i am new to posting, i have some experience using a cnc mill, however i have never buit one. I am at a bit of a loss on how to proceed from here. I am building a 30" X 8'-0". this is custom machine and not kit . i have Mach3 set up and assigned and configured all myports and pins. i have also tuned the motors correctly. i checked my XY and Z pins with a multimeter, so my parallel port is working properly.

the problem: when the power is kicked on the motors lock up, which i understand is a good thing. however when i jog the motors through Mach 3, the coordinates move in the program, but the motors will not turn. i guess the first thing to check is if i wired it correctly. Not being a kit of parts, i wired and set it up myself, so i may have missed something. please see the attached wiring diagram, and let me know if you see any discrepancies. any help on the issue would be much appreciated.
