I was reading this post "so-i-fried-my-smoothieboard", and was wondering how one could avoid a situation where the motor acts as a generator back to the board, causing it to break. I have had other boards were moving the motors was not an issues even when they were turned on; was this just a freak accident or is it something that happens often? Also could it be avoided by placing a diode in series with the stepper driver, or would that stop it from turning in both directions? I have read the warnings and it does not appear to be discussed there, are there any other common ways of blowing the board that I should be aware of before setting it up?
