Related question (I hope)? I am building my second reprap with a rambo using a 24 volt p/s. Since I want to limit the amount of damage if I discover something about the 24 volt under fire, I wanted to get my hot end and bed working without the motors connected (foolishly or not, I figured that might protect the motor drivers). I knew as mentioned above not to unplug the motors under power. My question is.....what about powering up the rambo with no motors conected (or maybe one for the extruder)? Is that likely to cause problems even if I don't plug anything in under power?
