Remove the wire going to the Enable on the drives you don't need that. This won't be your problem as it's not going to ground but still remove it.

Other than that it looks correctly wired. So if your still not getting any motor movement then you must have the control software set wrong.
The VDD Clive mentions is if you use 10V I think and you have to change a jumper on the board if using 10V.

One more thing is take off the tie wrap cable ties. It's not a good idea to strap signal wires together with power wires as you'll get cross contamination on the signals from EMF electrical noise.
Also if the wire your using for the motors isn't shielded and the shield correctly grounded then you could end up with problems from electrical noise causeing false e-stops or worse missed steps etc.

Show some screen shots of how you set the Motor outputs in control software.
