PLA Ultimaker filament not pushing through new print core

[kribbons 0]

Hi

I noticed the filament was having trouble inserting into the print core. As soon as it reached the top of the print core - it would stop.

I manually forced it though, and it will go through the nozzle so its not blocked, but the filament isnt being pulled through at any rate where it could print. 

I did take the feeder unit apart and the filament moves through the tube correctly - its just the last stage where it fails. 

 

I've tried several print cores and have the same results. 

 

If anyone has ideas on how to solve this it would be greatly appreciated

 

Thanks

Hi @kribbons,

 

Welcome in here.

 

Is this happening on both sides or?

Next, can you feed the filament through when there's no core installed?

Is this a new printer?

 

Thanks
