Over dampening?
Was trying to figure if the frequency graphs look good or not and what shaper to select. Based on what I have read: if the Y peak is bigger than X, it means that it's over over dampening. Is it generally always true or does it depend on 3d printer design?

This looks perfect
I would go with mzv

Thanks for the look. In general, does the amplitude / power spectral density have anything meaningful impact on input shaping or print quality to that matter?
a thin sharp peak is good and something between 5e4 and 1.5e5 is normal
usually when your peak is thinner, the amplitude is higher
if it's all over the place, the amplitude is usually low

Good info, thanks!

This is after adjusting workbench legs where the printer sits. I noticed that one of the legs was very slightly off the ground and wobbled a bit. I guess the magnitude of the change wouldn't affect anything here.

These are from printer sitting on concrete floor. Strangely they are worse? So having some flex on your table is better? 😛
