Inputshaper strange things above 150hz
Hello can anybody tell me why I have these graphs above 150hz 🤔
Is this good or does something need fixed? Hybid vc4 500
I've tightened bolts everything appears tight though something does sound loose when it hits certain frequencies but darned if I know what to look for now.
VC4 300 IDEX - How to interpreting belt tension and input shaping?
Recently I finished my VC4 300 IDEX built and now trying to tune it.
However, I really don't know how to interpretate the graphs......
First time resonance test
Hello , I've just ran a first resonance test on a 400x400x900 Vcore3.1. I'm really new to this - so sorry if this is obvious - but - are there any problems with these graphs?
Need help with XY axis
I have vcore 4 hybryd, its my second ratrig, and VCore 3.1.
Problem is with VC4.
I have everything set in printer.cfg
belt tension was set with sonic tension-meter. Its giving me answers in Newtons but I can tension every belt with the same force. I'v done that by setting extruder to the back and mesure the lenght of the belt from center of the pulleys. I use sonic -meter instruction for that....

Unsure How to Fix Based on Resonance Plots
I just finished tensioning all the belts (around 8 or 9 lbs based on frequency) and tension plots are absolutely horrid. I don't even know where to begin to start with this. I checked all the pulley gears and they look to be centered with the belts. I do hear vibrations, with the loudest being the base plate (plate covering the bottom of the machine). When I put my hand on there it damps out most of the vibration noise. But it still sounds like there is slight rattling noise. On my T0 toolhead I have the orbiter runout sensor installed and am wondering if that is contributing to the rattling noise. If i listen closely, it almost sounds like the balls in the linear rails that are rattling. Is it also possible some of the t-nuts for the linear rails (or any other t-nut I guess) didnt actually rotate properly and ended up not gripping the frame? I don't know how I would even tell since I can't look under the rail into the channel of the aluminum extrusion. The screws all seem tight though, nothing loose.
It looks like the Y belt plots are much much worse. The X plots look at least acceptable. The whole structure seems to shake between 50-70Hz (rough estimate) during the Y belt process. I have the machine sitting on a quartz countertop so I assume thats pretty decently flat.
I've attached my belt tensioning and shaper results for reference. All of these steps were performed with both CoreXY and hybrid belts attached, since it looks like IDEX does not work without the hybrid belts....
First Time Doing Belt Tuning... Looking For Guidance
I think I need to tighten the lower belt. Is this correct?
vc4-400 idex - interpreting shaper graph - ghosting on y-Axis - VFA on x-Axis
Hello, I need help troubleshooting my new vCore4 Idex.
What have I already tested?
- I have replaced all flange bearings with the heavy duty idlers
- checked that all screws are firmly in place...
Belt tesnion V4 Hype / Idex
I made the Upgrade to the Hype / Idex and have some troubble withe the belts maybe someone can help 🙂 ?
Interpreting belt tension graphs
I just upgraded my Vcore 3 to 3.1 and Ratos 2.1 RC3
tensioned the belts to a kina equal tension just by sound and now ran the frequency measure belt tension macro
The first Result I interpreted as lower belt being too loose, increased by half a turn and ran the second test. It barely changed and from the tone the belt makes when manually "stroking" it the lower already sounds higher (so more tension)...
Better results with Mirror/Copy than Single? 500 IDEX
So, I'm getting mixed results in Single mode vs Mirror/Copy.
500 Idex.
I get consistent MZV recommendation on Mirror/Copy but not on Single.

A lot of noise and spikes on Y
Biqu belter at 6.8mm, graph looks terrible and those spikes at 125hz… has anyone ever experienced this?
Any suggestions?...
IS Numbers
I came up with a theory today, after making a few observations on Klipper's mzv accel numbers returned from input shaping freqs. I know much is not explained here, but its simpler than people think.
The mzv accel number is not some magic algorhythm that comes from complex calculation. Its a nearly linear scale plot, based on the frequency that your x or y axis center resonance peaks at.
I took 11 mzv freq's and accels from this Discord, and plotted them on an Excel chart, just to verify my hypothesis. As you can see, Klipper applies the recommended accel in a nearly linear manner....
Belt Tension check V-Core 4 400
Hi, after some tuning I came down to these resonance graphs. I tuned belt tension to just below 75Hz which I guess is somewhere just below the recommended upper limit? How does it look? Room for improvement?
