I can’t for the life of me figure out what’s wrong. It either wrecks the print like in the video or it doesn’t extrude any
Material at all. Cold pulled, cleaned, cooled, heated - even swapped the extruder and the hotend twice - including the filament sensor, the tubes and connectors and even the filament cutter. The result is always a failed print. Maschine worked for 5 weeks after it was delivered and then stopped. Any ideas? Thank you
