Step-by-step fix
- Heat the nozzle to the filament temperature.
- Push filament manually until it flows.
- Cool to the material pull temperature.
- Pull firmly and inspect the end for debris.
What to check before changing more settings
Only change one variable at a time. Save your current slicer profile before testing, use a small repeatable test print, and compare the result before moving to the next adjustment.
