If the machine has been transported, most likely one of the connectors or circuits on the drive units has a bad connection. Sometimes reseating them will cure the problem. Check your drive units for codes or error indicators to try to determine which unit is causing the problem. It's possible that the drive unit went bad, but much more likely that something jiggled loose during machine movement. Yes i've seen it before especially if the machine isn't shipped air ride.
