UM2+ Filament not coming out when running Print

Recommended Posts

Posted · UM2+ Filament not coming out when running Print

Hello, 

 

I have tried everything possible before resorting to this post. A week ago my Ultimaker 2+ was grinding filament, I have cleaned the feeder completely, reset the tension, the material comes in and also extrudes when using everything besides the Print option. When running a print the gear simply does not move and there is nothing extruding. What do you think the problem could be?

Is the feeder *gear* not moving? Then this would indicate a slipping feeder wheel on its axis, maybe a screw that came loose in the feeder.

 

Or is the gear moving but grinding the filament, and thus the *filament* not moving? Then I would suggest that you disconnect the bowden tube and manually insert a piece of filament and try to extrude manually. Directly into the nozzle. Clean the nozzle if necessary, and inspect the teflon coupler on deformation. Also, separately inspect every part in the whole feeding traject on too high friction: spool, feeder, bowden tube, nozzle. Also check filament diameter.
