From what I can see, the hardware is probably correct… at least you have wires where there should be wires…
There has been a lot of discussion over using the U axes with a rotary on a 6445 and you might benefit from reading some of these threads. I don’t have a 6445, so I haven’t tried to run my rotary off the U axes on the 6442 that I own… actually I don’t think mine supports a U axes rotary.
