VC4-300 IDEX something off, hope it is the belt tensions
Hey there ,
I tried to fix my belts with the 9 mm belt tension meter. They are now all almost the same tension.
Nevertheless there seems something off with the system....
Solution:
But run the outer 4800 for now.
VCore 3.1 500 belt tensions seem eratic
I can't seem to get my belt tensions to align beyond around 35hz. After that they seem to go all over the place and the lower belt has that huge spike later on.
VC4 Idex Belts
Hello,
I tried to fasten my belts but no matter what I try I always get a bad result.
Best I archived until now is attached.

Custom VC3 input shaping interpretation
Hi All! Im getting close to finishing my machine and started looking at the input shaping graphs. However its my first full custom printer and my first time looking at input shaper graphs. Can some of the smart eagles out there tell me what I should be looking at?
The machine is a 400x400mm with MGN15 rails for Y and 2 carbon rods with Iglidur bushings for X. My main idea was to get the X+Y weight as close to the X weight to get higher overall accelerations while keeping quality high....
vc4 500: What am I looking at?
If I'm reading this graph correctly the lower belt should be tensioned in order to achieve the same tension as the upper belt. But doing so results in a skewed gantry. Could something else be at play or are the differences in peak heights normal?
vc3.1 400 impossible to align both peaks
I'm trying to maximise the quality of my v-core but i can't find a solution to make the yellow line as high and synced with the blue one.
Need advices please...
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.
