Swapped EVA -> RatRig toolhead and massive resonance spike
I swapped my eva toolhead to a ratrig toolhead recently and changed from an lgx lite to an orbiter v2.
During the recalibration process i started noticing that a few of the frequencies had really bad resonance at double the oscillating frequency.
Most of the frequencies were fine, but oscilating at 90hz for example, I get a really bad resonance at 180hz.
Any thoughts on this?

I'm fighting some similar high frequency noise on my RR Toolhead 1.0 with orbiter 2. I'm also using a beacon as my accelerometer.
At this point I've replaced everything but the orbiter and the hotend. So maybe it's one of those?
@OldKingHamlet i've pretty much came to the same conclusion.
the orbiter seems to want to rattle when oscillating at around 40hz-50hz
I did find a loose screw on my rapido that was rattling at high freqs.
so... on a whim i disconnected my orbiter and rapido and ran thru the belt tension test again
i think the 125 spike here is due to my ebb toolhead wobbling a bit since its not braced by the orbiter, but it does show that the majority of the frequency spikes above 150hz go away
Oof, is that screw on the heating element? I guess I know what I'll be doing over lunch tomorrow
I'm also tempted to check out the orbiter 2.5 upgrade, but I don't know if that'll change anything.
