Starting off on my V-Core 500
I am just finishing off building my V-Core 3.1 500x500 with enclosure.
I am getting these resonance results. The X looks pretty good but the Y is very low.
2 questions:
1. Is this ok for a stock 500x500 Y acceleration?
2. How do I set this in my printer.cfg? do I set a separate x & y max acceleration & max deceleration? or do I have to limit the whole thing to 3K accel?
I am running klipper not RatOS.

graphs look good, on big corexy printers Y recommended acceleration is significantly lower than X, as long as the graph is clean it's just how it is.
mainline klipper doesn't support separate X and Y accelerations.
so set inputshaper values add to your printer.cfg
you shouldn't use ZV shapers, they work for very narrow band of frequencies and there's good chance you'll see ringing just because frequencies will change slightly somewhere in the huge build volume. MZV has pretty much no downsides, slightly more smoothing, but also wider band of frequencies it cancels.
as for accels, you should configure them in your slicer profile, slicer overwrites accels from klipper config anyway. i'd start with recommended Y accel for external perimeters, for rest of stuff you can go higher.
after week or so, i'd check the belt tension again, because stuff will settle in. after that it's smooth sailing :-)
Thanks for that.
I think I might need to work on the belt tension as I am getting vibration noises when the toolhead moves in some diagonal directions.
Good to know about the ZV & MZV so thanks for that. I think I will set it up with lower 3k for perimeter & higher for the internals so.
