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.
