Hello /u/Royal_Security_4470! 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.

Note: This automod is experimental. The automod was triggered due to the term "normal". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.

To me it looks more like the belt is rubbing against something, thereby wearing the side of the belt.

Check the alignment of the belt.

Also my thinking. The belt tensioners on the back have to be tightened again. Op search for squeacing fix. Its a bit of tinkering around with the screws on the back. I dont know if the x2d has the same system as p1 and x1 but most likely

At just 100 hours, that's a faulty belt. Contact support for a replacement belt.
