How to Fix Ghosting / Ringing

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

How do I fix ghosting / ringing?

1
Reduce print acceleration to 2000–3000 mm/s². Ghosting is caused by vibrations from sudden direction changes — lower accel = smoother motion.
Setting: speed.accel.normalPrinting
2
Slow outer wall speed to 100–120 mm/s. The outer perimeter is what you see — printing it slower eliminates vibration artifacts.
Setting: speed.layers.outerWall
3
Check belt tension and tighten if loose. Mechanical play in the motion system is amplified at high speeds and causes ringing patterns.
