I'm thinking the Sled Docking is at the root of this. Sled Docking got added to the main Marlin release. And there were errors in the #ifdef's that caused a lot of compilation issues. The way Dacb dealt with the errors and what I have are different. So I'm going to go through those differences and see if I can find something that explains this behavior.

I have a post outstanding to Dacb on another issue in the G29 related to the declared bed size. I don't think that is your problem but it should be dealt with.

I'm not sure how to proceed, but depending upon what I find, it might make sense to make the changes to your Marlin_main.cpp and upload it here for you to try.
