does anyone have an idea what is going on here (left one on the picture)? I have a blob with so many filament on my print, so that my print fails. It looks like, that this comes out at one time. It happens very often. Is something wrong with my extruder?
I dont know what i can do wrong there with the assembly? Its screwed in tight with a sort of wrench. But it looks like that it would squeeze out of the side of it. Maybe when the nozzle is clogged by the time? Is there a rule of thumb to change the nozzle after a period of printing?
