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 🤔
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...
