@engikeneer ahh that makes perfect sense, it's 0 now and at layer 25 so the superpinda isn't sensing the bed any more. Thanks

Hi there,

Has anyone got a baseline setup for an Ender 5+ to share?

I'm coming from Marlin so lots of new stuff to learn, so just looking for a little shortcut if possible

In the online configuration tool I can't see how to setup dual-z axis, do I have to set that up manually?

Thanks

@Norder thank you for the help, greatly appreciated.

What does that number mean and why is it in red, seams like something is wrong?

As I have no reference, can someone help me understand what the graphs are telling me?

39Hz is that pointing towards some specific part that causes it?

Amplitude, what it a lot and how little is great?

I've read through the documentation, installed the Plug-in and done some tests, but I'm not fully understanding what I should expect.

My printer is a RatRig VCore3 (400x400x400) and I'm using a 6HC with SBC and a 1LC toolboard, bot the the latest stable firmware.

This is how I have the accelerometer setup, and I think I got the orientation right.
M955 P121.0 I16

(this is looking from the front and 0,0 is in the front left corner)

I've run several runs and they always come out slightly different, sometime rather different. Here one of them, without any IS active.

From my understanding of the documentation I shall determine any large peaks and if more than one set the "Shaper center frequency" in the middle. First of all I'm not sure what would qualify as a significant peak, in the previous images I can identify three that stands out, two on the Y axis and one on X. Though I'm not sure I should allow for more than one peak per axis?

Next up is what I think is the best result (I manually activated one IS model at a time and recorded a new motion profile.
This is the result with ZVDD active at 56Hz and 0.1 damping factor.

The peak amplitude goes from 0.029 to 0.016 which is relative terms seams great, but I have no idea if in reality it is? Or what's considered a great, ok and bad amplitude value?

Also these peaks, do we have any clue what causes them?

What does Damping factor do, I assume it alters how much impact the filter will have? How shall it be used, what are resonable values?

One last thing -- I haven't used Klipper myself but I've seen videos of what I think are people doing IS tuning and in those videos the printer tested a lot of different movement speeds, everything from really slow to so fast you couldn't even see, only hear the motion.
But I might have misunderstood and that was intact some other type of test?
Anyhow I was just a curious to why RRF does a single scan and not multiple and take a average with any outliers removed?

Sorry for the long post, I hope someone can help me understand and learn a bit

@dc42 wired, I fiddled a lot with it yesterday and didn't get it to work. I'll revisit it tomorrow.

Regarding the range, the documentation refers to two ranges, 0-255 and 0-1, what's that about and how can it be used?

Is there a way to gracefully shutdown the SBC from DWC, maybe a built in G-command or a way to trigger a shell script/command on the SBC itself?

@dc42 makes sense, thank you for explaining that. Is there a way in RRF to define the usable range? Or can I only change the minimum/maximum speed it ranges between?

@droftarts I have gotten it to work, turned out the initial wiring I had was correct, but I had to lower the Q value for it to work. I'm now at Q10600 which gives me around 2500 rpm minimum.

Now I'm trying to figure out how to fix the flat spot I have in the % range, 1-10 is completely flat at 2500, not until 11% it starts climbing.
I've played around with M106 Lxx but that only increases minimum rpm and have no affect on the flat spot.

@droftarts this is how I have it wired right now, first attempt had bluw/yellow swapped.

@Reine 6HC on 3.4.5 and 1LC on 3.4.4.
