Problems Printing PETG (burned fat strings, dark spots)
I run into problems printing PETG. Burned spots of material and fat (burned) strings that cause layer shifting. Does anyone have an idea what is the cause of that and how to avoid it?
no Prusa Filament
Temperature Extruder 240 C
Temperature Bed 90 C
Default Printing Speed 2400
Thank you very much in advance, Stephan
