vc4 300 hybrid input shaper
Hi everyone, I got my belts tensioned and installed the hybrid belts.
These are the graphs that I'm getting.
They look good but I think the accelerations are a bit low.
Do you have any idea how I can push this further?
Also, tight now I have MZV on both, how would changing it to only ZV affect print quality? Cause it giving me around a third more....
belt tension
Second peak missing hight. Tried everything and its always like this. Hybrid belts on is there change that they cause this?
belts issue
Hello I have the problem with my belts. (V4 500) the first picture was before I was trying to get a better result. I only tightened the belts not more but then I got the second pic.
Tried it 15 times loosen and tightened the screws. Any tips or ideas ?...

VC4 500
Hello, I'm currently adjusting my VC4 500 Hybrid. So far everything has gone well and I have installed the hybrid y belts, now I have arrived at the input shaper. I just can't do much with the measurement, i.e. I have no idea what it is telling me. Not even after hours of reading here in the discord. Can anyone tell me why i have a 2nd spike on y?
VC4 300 Hybrid belt tension
Hi, I'd appreciate your help and input.
I started tuning the printer and noticed I had the upper belt motor pully upside down.
I flipped it to the correct orientation but now I cant seem to be able to match the belts.
The lower belts is at the end of the tensioner so i cant pull it tighter and I'm not sure if the graph is OK or not.

V-Core 3.1 500 Unenclosed
Greetings, I hope you are all having a great day. May someone please help me understand the frequency response and shapers/belt tension resonances please? (I'm colourblind and have a hard time identifying which line represents which value). Thank you in advance ❤️
v-core 4 500 hybrid - belts tension and motors help
Hello, I have a vcore 4 500 hybrid enclosed. I'm experiencing multiple issues, but I'll post the bed mesh ones in the other dedicated channel. My goal is to print large ASA parts but either due to warping or for ringing, I can't achieve good results.
These are the graphs I obtain without the hybrid belts. The hybrid motors are mounted and hooked btw.
- Can someone help analyse what's wrong here and how to fix it? I've already disassembled and reassembled all motor plates, bearings, spacers and belts: they seem aligned.
- All bearings should move freely: but does that mean that they have to spin a bit after making them spin with the finger fast ? Like a skateboard wheel ? During assembly I noticed some of them were spinning very freely while others just normally, with not much inertia after the spin....
Not having any luck fixing the belt tension.
I've redone the belts and as far as I can tell the gantry is true. What else should I look for?
VC400 Hybrid belts kicking my butt and taking my lunch money
Tuning my Hybrid belts is becoming quite the ordeal. Stock coreXY mzv Y acceleration is about 3700, adding y belts only takes it up to 4200, but the response is terrible. If I do tune the y belts to make an acceptable graph, the acceleration will still sit at around 4000, but the belts are just tightened with finger strength, nothing more. I tried tuning with the pinned macro isolating the y belts, but I can't tighten or loosen the belts to get the response to be anywhere close to matching.
first 3 added pics are during core xy. Last few pics are during hybrid calibration...
Solution:
Solved it. The hybrid belts needed to be much tighter than I had initially. I bottomed out one of my tensioners.
Please comment VC4-300 CoreXY and Hybrid
These were my charts for CoreXY configuration after tuning (Ok, but not great; I just was not able to get the peak at 100Hz away)
V-Core 3.0 500 Belt Tension
I'm wondering what I adjust here, is this just a dark art or should I be loosening/tightning one or both belts until the vertical peaks line up? 🙂
VCore4 400 CoreXY Graphs
Just finished building my VCore4 400 CoreXY. Wanted to make sure my graphs were decent before I went to add the hybrid kit.

Currently trying to get my belts even
Solution:
How does this look, dropped both to around 92hz
VC4 500mm - Can't figure out toolhead vibrations
So, I finally got some good graphs but I've always had this same noise on all my graphs. I can't figure out where it's coming from. Here is my latest graph and pictures of my toolhead. I rebuilt and retightened everything down on my toolhead. Rerouted my wiring, tried different orientations. I just don't know what to do at this point so any help greatly appreciated.
The noise is the same in every graph at the 115-135 range. Has that exact same shape. Just need some guidance on what to look for or if I should just move on. I get it, look for loose stuff on the toolhead but I've literally checked everything. I've wasted an incredible amount of time trying to fix it and have projects that I need to get printed and done. Thank you.
Also, I just realized that I can run the tension graph even without changing anything and it will produce different results. Maybe I should just align my gantry up front and call it a day....
Vcore4 500 First Belt tension
Just ran the first Belt Tension Test and anted to verify that this is looking ok.
Curves are pretty much the same except for the 110-130 Hz range.
Thanks....
Vcore4 Hybrid belt tension
Hello, would someone comment if this looks good for a hybrid V4 400? I don't know what to make of it. Thank you
weird belt tension graph
Hi, I have 2 opposite peaks, and I don't know what to do about it. at first I had the graph labeled 000 then I fiddle with it, make it worse, tried to get back to the original and now I have the second graph, prefixed with now
my x gantry was slighly skewed, which I solved before doingt those measurment with the belt tensionner.
also I applied too much torque (9.8 Nm instead of 0.98 Nm) on the Y rails, stripped all the screw and they cannot be removed (it was my first time using a torque wrench, I tough the screw sripping was the wrench telling me 'that's enought')...
Could use some guidance on the psd graphs. VC4 500
Having trouble with my resonance and tension in the belts and I’m not sure what to look for and what to adjust. I get that clicking noise in my left stepper if I tighten too much. I see some people with max psd in the 4-5 range but mine seem to start clicking if I do more than 3. Will have to double check the exact value, I just hate hearing that sound so avoid tightening too much.
I can’t seem to get the blue line to match up with orange no matter if I tighten or loosen either side. They just vary in maximums and difference but orange is always higher than blue. Maybe I need to focus on getting the first spike before that.
Lastly is the jump from 115 to 135. I know it’s a tool head issue but can’t seem to figure out what exactly it is. I also have that weird rise towards the end of the graph. ...
