You've got a jam. Filament is dried and burnt up in there. PETG is a lot more fluid / lower viscosity when hot, so it's flowing around the crusty. Take off nozzle, remove PET tube. You should have another PET tube in the spares bag that came with the printer. Clean out the extruder well.
I did have nozzle cleaned but my ptfe tube is totally melted and i lost the spare so i flipped it and it did helped a lot i have managed to print something without a fail but still only at high temperature 235C so i had a lot of strings so tomorow i will try to find the replacement i hope it will fix it![](https://lemmy.world/pictrs/image/c611f12d-1261-4ffe-9f30-d09b7aa1b5dc.jpeg)
Its weird for all metal hotend. Not sure how assembly looks exactly, but make sure your hotend fan is working properly.
At least you found a problem
Yeah, that's bad.
What extruder are you using that has PTFE tube that close to hotend? and want to print that high temperatures?
I wouldn't go above 220C unless its a proper all metal hotend.
cut it with a sharp knife ?
