Ratcube Ringing on Vcore4 hybrid
I must not have my belt settings correct as I have some pretty bad ringing on the Y axis, some noticable ringing on X axis as well. Any tips on where to start? Tightening my belts?

Some more background info would be helpful. What did your belt graphs look like? Can you post your shaper graphs? Is this coreXY or hybrid? Did you take the recommended shaper settings and put them in your printer.cfg? Did you take the max acceleration settings and add them to your slicer?
I have a ratrig vcore 4 500 Hybrid. I've attached my shaper graphs. Also I have the following settings in my printer.cfg: [input_shaper]
shaper_freq_x: 10700
shaper_type_x: mzv
shaper_freq_y: 5700
shaper_type_y: mzv
For my slicer I set petg speeds to 40mm/S and acceleration max were all capped at 5700 or slower
Config should be....
you have the acceleration numbers in the config instead of the frequency. The input shaper can only deal with the lower of two accelerations so you should set your external perimeter acceleration to be a max of 5700 accel. The other max accelerations you can stick back up higher as you wont see them in a print since they are inside, etc
Also is that belt tension graph with or without the hybrid belts? If its without them it seems strange.
What slicer and version are you using as well?

Oh man thanks chicken, good catch! The belt tension graph is with hybrid belts installed. I am using the latest version of prusaslicer
Cool see how it goes with the updated settings
Definitely a great improvement when I use the correct frequency! Here are the new pics. Is this about as good as it gets? I still see some small traces of ringing. Old cube on left, new cube on right.
