Every time there is a change in direction (dir) your driver will be disabled. The direction pin and step pin should be connected to pins (2 & 3) for X, (4 & 5) for Y, (6 & 7) for Z. Find out which pairs of pins refer to X, Y, Z. The enable pins should be connected together, you can use either a high or low (ena+, ena-) to enable them.
2nd. Each stepper driver should be connected individually and directly to the power supply, do not daisy chain. You want each driver to see the same current.
3rd. Double check the voltage and current needed for the enable function.
4th. In summary, wire each driver directly to the power supply. The enable pins can be wired together (ena+, ena-). It looks like you have chosen (ena+) which means that (ena-) will have nothing connected to it. You only need (Puls , Dir ) connected to the BoB. In other words, if your BoB uses pins 2 and 3 for X step and direction, then pin 2 of the BoB would connect to either (Puls + or Puls-) NOT BOTH. Pin 3 direction would connect to either ( Dir+ or Dir-) NOT BOTH.
There should be 3 pairs (Puls, Dir) wires total.
Do not give up you are almost there.
Hope this helps,
