Had a lot of intermittent issues so went through the molex connectors and found a lot of loose connections car ran for a couple months. Now the issue is if it sits at the top landing 2nd floor (only a 2 stop) and you hit the first floor hall call it opens the doors on 2 and shuts down. I checked the selector it’s stepping correctly and usd and dsd switches are good any other ideas are appropriated. Or if anyone knows how to program parking of these are even capable of it that was my other idea keep it on 1 and problem solved. Thanks in advance.
