But it seems like the machine doesn't like it overall as it's way way louder and motors sound angrier 😂

To a point. There's still an involvement of Injecting enough energy to out scale any noise.

So in simple terms amplitude in 2 dimensions. It's measured here in decibels too.

Well every frequency is made up of multiple different frequencies. PSD is the sum of all those frequencies. In 3 dimensions there's a good few frequency peaks across the range with an averaging peak as the "main" in 2 dimensions

But yeah. It seems like it's just the Eva toolhead wobble in the Z component now that I re look at the graphs. Secondary spike remains the same. ( This is very different than my previous tests as the secondary spike always seemed to scale with the main. )

The graph can be read as range of frequency on X and amplitude of frequency Y.

PSD is amplitude of power per frequency.
