V-core 500 Hybrid y resonances
good morning.
I've been trying to solve a problem with the y-axis resonance graphs for a few days now. The graphs in X are perfect, but I'm still having problems in y. I tried to check that there were no vibrations on the gantry and that the belts were sliding correctly. The last correction I made was to tighten the frame nuts to 13N/m. I noticed that it twists and dances a lot during printing. I always thought it was normal given the size of the printer (v core 500 hybrid) but unfortunately even tightening didn't solve much. I'm attaching the graphs....
Vcore4 IDEX 400 t1_y Resonance Graph Wildly Different
Does anyone have any suggestions on where to look for this. My t1 y resonance graph shows a large offset between the x and y lines. I have no idea what to change, as all my other graphs the x and y mostly line up vertically. I did check the gantry moves to the back where both sides touch the motor cages simultaneously. No matter how i tension the belts, the t1-y always has offset x and y curves.
Any idea what could be the problem? I checked nothing is loose and the belts are roughly centered on the pulley (the belt seems to be manufactured not exactly straight so it does ride up and down a tiny bit touching the 20 tooth pulley lips depending on where the print head is))

VC500 3.1 Long Standing Issues
Hello, my printer hasn't worked in nearly 6 months and I don't know how to fix it.
It is a VCore 500 3.1-ish. The following modifications have been made:
- Swapped to VC4 motor mounts.
- Using different joiners and a top mounted rail (but the problem persisted with the old joiners and Y-rail location)...
impossible to adjust
Please help me
On a vcore 3.1 with RATOS 2.1, I can't get any ripples. Below are my graphs.
Can you tell me what's wrong?
Thanks....
IS Noob needs help with Y axis shaper :/
Hey I am fairly new to IS and my Y axis looks shit, I dont knw what could be causing it, could someone with a little IS experience maybe have a look?
Swapped EVA -> RatRig toolhead and massive resonance spike
I swapped my eva toolhead to a ratrig toolhead recently and changed from an lgx lite to an orbiter v2.
During the recalibration process i started noticing that a few of the frequencies had really bad resonance at double the oscillating frequency.
Most of the frequencies were fine, but oscilating at 90hz for example, I get a really bad resonance at 180hz....
IDEX 500mm Resonance Help
My x looks okay, but my y not so much. Not sure why I am getting the two smaller peaks.
Need help with resonance
x graph i believe looks alright but the y graph is vibrating much more than x and also speeds are super slow i assume. I am new to this type of stuff so maybe someone could help me fix the issue or tell me what might be the issue of this happening?
also tried this after these graphs but the code just wont work then and printer is disconnecting. any tips?🥲

Aweful Graphs .... regardless what I'm trying :-(
Dear all, I can't get my VC4 400 IDEX running. I disassambled the whole gantry 3 times, all mgn rails are running absolutely smooth, Y is moving like a charm, .... and in the end, when I put everything togehter ....🤮 checked all screws over and over again, tried different belt tensions .... always more/less the same result. My VC3.1 has a perfect grapgh, but this IDEX drives me crazy. Any help/idea would be so helpful - thank you so much!
Y-Axis Scatter after main hump
Getting a grouping of misaligned humps after the main hump on Y-axis.
X-axis looks good I think.
Any help appreciated!
I've got the Y-axis running better and doesn't seem to be binding, all bolts were checked to be tight. All wires are cable tied and supported....
V-Core 4 500 IDEX resonance
After doing a full resonance test I am left with these graphs. Are they they as expected?
Tensions...
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....
