If you look close at pics 4&5 you will see a brown wire with a white stripe on one side (looks almost like a white wire) going from the 5vdc+ on the breakout board to the PUL+ and a jumper from PUL+ to Dir+ on each controllers. I have put a volt meter on all three and they all have 5vdc power. I also checked all three power supplies and they all have the proper power output. I rechecked all connections and wires to be sure they are all in the proper places.
