I am having debris accumulate in the extruder causing a “filament fail to retract” error and shut down prints. The hardened wheels in the extruder are scraping off the surface of the filament. Has anyone adjusted the spring tension screw on the extruder idler wheel with success? I can only back out the screw a little bit due to contact with the print assembly cover. Thanks
I’m interested in this topic.
Which type of filament are you using?
