ExtrudoWhy is my 3D print ringing / ghosting?
Ringing / ghosting is usually caused by vibrations from fast direction changes are shaking the frame slightly, echoing into the print surface. Faint wavy patterns repeat on the surface near sharp corners or edges

How do I fix ringing / ghosting? Step-by-step
- 1
Reduce print speed and acceleration
Lower your acceleration and jerk/junction settings by 20-30% and reprint a test with sharp corners.
Done when: Wavy patterns near corners are less visible
- 2
Tighten the frame
Check and tighten all frame screws and belt tensioners — a loose frame vibrates more.
Done when: No wobble when gently pushing on the frame by hand
- 3
Enable input shaping if available
If your firmware supports it (Klipper, some Marlin builds), run the input shaping calibration routine to cancel out resonance.
Done when: Input shaping values are calibrated and saved
