Hello, I own a Lulzbot Taz 6 and I’m loving it. However there is one main issue I have encountered when I go to print an object, the filament comes out the top where you would insert it to change the filament. The nozzle wipes, then the filament ejects, and then it probes, and begins to print. The filament does not catch so nothing comes out but it thinks its printing something. Any ideas on how to fix this?
