My X1Carbon doesn’t recognise anymore the build plate localisation marquer of any Bambu Lab plate. The problem is not confined to a single plate, but all of them. Not sure what is wrong.
Did you try to clean the lens?

Thanks @cl33 !!!
It worked!!! 
I have been printing ABS for several days, and it makes perfect sense that the lens get dirty

So with the new Supertack build plate I have had the same issues with not reading the plate. What seemed to work was cleaning the plate with 70% or 99% isopropyl alcohol (99% is better) and that seem to do the trick I did have an issue once but that was my fault being lazy and not cleaning the whole plate and leaving my fingerprints in bad areas.
