False nozzle clumping error

Just wondering, as it’s the first time I’ve run into this v I’m getting the nozzle clumping error. The picture is showing the filament that was causing the error. Is it my wiper/cleaner is getting worn? I lowered the AI, and cleaned off the little bit of filament.

And for the life of me, I am not able to clear the error showing on the GUI( and the AI assistant) even though the print has resumed?

TIA

Its a good idea to heat up the hot end and clean it with a bronze brush. After many hours of printing there is a filament residue build up on the tip that gets baked on. I do it on mine very 300-600 hours otherwise I get those errors.

Thanks man! Ok, I’ll clean it… my wife was at home and she cleaned it, but when this print is done, I’ll take the sock off and clean it good!

Thanks much again!
