VC4 500 IDEX IS Y-axis

[unborn goblet]

Just upgraded to the Toro titanium tube to fix my first layer issues and started re-doing the belt tension process. Used the GATS system to set tension with about 4.5kg of tension and got the following input shaper graphs on my y-axis. They look pretty awful, but all the x-axis charts look pretty respectable with MZV recommendations. I am at a loss for what may be causing it. I've traced belt paths, made sure they're centered on the idler stacks and pulleys, made sure the gantry is square (confirmed with beacon calibration), tried high tension, tried low tension, added zip ties to the umbilical, removed them, relocated them...whatever this is seems like something big that I am missing. Any ideas?

have you used 4.5kg on both x and y? i got better graphs with more tension on y than x

Yes, I used the same weight on both the core xy and hybrid belts. I'll put a little extra tension on the hybrid belts and see if there is an improvement.

keeping an eye on this one too cause im having issues with Y as well. ive just tighted the hybrids more and will give it another go to see if it improves

Still struggling with this unfortunately. I completely relocated my filament spools to the top of the printer which pretty drastically changed the umbilical setup, but still getting poor performance on the y axis resonance. I've been trying to use the live analysis tool as well, but I can never find a spot on the printer that improves the peaks I'm seeing. This is getting pretty discouraging.

i said screw the IDEX and went down to a hybrid over the weekend and nearly had it perfect in a night of playing with the belts. ill revisit the IDEX setup after i print on the hybrid for a bit and feel encouraged about the printer's functionality overall.

@unborn goblet This looks like binding.

How does the y sound when you do the rensonance
