoB, what the relay is, what you want to control?
