Hello Gerry.
I Install all again a recheck all my steps carefully. I revise deeply Mach3 tutorial and I am almost sure that all my inputs and output and settings are correct. I am having a friend electric engineer, that loves electronics that is going to help me check the electric response of the different components. What concerns me is that the machine was working nicely till I reinstall Windows XP and Mach3 2.48. Since then every thing works OK except the motors. No movement, no noise, they get lightly warm and engage. I am using 4 G.203V and 4 Oriental PK296_2A-7.2 and a PMDX-122 card . Something important. Before I remember that I could hear the motors engaging and not now and if I close the computer with out closing my control box , before motors will make a lot of noise and hard vibration, now they will slightly vibrate. I use a separate 5v source for my breakeboard card.
