Ill answer here about graphs the new graph looks much better of course second peak you can ignore its not acceleration related vibrations, it just bleeds in still wondering, what this peak in y is though that shouldnt really be there

yeah that confused me too I thought my mount was pretty solid...

its ok that it shakes in y a little bit when it fully resonantes but we can see at the graph above with the belt a bit loose, that it is a peak by its own your peak in general is very wide in the latest graph too wide, imho (hence why tuning the dampening ration helped you) but shaping this wide will also increase smoothing

well, i didn't do it yet. Was just trying to figure out how to So you think it's still really a hardware issue?

yep, those belts are way too tight now and there is a good chance, they are already strechted out at this point

Oh yikes, I tightened them thinking maybe that was the issue before I found the loose screws So... 1. loosen the up and see if that helps. 2. If it doesn't it's probably time to buy some new belt ?
