belt tension results, weird spike at 50hz on 1 belt every time.
Keep getting results like this no matter what i do with the belts. Whats with the weird spike at 50hz? The rest seems very good but nothing seems to tune out the spike.

that's how the graphs should look like, i wouldn't call the one you posted really good.
I think for a start your belts are too tight
What size printer?

If axes shaper comes out well, your belt graph doesn't matter. Seems like you almost have them at equal tension. Worry about the spike if IS looks wonky
it matters, it's a lot easier for the input shaping to reduce one sharp peak, than a jagged mess with 100 hz range.
if the X,Y graphs look like a mess it means there's hardware problem that need to be addressed, both for print quality and longevity of the mechanical parts.

Hence "if axes shaper comes out well"
Ltr
well i've read it other way around 🙃
although it's impossible that X, Y graphs look good if the belt tension one looks like that
