Hi! I am currently seeing some issues on my voron while testing resonances. I just wanted to confirm my interpretation of the results, that my printer suffers from some kind of binding on the B-Belt or if there is something else at play?

#

Here the same config but measured on the x and y axis

you a and b belts are not tensioned the same. That needs to be fixed before you move on to x and y.

#

I recommend installing frix_x shake and tune

see page 7 on the pdf - graph on the left for recommendations

they are tensioned the same as far as i can tell. both resonate at the recommended 110hz

i did find a place where the b motor belt did rub at something and at the same tension I got this result ( look at blue and yellow). it improved just slightly unfortunately... so it was for sure rubbing but I still get quite low x-accel for whatever reason

how are you measuring absolute belt tension?

#

in either event I would rerun input shaper. Think about installing shake and tune
