First steps with my resonance
Hi everyone. I am trying to tune my v-core 400 and also the accel. could you kindly guide me in a direction? These are the two input shaper graphs. From my understanding there is a huge gap between x and y because the peak of X is at around 62Hz and the one of Y at 42Hz. Is this a belt tension issue?

This video is very usefull in understanding these graphs:

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.

You can check belt tension equality with a mobile phone and a spectrum analyzer application, as described in this document:

Finally, movements in Y have to move more mass than movements in X. Therefore, the resonant frequencies of the Y axis tend to be lower than the X axis. On top of moving more mass, movements on the Y axis also have to move 2 rails in stead of 1 - which means more dampening.
Overall though, looks pretty decent!

Thanks for the "literature" will look into it and will try to understand it. I will come back for further questions if thats ok.
That's always ok 🙂

Thats motivating!
you can do a belt tension run as well, that will tell you how equal the belt tension appears to be

Is there a already known alternative for iOS? Suprizingly there is no Android device in the house anymore
unfortunately I wouldn't know about that, all android here

Ok i will check 🙂 Thanks so far and until later most probably 😅
