Burnt filament

Hello. This topic is more suitable for all owners of Creality printers whose extruders support “Unicorn” nozzles.


As the owner of a K1 SE, I started my first print with the stock nozzle that came with the extruder when it arrived at my home.

It started spitting burnt filament. I decided to replace it with another Unicorn. I inserted it and tightened it according to the instructions, while it was hot. Nothing changed.

What corrections have you made on this type of printer? Before that, there was (and still is) a V3 KE with Volcano nozzles, and this has never happened before.

Share your experience. I searched extensively online, tried various approaches, reviewed options, and refined my approach—with no results.
