Not Extruding When Printing, But Extruding When Changing Material

[codyelizabeth 0]

Hey everyone.

I am having problems with my Ultimaker 2+.

When I change the material, the filament comes out like it should, but when I try to print something, nothing comes out.

Also, the filament has been getting stuck in the bowden tube, and I have had to manually remove it twice.

Does anyone have any ideas?

Hi,

what kind of filament are you using? By chance a cheap brand? Sometimes the filament diameter is not consistent and the feeder motor has a hard time pushing it through.

And how old is your printer? What did you print before? There are a few reasons why it may fail so the better you describe it, the better we can help you.
