Hi,
I have an Ultimaker 2 Go+ . It printed okei but a while a go it started to have problems with the filament. The feeder clicks and the filament is destroyed by the feeder dents. I tried to change the material several times, but is always the same.
I check the nozzle by cleaning it with the atomic method. This is how the filament was after taking out rapidly at 90C
I did it several times.
Here are some videos.

Thanks,
