Quick diagnosis
Reduce PETG stringing by tuning temperature, drying filament, retraction, travel speed, and cooling without weakening layer bonding.
Likely causes
- Wet PETG
- Nozzle temperature too high
- Retraction too low or too high
- Slow travel moves
Step-by-step fix
- Dry PETG before chasing slicer settings.
- Lower nozzle temperature in small 5°C steps.
- Increase travel speed so the nozzle spends less time moving over open air.
- Tune retraction carefully; too much retraction can cause clogs.
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.
