Started making these sounds in the middle of the print. It kept extruding though, didn’t stop or something. The stepper motor isn’t that old, but wasn’t expensive either. Anyone knows this sound?

    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.

      Absolutely, yes. If it never made that sound and started with age, do not go sanding anything. Clean and lubricate again and look for broken parts.

      Any point of contact can be making that noise. Including the motor, yes, but everything else is more likely.
