Help please. I have had the creality cr-10 se for a month now and the last couple of days, the nozzle area is making a funny noise… like the plastic isn’t being extruded correctly. I’m having issues getting and keeping the heat high in the nozzle too. Plus there’s a burning smell that’s also started. The print is very brittle too. I’m gutted as I’ve been enjoying learning to print and have some lovely models made from the free files on here. This has put abit of a downer on it!! Shall I message creality and ask them to fix it? Bad benchy!
