Strange graphs after adding beacon probe
The only thing I can think of that could cause movement in the Y-direction when vibrating in the x-direction is if there some kind of dampening or binding in the belt path for one of the belts.
If one belt moves slightly more than the other (or just stretching? motor-skipping?) then that would give a slightly diagonal movement instead of pure side-ways.

Strange graphs after adding beacon probe
In the X-axis IS graph it seems like both x and y axis are vibrating (red and green curve). Is there something loose that could make the beacon vibrate in the y-direction when the carriage vibrates in the x-direction?

Resonance problems after upgrading with Beacon and EBB42
Good to know. When I did the upgrade I also mounted the volcano adapter on the hot end, I didn't have that before.
That adds a bit of extra length from the mounting point at the rail carriage.
Perhaps it's just the extra weight (beacon + cable) that makes the whole print head wobble in the Y-direction?
Just wiggling it by hand I can definitely feel more swing in the Y-direction than in the x-direction.

It might be. The holder is quite wide in the x direction so it will be much more rigid i x direction (thus no extra peak in the x-graph). But in the Y direction it’s quite thin and only supported on the lower section.
