What the heck is going on with my extruder?

[nathan-peterson 0]

I haven't had many problems with the extruder since I got my ultimaker2 about one year ago. Now all of a sudden it keeps grinding my filament and making all sorts of noises. I've never seen it do anything like that before.

Video#1: Extruder spinning fast

Video#2: Extruder oscillating back and forth (Front View)

Video#3: Extruder oscillating back and forth (Extruder View)

I've tried tightening the spring on the extruder which did not help at all. I've tried using different filaments. I've tried cleaning out the extruder. I've tried atomic push and atomic pull. I have no idea what is going on.

Please help!

thanks,

-Nathan

Hi,

Can you give us your Gcode ? We'll try it to test if it happens the same thing. Then we could know if it's a soft problem or not and continue until we solve the problem (:

can you see light thru the nozzle after atomic pull? the knurled wheel will pick up little bits and lose its effective grip after grinding as well.
