One of my motors has started to grind every almost every time I print. I’ve tried reducing the retraction but that has;t helped. I also tried doing the screw up a little as per the the maintenance (although I was;t sure how much to tighten, so didn’t do this too much as I didn;t want to damage anything. It was tighter however than the other one which is not grinding/slipping).
So, does anyone has any ideas? Should I take it apart and maybe give it a clean? Is there any guide on this before I jump in?
