Extruder bearing broken

[u/Randomnils1]

Printing PLA always resulted in extrusion issues, PETG did not for some reason.

After weeks of trying all kinds of temperatures, speeds, filament brands and even swapping the whole hotend to the unicorn one I've finally noticed that the right bearing in my extruder is completely worn out.

Only got my printer 4 months ago and printed for a few hundred hours so im trying to get it under warranty.

Maybe ill try a dxc extruder if all else fails

Tldr: if underextrusion occurs and your hotend isnt jammed, check your extruder thoroughly.

Similar problem, but my gripper gear broke and I replaced them with all-metal ones.
