Hi,
the Atomic method worked and I wanted to share the settings I used:
- Chose the replace material option and cancel it when filament is out.
- Remove the bowden tube
- Heat the nozzle to 260C
- Push strongly a piece of ABS for like ~5sec.
- Keep a small pressure, just to be sure that the new filament will stick to the blocked piece in the nozzle.
- Cool down to 120C
- Pull hard
- resuming printing
