V-Core 4 500 IDEX resonance
After doing a full resonance test I am left with these graphs. Are they they as expected?

IDEX 500 Y resonance
I want some feedback on the resonance on Y of this IDEX 500. We use this machine in our business and we don’t aim to have the most crazy graphs but needs to be reliable and well calibrated.
strange noises on y (vCore4 IDEX 500)
Hello, I just finished my build and i am a bit concerned about the rattling noises on the y rails. If you check out this video, you can clearly hear the sound. https://cdn.discordapp.com/attachments/1223286652949106748/1351344121192775853/76394870036__BCFB4BBD-F1A2-47C7-81B4-951331BF2215.mov?ex=67dab189&is=67d96009&hm=689e4d511cd0e2a9ab8777330d20c06b4b9b19e2952d993d8cd67852d1dcc630&
you can also see it in the input shaping graphs. x is clean, y is not.
I did everythign according to the build guide including cleaning the rails with isopropanol and lubricate it with high performance grease for fast rotating bearings.
I hope to find some help here....
big peak on 35hz on y axis help :/
Hi, i am tuning my v core 4 400mm and i am stuck with problem that my gantry is shaking like crazy on around 30-35Hz which gives me horrible accelerations . I used real time analyzis to test that frequency and i found the carriage is shaking the most , if thighten the belts then whole gantry is shaking.
Y axis funky, X axis perfect
So, V-Core 3.1 w/ Toolhead 1.0 and Beacon.
I have a lightened gantry and metal gantry mounts installed. I used to have FMMM and AliExpress "heavy duty" bearings installed too but I removed both in my troubleshooting.
All motor mount and Toolhead parts are printed in ASA-GF. Belt length is literally identical down to the tooth....
My Y belt tension seems unusual
any suggestions on the Y's
running a vcore4 400 IDEX
I've checked all the belt paths and they seem to be in check with proper tension and no mater what i try they dont change on the graph....
Struggling with Y Calibration
Just built a V-Core4 500 IDEX and have been going through the belt tuning. I have looked through other posts her an attempted to tune the belts, but it seems that I am doing something very wrong.
Even more confusing, a fine grey-ish powder has begun to appear in the lower left motor box and I can't figure out why...
Measure CoreXY Belt Tension
Dear community,
I'm trying to get my COREXY tension graphs for an IDEX system.
Under the calibration TAB when I select MEASURE COREXY BELT TENSION, I can only select Toolhead 0 and not 1.
So I am only getting the graphs for my left belt....
Resonance problems after upgrading with Beacon and EBB42
I recently upgraded my stock VC3.1 400 with a Beacon and a EBB42 toolboard. but after this I can't get back to decent IS graps anymore.
In the X-axis IS graph there's a huge peak at the end of the measurement that did not exist before.
In the Y-axis IS graph there an additional peak at ~67Hz with a wide tail at the higher frequencies....
Strange graphs after adding beacon probe
A few weeks ago i added beacon probe to my vcore 3.1 400. after doing all the vibrations calibrations im getting strange readings.. i dont know what to look at atm. im adding my belt tension graph and IS graph for u to see and maybe understans. probably someone can give me some directions?
Y belt dual peak
Hey everyone, I just converted a core XY printer to klipper and use the accelometer of a beacon Rev. H for belt tension and Input Shaper. I've fairly got some experience with building 3d printers and also with klipper, but I can't get rid of this 125Hz peak on the Y axis. The X looks absolutely dope with 14k mzv. I aligned and squared the gantry, made sure that belt tension is equal, zip tied everything that could move and checked every screw. I'd like to at least get below 1.5% vib and over 5k...
V-Core 4 - 300 - Gap between upper and lower
Hello everyone,
trying to tune my belts, but when I tension my belts that the gantry is aligned to the front I always get the gap between upper and lower belt. Does anyone has an idea how to fix it?
And is there any recommendation which power spectral density/tension I should aim for?...
VC4 400 CoreXY - Graph Gut Check
Hi All - Could somebody look at these graphs and let me know if i am on the right track?
Y freq 25hz -30hz - 35hz peak on VC4 IDEX 500
Hello,
I don't know where else to search for removing my frequency :
- rebuild both head
- remove grease from linear rail and use 3-1 oil
- check all zip tie...
VC4 400 IDEX Resonances on T1
Hello!
I've been tuning my belts for about 3 days already.
I tried a multitude of different tension-ratios on x and y, but I just can't get my T1 Y to look any good.

Inputshaper strange things above 150hz
Hello can anybody tell me why I have these graphs above 150hz 🤔
