Hi everyone!
I’ve noticed that my printer, like many other users of this model, is experiencing dust buildup on the extruder guide wheel. It feels more like dust from material abrasion or the wheel’s coating. I’ve found many opinions online stating that this is normal because the wheels are breaking in and that all that’s needed is to wipe the dust off. Other opinions said it’s caused by pressing the wheel too hard and needing to be adjusted correctly. So my question is, which of these opinions is more accurate, and is there another solution? I’ll just add that this has been happening with my printer practically since new, and I’ve had it for about two years.
Thanks in advance for your reply.
