Help with wiring DMM drives step and direction signal

If this is in wrong section please move.
I am trying to get my plasma cutter moving and have run into a wall.
Specs;
DMM Ac servos and Dyn 4 drives
CandCNC MP3500 torch ht controller.
I can get the motors to run through the DMM software, but I can not get mach3 to move them. The DRo in Mach moves but motor does not. Any help would be greatly appreciated, as Candcnc is gone today and all weekend, and DMM doesn't seem to answer phone or email.
I have tried wiring it as the DMM manual shows for open collector internal power supply and no luck. I was assured when I bought the drives and motors that they would work togther.

Ok, now I know its been a long couple of days. Took a break, ate some dinner, came back and started checking with the multimeter, stupid me had step and direction flipped. Now it works.
Now to move the motors into the racks and get all axis moving..

Any one have tips on servo tuning. I got my X and Z dialed in great (DST 750watt) but my dual Y gantry drive (DHT 750 watt) I am having a hell of a time with. If I get the main gain up then one side likes to vibrate like mad, and now (didn't seem to at first but I don't know anymore) even at the default settings, one side will do fine, other side keeps getting lost phase.
