Can't equalize belt tension
I have such graph currently, if I try to tighten lower belt, my gantry moves out of square(when I move x gantry to the front, it does not reach idlers on both side) and first peak of lower belt becomes higher.

so it becomes something like
What I did trying to fix it:
1) check belts lenght - they are equal (measured by teeths)
2) followed new guide for squaring the gauntry from dozuki
3) reassemble entire frame
or that graph is fine, and I should not care to match peaks?
From my POV the first graph looks good.... yes there seems to be something loose at the hotend, but this is something you can live with. What I would do to get the X-gantry is:
Loosen both sides of the screws which are holding the X-Gantry to the rails.
Move the gantry to the front and make sure that bothends are parallel to the front and tighten the bolts again. Make sure that they are tight.
Check again after tightening the bolts.
More important than the belt tension is the shaper graph.
yep, that is exactly what is described in https://ratrig.dozuki.com/Guide/10.+X-Axis+Gantry+Alignment/209?lang=en

@rigattoni how good is it? 8)
or bad xD
Y is quite bad. --> https://www.youtube.com/watch?v=M-yc_XM8sP4

How to Read and Analyze Input Shaper Graphs Generated by Klipper
This video is supposed to be a brief overview on what the input shaper graphs can tell us. It is the first video of a series of videos which will give a more in depth view on the kinematic system and input shaping in Klipper.

Hm. Yep, saw this video.
Is it bad cause of second peek?
yup
Hm. What could be reason for it? Did not find explanation in the video.
Sorry, never seen such a graph before. 😦
@Helge Keck sorry to bother you, but any ideas about second peak on Y?
not sure
