Stringing — thin strands left between separate parts of a print — is a normal result of molten plastic oozing during travel moves. It is rarely caused by one setting alone.
1. Nozzle temperature
Lowering nozzle temperature by 5–10 °C reduces oozing. Drop in small steps and check layer adhesion as you go, because going too low creates weak parts.
2. Retraction settings
Retraction pulls filament back during travel so it stops oozing. Bowden setups generally need longer retraction distances than direct-drive extruders. Increase distance and speed gradually rather than jumping to large values.
3. Travel speed
Faster travel moves give the material less time to escape. Enabling "avoid crossing perimeters" also keeps travel moves inside the part where oozing is hidden.
4. Moisture
Wet filament is one of the most common and most overlooked causes of stringing. If stringing appeared suddenly on a spool that used to print cleanly, dry the filament before changing any settings.
Order of work
Dry the filament first, then tune temperature, then retraction, then travel. Changing several variables at once usually makes it harder to tell which one helped.
