Well between yesterday and today something has changed.  I no longer have stepper motor control.  I'm using Mach 3 licensed, and was setting up all the parameters.  I had motor response when I shut down last night and now this morning I can't get them to respond.  I uninstalled and reinstalled Mach 3, used back up config settings from earlier in the day to no avail. 
 
I know this isn't much to go on, but I don't know what else to do.

I sent the control box in, apparently it had a bad capacitor in the
reset circuit.
