How to Fix Stringing / Oozing

Step-by-step fix for stringing / oozing on Bambu Lab printers including X1C, H2D, P1S, and A1.

How do I fix stringing / oozing?

1
Increase retraction distance by 0.5mm increments (start at 0.8mm for direct drive). This is the single most impactful setting for stringing.
Setting: speed.retraction.length
2
Lower nozzle temperature by 5–10°C. Over-heated filament is more fluid and oozes during travel moves.
Setting: others.nozzle.nozzleTemp
3
Enable "Avoid crossing walls" in Quality > Advanced. This keeps the nozzle inside the print during travel, preventing external strings.
Setting: quality.advanced.avoidCrossingWall

Pro tip: Select "Good Cosmetics" above — it enables wall-avoidance and seam-hiding settings that also reduce visible stringing artifacts.
