I don't have your system but, from things that I've read here on the zone, I'd say your new 24v, 1.9amp power supply doesn't have enough amps to run all 3 axis. It may just be big enough to run one axis. You might try hooking up one axis and jogging it around to see if that's it.
P.S. I just finished my first control box, so I'm a newbie.
