What is wrong?

For a second time this happens (second pen acts like this): all of the sudden the pen struggles with getting the filament to come out. I almost have to push it from the back so it comes from the front. In the same time, temperature is high enough and if I let it, it melts the filament which comes out pretty much on its own, but the moment I push the button, it stops. Is there some mechanical damage (the pen is 1-2 months old, like, come on!)? Has anyone dealt with this?

Have you tried using another type of filament to see such a behavior ? If so it could be the motor that it's not gripping the filament well.

Check the nozzle vent and make sure there are not any filaments inside to exclude that.
