Stringing is usually solved by checking filament dryness, lowering nozzle temperature in small steps, tuning retraction, increasing travel speed, and avoiding unnecessary combing or crossing moves.

What this page helps with
stringing, wispy hairs, cobwebs between parts, oozing, retraction problems.
Use this as a landing page first, then jump to the most specific detailed guide below.
What it looks like
- Thin hairs between towers or small features
- Webbing across open areas
- Clean outer walls but messy travel gaps
- More strings after changing filament brand or material
- PETG or TPU strings even when PLA looks clean
What usually causes it
- Nozzle temperature too high for the filament
- Wet filament pushing steam and ooze through the nozzle
- Retraction distance or speed not matched to the extruder
- Slow travel moves across open gaps
- Pressure advance or flow not calibrated
Do this in order
- Dry or swap the filament before changing every slicer setting.
- Print a temperature tower and step down until strings reduce without weakening layer bonding.
- Run a retraction tower or Orca calibration test for the actual filament.
- Increase travel speed and reduce unnecessary travel across open spaces.
- Check flow rate, pressure advance, and nozzle cleanliness if stringing remains.

FAQ
Fast answers
What should I check first?
Stringing is usually solved by checking filament dryness, lowering nozzle temperature in small steps, tuning retraction, increasing travel speed, and avoiding unnecessary combing or crossing moves.
Should I change many slicer settings at once?
No. Make one controlled change, test again, and save the working result in Profile Vault. Random setting changes make print failures harder to diagnose.
When should I use AI Doctor?
Use AI Doctor when the symptom is unclear, when the print failed in multiple ways, or when you want to connect a failed-print photo to the right guide path.
