/diy/ - Do It Yourself

Klipper bros, I'm trying to set resonance compensation on my modified Ender 3 Pro.
While the results I got on Y axis are amazing, I can't get noticeable improvement on my X axis. The frequency should be around 36 Hz by my measurements of the bands, but it all looks not great and same on v.high accelerations. I understand that in realistic printing this will be less noticeable, but I do want to dial this in.
I even resorted to finding the frequency by sweeping from 0 to 55 with a tower.
Maybe it's the limit? I've tried zv, mzv, ev shapers, no difference.
