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.

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.

Hm. Yep, saw this video. Is it bad cause of second peek?
Rigattoni
Rigattoni•347d ago
yup

Maba_Kalox•347d ago
Hm. What could be reason for it? Did not find explanation in the video.

@Helge Keck sorry to bother you, but any ideas about second peak on Y?
