I had a small print I needed and came back after it should have finish. This was stuck on the nozzle.It was pulled off of the bed and melted onto the nozzle. Nice fire hazard!
I recently had a similar issue, with petg. The blob that cooked onto my nozzle fried the thermisitor - AB temp from my poor Cr10 Smart Pro. Fortunately I had one more nozzle set ready to go (with heating element, etc. all ready to plug in) for some reason Creality seems to cement them in place so fully kitted out nozzles seem to be the easy solution for now. Applogies for typo’s etc. This forum site is not very friendly on mobile. And if you got flagged Loosenut, it was me trying to navigate the interface which was jumping around like a frog on a hot skillet! Definitely not a complaint!
I was lucky, I pulled the blob off of the hot end and the printer was still OK.
