I think I am having feeder issues.

[DesignCreateEducate 0]

Good morning everyone,

I recently purchased an UM2 extended for my school, and have made a lot of successful prints. I use only pla filament from 3D universe (3D universe brand, and colorfabb).

Over the last couple of weeks, it seems like I am having feeder issues. The feeder accepts the filament, loads the filament, but when it actually starts a print nothing comes out, and the bowden tube actually seems to "buck" a bit and make a strange loud click.

I have looked and quite a few times I have noticed the feeder can grind into the filament, and I have had to tug hard during a material change to pull out the filament.

I have tried helping overcome any friction by hand guiding the filament at the start of a print, even giving it a light push. No go.

I have learned and executed my first atomic pull, just in case (and now don't know how to replace the bowden tube, because I am not sure how far it goes back in.)

Can you folks please look at the pictures I have supplied for clues. I have tried looking through the forums, but most answers are incomplete for a new user like myself.

Any help and advice is appreciated, including how far to replace the bowden tube.  

Note - back fan seems to be running fine.

Cheers,

Shari
