OK after talking with the tech guy he had me jump the en pin which allowed me to get a signal from the BOB. Unfortunately I still have no movement. One thing he did mention is the motors should lock up when the drivers green light is on regardless of the BOB signal. My motors are not locking up at all and I'm wondering what kind of signals I should be getting out of the driver and if there is a way to ohm out the motors?

anybody know what the signals should look like coming from the driver. Voltage or scope waveforms. I would like to know when the motors are supposed to be locked and when they are supposed to be moving. Also does anyone kno w if anything is supposed to be connected to the "ena" portion of the drivers? Thanks again

Ena is Enable it it either high (+5V) or low (0v) check with your board suppliers data sheet.
The stepper signals are either +V (whatever voltage they are being driven at) or 0V (alternating if being driven) it is a square wave.
