Feeder not working

Recommended Posts

Suddenly the feeder on the back of the UM2 is making a tuck-tuck noise. I can see the motor axis going forward for a quarter and then back again.

The hotend is working. I can push filament by hand and it extrudes normaly.

Actually the feeder does feed some filament, despite the tuck-tuck.

I have opened the cap over the feeder and the inside is very clean. No signs of filaments or anything.(btw, who had the brilliant idea of holding the motor and the plastic parts with the same screws ? :-( )

The white plastic indicators, do they serve any purpose?. Touching the screw does not change the position at all. They are at the top position.

I have replaced the filament without any success. It still makes the tuck-tuck noise.

Pushing the filament through the feeder is not easy, it takes a while for the filament to pass through the feeder. I am using Ultimaker PLA.

Is there any way to fix this please ?.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
