Help me understand what my Input Shaper graphs are telling me
First of all, unlike most people here I'm using Duet hardware with RRF, so these graphs will be different but hopefully someone can still intemperate them and get something out of it.
The image with an maximum amplitude of 0.030 is without any IS active, the other is with "ZVDD" on at 56Hz.
Can someone read something from these graphs?...
strange horizontal Y pattern
I have a strange pattern in horizontal y, will it be related to the graph on “Y”?
I know that the horizontal pattern is due to the overlapping of the fill, ignore that, I mean the horizontal pattern.

Tension graph core 3.1-500 okay?
Core 3.1-500 - is this tensioned well in terms of peak and similarity?
Before and after impute shaper shows no change
I do not see a difference after running impute shaper. Might i be missing something in the cfg?
Graphs for V-Core 3 400 original Belts
Hello... Actually, my printer is running quite well... I've done the tests anyway and I'm wondering whether the values are good or whether I need to optimize something... Unfortunately, I can't read the graphics properly , they seem very confusing to me... 😅
Resonance calculation attributes Y resonance to Z in graph
Hello,
I am measuring Input Shaper using the "Generate Shaper Graphs" script.
The results are below....
I can't resolve my vibration issues. Can someone help?
EDIT: I did a lot of testing and my issue has shifted. Explanation is a few comments lower (or here: https://discord.com/channels/582187371529764864/1084813725279715459/1085521418235678731)
Hello,
thanks to RatOS 2.0 i tested the linear movement analysis plugin and noticed very high vibrations on my Y axis.
I believe this causes a wavy pattern on my prints, which are only on Y sides....
I think I'm ok?
I do have questions on the Frequency responses graph as to which line is the y and x and also, which belt is even considered y and x on the V-Core 3?
How to evaluate my belt and resonance?（V-core3.1 300 Enclosure2.0）
Hello mates,
What do you guys think of my belts and resonance?...
Good belt tension graph for vCore 3.1 400?
Hi everyone ... Im new in this world of Frequency graphs. I think this Graph should be okay but maybe someone can help me and can take a look of it. Is this Graph good or you can see some issues:

Keep adjusting or leave it alone?
VCore 3.1 500 w/ v2 enclosure, based off what ive seen posted before I should stop adjusting and let it be correct?
Loose bolt or something? VCore 3.1 300
Hello mates,
What do you guys think of my belts and resonance?
I think I might have a loose bolt or something.

V-core 3.1 400 full metal mod. Looking kinda clean.
Should I touch anything or just leave it as is? I am kinda happy with how it looks and dont want to mess up something.
V-Core 500, Y-Resonance, Duet RRF
Hey all, i have all but eliminated the resonance in the x axis, my belts are equally tensioned measured via the tensioner tool. All thats left is some minor ringing in the Y which if i can fix i would love to. I use Duet so i have not been able to quite compare my readings with you all but if there is anyone who can help me decider any issues in my vibe tests id appreciate it
[v-core 3.1 500] Further Tuning Advice
I have spent the past couple of days resonance tuning my newly-built VC3.1 500 and I do believe I have gotten my belt tension graphs and resonance to be decent at this point.
However, I have noted that the belts do still slap a bit against the frame at their peak resonance frequency and was wondering what the optimal solution to actually verify that the absolute belt tension is about what it should be.
After doing some tightening of both belts, I have been able to generate the attached graphs. I was wondering if it is worth chasing any further tuning, or just going with what I got, using MZV with the provided profile and playing with acceleration limits from there....
VC3.1 500 issues. FMMM and Extrusionless X
I have recently built my second VC3.1 500 and have added FMMM and an extrusionless X. My resonance and accelerations are quite a bit lower than the first machine I built and I'm scratching my head as to why.
The tool head doesn't move at all when I manually move the gantry forwards and backwards, the belt does walks up and down a bit on the pulley but it doesn't seem to be chewing it up. Checked all bolts and tried to keep the umbilical cables tight. They're in a nylon sleeve with 1mm piano wire. The machine is sitting on a table but it's pretty sturdy... I will try and put it on the floor and test but anything else I should look in to? Thanks!...
Resonances on y axis (v-core 3.1 300) are horrible, it's driving me nuts.
I've been trying to tune my belt tension and get rid of resonances for a week, and I feel like I'm getting nowhere. I managed to get the belt tension to a point that I thought was "good" , and then ran the resonances graphs for input shaper. X doesn't look too bad to me, but y is an absolute mess. I've checked for loose screws, and anything that may be vibrating, but I can't find anything and I'm getting desperate. I would appreciate it if anyone more knowledable than I would lend me a hand, as...
