The COM jumper is not set correctly on the BOB, you have the drives wired as common 5V but the BOB is still set for common GND.

Tom - that was it!! It moves now!!

I didn't realize that the 5V was needed on the common - the comment by Mike above got me to do some googling it this evening and I saw that there was a jumper on the BOB - you confirmed it!!

Thanks so much to everyone who replied!!

Jeff
