My printer just stops printing after about 3-4cm.
Doesnt matter which object or material, it always prints to a certain height, starts stringing like crazy and then stops pulling filament but keeps moving.
Also doesnt matter if its 30 minutes or 3 hours, always at the same height. Since I'm a bit new to 3d printing, any ideas? I've already tried different speeds and retraction settings but i dont really know much about it
