Thanks Kit, I've read through a few times and I think that talley's with my understanding. The problem is, I can't get to the collector or emitter in the drive, and only the collector on the UB1, so I don't have a lot of wiggle room to add pull up or down resistors?

It definitely all worked before reprogramming the drivers, it's just a hassle now everything is in place, but that's the first step.

Are the drives powered up when your trying to enable them.? If so it should work if you have switched the Active state to High in the drive it's self and pulled the Opto high. To test the drives then just reset Active state and disconnect the enable.
