Is my stepper motor failing? (discuss.tchncs.de)

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?

Unlikely that it's the stepper. It sounds like something's scraping. I heard similar noises after inconsistent extrusion on infill, so that the infill was standing up a little bit and the print head was scraping over it.

Could also be ball bearings or something else in there that's scraping over something. It is most likely something connected to the motion.
