hi, cnc brothers

I'm have a problem with my new build . i can't get my motors to turn , i do hear a high pitch sound coming from them but no movement, the DRO's in mach 3 does move. i'm pretty sure i hooked everything up right.i don't know what else to do. hoping you guys can help me out. i attach a pdf document with my settings ,maybe you guys can see something i'm missing ..thanks
