I’ve checked the print it was working on and changed the Z-offset, had no influence on these scraping sounds. It’s definitely somehow connected to the extrusion, that’s why I assumed it to be the stepper.

Do you think those really tiny bearings used for the extruder axis’ can make such a sound? Other than that I’m really out of ideas outside basically sanding down anything that could be the problem… I even made sure to print the whole MK4 extruder you see in the video on the Prusa MK4S of my local hackspace to make sure it has perfect dimensional correctness etc.
