Rhythmic grinding noise from the extruder
Hello, I just assembled my Prusa MK4 kit. The first couple of prints, it worked just fine, including some with the same no-name PETG I'm using now. Now, I'm printing transport handles for the enclosure, and the extruder started making these weird rhythmic "khrrr-khrrr-khrrr" grinding/screeching noises. Here's the video: https://1drv.ms/v/s!AkXWogeMUlFCxmMGCgBCfIRfnLoe?e=pRJhZW. The sound seems to be proportional to the speed of extrusion. Sometimes it becomes less noticeable and sometimes more, but it's definitely there all the time. Any ideas what it might be? I had an MK3S for a couple of years, and it never did noises like that, so I don't know what to think...
