VC4 400 Hybrid Input Shaper Sanity Check
These feel like reasonable vibration and accel values to me but would love a second opinion. What would you set max accel to with these numbers? 8k?
Thanks!...
VC4 400 Hybrid
Please evaluate and interpret the charts, I've been struggling all day and I still have one peak.
"Oh, my V-Core 3.1 is working almost perfectly. I'll make it even better" then this
I'm a moron.
I had my V-Core in a great spot, but I started getting some weird resonances. At the end of my troubleshooting I replaced the rails/carriages, which got rid of the resonance noise, and also put in a light weight gantry. But while doing all of the prior troubleshooting, I must have misaligned something related to the lower belt and I believe from the belt tension graph it must be binding somewhere? Would the the lack of higher frequency resonance suggest an issue with the back run of the belt?
All micro shims are installed and accounted for as well....
VCore 3.0 300 Belt and Resonance graphs
Picked this up used pretty cheap, done some adjusting and these are where I am at now. I used Klippain Shaketune to generate them. I'm planning to reprint and upgrade the printer to 3.1 sometime in the future so I'm not after perfect results, but curious to know if there's any obvious things I could check that would improve these without taking things apart right now?
Peak 68hz on x and y
Hey guys,
does anyone have an idea what could cause this peak @68hz?? It is on x and y, so i think it is related to a belt or the printhead....
V-Core 4 400 COREXY - Y-graph
Hello
While my X-graph and belt tension graphs look good, the Y-graph looks somehow terrible and I don't know where to start. My assumption is a faulty idler pulley on the right side. Any ideas?...
VC4 400Hybrid What am I looking at here?
Following the guide I get to belt tension test. Y motors unplugged and belts disconnected. Not gunna lie I just folded the belt in half and cut it then pulled each as tight as I could and locked it all down with tensioners full loose, then tightened until it felt right, fined tuned to align gantry and happen to have same length hanging out so?. What's this mean tho? Do I need to pull 1 more tooth through on the upper? Did I nail it? Both to loose? to tight? I watched a very in-depth youtube vide...
VC3.1 300 - Chaos on the Y Axis
Hi there,
Have been putting my VC3.1 back together after moving house but I am seeing chaos on the Y-Axis input shaper graphs.
It's running RatOS 2.1, the stock motors with 4 Beam Ruland Decouplers, BRS Belt Tensioning M2 in PC-CF, Toro-Tube & Toro-Rail, Honeybadger medium-preload Y-Rails, and new bearings on all points.
...
No matter what I do I can not get rid of the third hump
I have never had this issue before
Everything I have read suggests this is a belt path issue.
The belts are all runing more or less in the centre of the bearing stacks
The belts are running in the centre of the motor pulleys
The belts are not rubbing on anything...
VC4 500 Hybrid - 2 close peaks on Y
I just got my hybrid belts on after finally getting decent graphs from corexy. I haven't seen a graph like this come up in here before so I'm not really sure where I need to start my next steps of troubleshooting.
I was able to find a few leads on the double peaks from the shaketune github. One was that they can come from a wobbly table but I'm pretty confident it's not a factor. The top is a steel plate 28mm thick and doesn't like to move.
Another suggestion is frame squaring. I think the frame is about as square as I'll get at this point. Beacon gantry twist macro has ranged from -43 to -51 um on recent runs and bed mesh range was .288 on my last run. ...
VC4 300 frequency response what can i do better?
Hi i test the half day but the result is most of the time equally
Maybe are the Belt length are the problem?...

Y Achse Shaper sehr seltsam :/
V4 300 leider noch kein Hybrid :need: kommt aber hoffentlich bald! 🙂
jemand der mir evtl. helfen kann wo dran es liegt? Das die Y Achse so schlechte werte hat :/

VCore 4 400 belt issue
Nice and even but no second bump and no idea where to start to try and fix that so any help would be much appreciated. The graphs are in order of newest to oldest
Vcore 4 400
I'm tuning the core XY belts on my Vcore 400. The first peak amplitude is lower than other graphs I've seen. I did correct the gear heights and it helped a little. Is this graph acceptable or is there some other cause of low amplitude at 50 ish Hz?
Thanks for any advice....
Kinda' stunned... do these still look good to you?
2.1 up and running.... a few kinks but I'd printed my old .cfg so was easy to fix the oddball stuff....
first res under 2.1 belts look REALLY good to me.... vibe seems about the same. (between version, so no ill effects on ops... woohoo)
The ability to just set a Hz and let the machine vibe while you dance around fingering parts to quell noises is FANTASTIC.
....anyway.... thoughts? flames? suggestions? yes.... I prefer my belts a tad on the tighter side (VC500 3.1 with RoS 2.1)...
Solution:
the input request in the loop (to continue the loop or not) is the 'pulse' I'm hearing as you describe. And yes, I do not see it effecting the graph/responses from the printer in the graph. You confirmed my query.... it's not an issue., was simply an observation on my part. tnx
vcore 4 500 belt issues....at a loss
I've tuned and adjusted this like 50 time over the last week and I'm struggle on how to get the graph to look better. I have an extra peak in the lower belt. Are the belts supposed to slap against the frame at certain frequencies? Or do I need to tighten more?
Belt Tension Alignment
Having trouble getting my second peak to align in the belt tension graphs on my V Core 3.1 400, both belts tensioned to 70Hz and the first peak lines up perfectly, but the second won't. Doesn't seem like the belts are rubbing anywhere that I can tell, and the gantry is aligned in the front according to the assembly manual
Unenclosed vcore3.1 500mm issues
I've tightened every single bolt and grub screw, checked square as best I can but having trouble nailing down where the vibrations are coming from. Any ideas on what to check?
