Bob, I have had the same go on with out 29.3 just the other day. We don't know why it was doing that as it was working fine just before.:banged: But you did what I did, Override the system and then resync. At first I thought there might have a screw or something getting caught in the tracks. The front would stop but the rear motor would keep going until it figured out it wasn't going in correctly. While I was over-riding the system to bring it back in, there was a huge pop and then it would start to come in like nothing was wrong. We are out on vacation now and not had it repeat it again.
