Recently my extruder gears have started to squeeze quite loudly. It only does this in specific arcs of the gear. So it will not make any noise and the when the right side of both the large gear and the small one it starts to squeak.
I’ve tried to reproduce it by rotating with my hand or by extruding, it only does so when there are a large number of retractions in a small time frame.
I’ve attached a link to a video as well.
What do you guys think? Do I need to apply some lubricant somewhere? Or is it time to replace the gears?
