I noticed the printer moves the nozzle over the back center of the bed on top of the small tab that is on the plate and moves back and front in a small rectangular pattern. It has rubbed off the coating on my plate on both sides. I followed the directions and pictures in the manual but I believe the printer is trying to scan the plate but it going to the wrong location to do so.
@Cjs10mm FYI, the above note is displayed on the product page for all build plates in the Bambu Lab store (here for example).

Thank you all I appreciate it. I guess I missed that as I haven’t ordered a spare plate yet.
No worries. They for sure need to put a sticker or something on the plates that indicate that it’s normal. It was a little alarming to me at first too.
Not sure how it’s “specially designed” when it just runs to bare steel? But sure as long as it the expected result
I think it’s more the added wiping area on the print place is specially designed to be damaged in this way, so that your actual printing area doesn’t get messed up. That part of the plate seems to only serve that function. The nozzle rubs that area back and forth to remove any remaining bit of filament so that the nozzle is completely bare and can perform an accurate automatic bed level.
The filament wiper probably gets most of it, but not all of it, which is why a prime/purge tower is usually needed on multi color prints.
I just got my first Bambu and noticed the same thing. I was thinking about putting a piece of Kaptop on there. Any thoughts?
Seems that would interfere with the intended cleaning, no?
If you don’t want the nozzle to wipe there, it would be better to edit the G-code to disable that.
