If you have them too tight you may get stalls. If you have them too loose the gears will slip with a horrible grinding sound.

I am not saying this is your problem but if your motors are hot it sounds like they are straining. Perhaps this is why. At least its worth a check.

Perhaps the error message is not really stating the problem and it really should say it stalled.

Thanks Greg, I'll check the threaded screws on the side. Can they just be turned by hand? Completely agree about the 3-way switch!

Also, do your motors run warm at all?
