Print Issue: Print continues with no filament feed

[Jesi15]

Have you attempted a cold pull? There are a few threads discussing clogged extruders causing print failure, here is one:

A350 printing "into thin air", no filament extruded

I can’t speak to the blockages you’ve had, but unloading filament will normally leave a small plug of filament like your second picture shows. Does doing a cold pull remove the blockage?
