Part fell of the X1C , what is it?

I found a melted part on the floor of my X1C printer. Does anybody know what is is and how it can be fixed? It looks like a long spring with melted green plastic. Btw, I did not print anything in green.

I have to ask: Are you being serious?

Yes off cause! I have also raised a ticket with Bambulab’s technical service.

If I had to guess, all bambu nozzles are tested with various PLA filament. I guess yours was tested with green and the first black filament you printed mixed with the original green to produce that poop

Ok, apologies. I had to check. That is filament from when it was tested at the factory.
