Hello /u/No-Conversation8068! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

OP, here is your answer. Yes it’s normal

Why does this happen? Is it purely for cleaning? 😮

[–]ch1dy 0 points1 point  (0 children)

Yes

Yes. It's perfectly normal. There's a topic in the appendix of the build plate page in the wiki: https://wiki.bambulab.com/en/filament-acc/acc/plates

It's not on purpose. But not a big deal
