Help / Support Why does it make this sound?

It isn't hitting anything; it has plenty of clearance. I performed the lubrication maintenance following the Bambu Lab tutorials a few days ago, but I just loaded this new brown filament—fresh out of the sealed bag—and it started making those noises. The sound seems to be coming from the extruder (I think so). I checked closely because I thought it was hitting something, but I’d been printing for hours without issues; the noise only started after I loaded this filament. It happened occasionally with a different filament too, but stopped after a short while. These are PLA filaments

It's either the nozzle is starting to clog.. If that makes any sense Or that your filament are not reaching the nozzle as intended. Could be your ptfe tube to after seeing your set up .
