First Graphs from my Vcore 400
Hi, i have spent the last few days setting up my Vcore 3.1 400. Before I start calibrating and printing, I would be interested in hearing what you think about my graphs. Is everything okay so far?

VC 3.1 400 Belt tension
Hey Guys,as u can see my belt tension results are completly useless,the zip contains every measurement from today (belt tension and IS).im using the adxl from the ebb 42.Wire harness is loose not fixed with for example piano wire,and fmmm mod incoming for better troubleshooting.Appreciate any help u can provide

Starting off on my V-Core 500
I am just finishing off building my V-Core 3.1 500x500 with enclosure.
I am getting these resonance results. The X looks pretty good but the Y is very low.
2 questions:
1. Is this ok for a stock 500x500 Y acceleration?
2. How do I set this in my printer.cfg? do I set a separate x & y max acceleration & max deceleration? or do I have to limit the whole thing to 3K accel?...

LayerShifts
i've been experiencing some layer shifts on my relatively new 400x400 build. this is my input shaper graph. should I assume that the lower tensioner is just too loose? i saw that most of the peaks were identical, just not the highest one. Does that mean that i need to tighten the lower belt?

Enclosed VC3.1 300mm Belt Tensioning
I've been trying to make sense of the belt tension and resonance graphs for an enclosed VC3.1 300mm I just made. It has the FMMM, Motor Decouple-Damper, an EBB42 and it's sitting on the floor (on floor tiles, so maybe that could contribute to my problems, though it does not have any noticeable rocking). I've watched the youtube video that is recommended everywhere for
how to read and analyze input shaper graphs...
, and took a look at a fair amount of posts/messages here, but in trying to follo...
what is this extra peak....
belts arent binding anymore. got good belt resonance graph. but still have this blue peak on my Y resonance. while X looks pretty good.

XY matches, but....not tight enough? maybe?
is it possible to tell from a resonance graph if your belts are tight enough? here's my graph. you'll see that X and Y are pretty much equal. But my prints lean rather heavily. As you go up in Z, it seems to shift in both X and Y directions. I wondered if maybe my belts simply aren't tight enough?

Bad input shaper Vcore 500
Anyone have an idea? I've been thinking about this for a few days now... Neither Zv nor Mzv helps on the Y axis. The X axis is probably OK. Speeds are 100 fastest, acceleration 3500. Vcore 500

pressure advance values not respected in printer.cfg
The printer isn't using the set .3 pressure_advance setting

Shaper calibration: Fans on or off?
Hello.
When running shaper calibration, should the fans be on "as normal" (Ex: Print fan @ 100% and heatbreak fan on) or should they be completely off?
I found a reddit post from years ago about it, and there was a response that recommended them being on, but I haven't seen it discussed here or on any official klipper posts...
Need help interpreting graphs for 400mm V-Core 3.1
This is my first core-xy printer and even after watching the frequently recommended YT on these graphs, I am not sure how to interpret them. From that video, I get the feeling these graphs would suggest some binding on my x-axis. But I cannot feel that binding myself when i turn the motors off. Is there something else i should look at?

First steps with my resonance
Hi everyone. I am trying to tune my v-core 400 and also the accel. could you kindly guide me in a direction? These are the two input shaper graphs. From my understanding there is a huge gap between x and y because the peak of X is at around 62Hz and the one of Y at 42Hz. Is this a belt tension issue?

Trying to tune Vcore 400mm
I attached the ADXL345 accelerometer to Vcore 400mm and ran the macros in RatOS for belt tension and input shaping.
I gather working on belt tension should be done first, but my graph looks nothing like others, so what does it mean? Too tight, not tight enough?...

Is this okey?
Vcore 3.0 300x300x400 with openfront, eva 3,ballbearring idlers, 4028fan, ebb36(little bit tilted, need other standoff)
I´m thinking, x belt to tight,y to lose or am I incorrect?...

I dont rly understand this
On my belt tensioning the second peak is completly missing,the belts are exactly the same tention for the first peak.x and y is is kinda weird since x is lower than it should be imo.I'll Appreciate any help
