Question Ghosting after Input Shaper - Resonance Issue?

[thebigone2087]

I need major help.

I upgraded my Trident with CANBUS and a number of other things and ran pressure advance and input shaper (via SHAPER_CALIBRATE) and I have noticed some major ghosting on my prints. It was suggested I run the axis independently for input shaper then look at the graphs. Well... X looks fine... Y is another issue. The issue on TOP of the graph, is I don't know what it means or how to fix it. Anyone care to help out?

I am learning this process, but I am currently doing it old school with the test prints. There are a number of shaper types. This link explains the differences. You may want to run a test print and see if it shows the same issue on the two axes. https://github.com/Klipper3d/klipper/blob/master/docs/Resonance_Compensation.md

I'm no expert on this, but I would start with checking every screw and make sure none are loose. Then I'd check all belt tensions.
