Stringing is filament left between features during travel. Temperature and retraction can contribute, but wet filament, contamination, material, and travel paths can look similar.
Start from a known profile
Prusa recommends its factory preset for the supported printer and material. Retraction is machine-specific: its Bowden MINI preset uses a longer value than its direct-drive machines.
Controlled sequence
- Confirm the printer, nozzle, and filament preset.
- Inspect and clean the nozzle using the maker's procedure.
- Check for moisture symptoms.
- Run a small temperature calibration within the product range.
- Adjust one retraction or travel variable at a time and record it.
