Well that may work fine for you and honestly I love soft limits as much as the next Guy but I honestly prefer to have the drives enabled in a limit switch trip situation so I can just backoff,backup and punt my way back into the program. It worked fine that way on my RF45. If I have my way I will have both hard and soft limits working continually and the estop shutting down the show in an emergency situation. So I appreciate all the ideas here but can we kinda keep the ideas pointing in that direction so my already befuddled mind does not get any more befuddled than it has to be. LOL thanks guys....peace
