BTT SFS v2 Motion Doesn't work
I ended up ordering a new BTT SFS v2 and it works. I double checked the voltages on the new one and it was as I expected: as I move the filament, it switches between 0V and 4.4V every few mm. There must've been something wrong with the electronics of the old one. I have processed an Amazon return for it.
I tested both filament runout and filament jam capability of the new one, and it works fine with the following in my printer.cfg:

Yes, it an encoder wheel with holes and IR tx/rx around it, which changes the signal every 2.88mm of filament. If you set detection length to 6(mm), then RatOS expects to see at least one signal flip/pulse every 6mm of filament it thinks it's feeding which accommodates some slack in the bowden tubes, etc (but either way will see zero pulses if it's jammed because the wheel isn't spinning). It's surprisingly simple at the end of the day.

BTT SFS v2 Motion Doesn't work
When everything is connected properly, the voltage between GND and SIGNAL oscillates between 2.68V and 3.18V as the filament moves. I guess still not enough to switch the state of signal pin on the Octopus board

I'm fairly certain it's supposed to switch voltage ever 2.88mm of filament movement. But maybe this is defective, because that's not enough

Is the 2.9V switching enough for the microcontroller to detect? I guess not since the Octopus Pro board is not detecting the change

Seems kinda obvious in hindsight.
RUNOUT wires goes from 0V (empty) to 3.77V (filament present) ✅ MOTION wires, oscillates between 2.4V and 2.9V as filament moves ❌

I forgot to mention that it pause immediately on starting the print, then when I resume, it will continue printing to the end with no issue. However, it does not detect the "jam" if I manually stop it from feeding.
Also, in the Mainsail UI, it will show either "empty" or "detected" for that particular sensor, but doesn't change when the filament moves. I was under the impression it should switch every 2.88mm

Shaper graphs have different peaks for Y and Z
Gonna see if the Toro3d guy will send me a new one. I weighed the whole X-axis before putting it back in:
Old X-axis: 610g
New X-axis: 270g
About 40% of that weight savings is the linear rail. I'll probably just have to suck it up and go back to the old rail for now.

The accelerometer is mounted on the standard mounting holes on the front-top of the EVA3 toolhead (upper left in the video).
In the clip you can see how insanely bad this problem is. I'm hardly applying much force. The glide block is clearly rotating with the toolhead. The bearing balls must be the wrong size or something.
So my hypothesis is: the center of mass is not centered on the glide block, then the Y-oscillations will induce rotations about the X axis. Given the position of the ADXL, that would probably look mostly like Z movement.
I won this assembly in a discord raffle from Toro3D. This one must be defective. This is the first time I've tried assembling the gantry with it. Haven't tried printing anything yet. I suspect this will cause major problems as you suggested.

Shaper graphs have different peaks for Y and Z
I just squared it up and tried to equally tighten the belts, which got me to this point. Nothing feels abnormal to me.
I think my belt chart does have both peaks, they're just pretty close so I think they merged into (almost) one, due to the extra-light X-axis, which raises the frequency of the Y-axis test peak to be closer to the X-axis test peak. At least that's my intepretation of it.
I realize now I should've marked specifically what I'm looking at on my chart: "Y-axis test graph" that shows different peaks for measured Z-vibration (blue) and measured Y-vibration (green). The peaks are distinct, and the measured Z-vibrations (blue) is much bigger than the Y (green).
I think that means the toolhead is moving up and down, or rotation around the X (I posted here looking for feedback, but I think I'm figuring this out as I type). I did just confirm that the print head has quite a bit of rotational play about the X-axis. I think that explains it. This linear rail has a serious problem!

Is it possible to just download the latest firmware and flash manually? I'd like to try that before doing a full reset of everything.
