Bump in Z axis on X and Y graphs
Hey guys! Had a problem with strange vibrations through my prints. From the feel and sound thought about defective X carriage - when you are moving it by hand with belts, you can feel ballbearings “rattling” inside. Change to another one supplied with the kit - same result, changed the carriage to HIWIN Z1 preloaded - much better, but still feel this “rattling”. On the graph there is constant bump on specific Hz on X and Y graph. One of the discord members told it may be the carriage problem. Can this be true or should I investigate further other components (they seemed fine)? What usually the bump on Z suggests?

VC4 500 IDEX IS Y-axis
Just upgraded to the Toro titanium tube to fix my first layer issues and started re-doing the belt tension process. Used the GATS system to set tension with about 4.5kg of tension and got the following input shaper graphs on my y-axis. They look pretty awful, but all the x-axis charts look pretty respectable with MZV recommendations. I am at a loss for what may be causing it. I've traced belt paths, made sure they're centered on the idler stacks and pulleys, made sure the gantry is square (confi...
Possible belt rubbing?
Hello all, wondering if this is a belt rubbing (lower amplitude) or something else?
Possible Mechanical Issue or Binding
I've tightened my belts up a good bit after using some tea bottles as the weight for GATS (2 grams difference between each other), fixed a small gantry misalignment (roughly 2mm), lubed all X and Y carriages, and tightened down my electrical panel.
I'm a bit unsure as to what else may be in play here. Hopefully it's not a squareness issue.
Any thoughts?...
Very low acceleration characteristics on V-Core 3.1 300
For some reason, on V-Core 3.1 I have quite low acceleration characteristics, although the graphs look as adequate as possible without unnecessary noise.
Need help to check my resonance graph. Vcore3.1 500mm.
Hello, can you help me to fix my resonance. Its a vcore 3.1 500mm with v1 toolhead with ebb42 can v1.2, orbiter runout filament and funnsor titanium x gantry.
Thank you in advance for your help!!...
Belt tension Shaketune
Ran shaketune for belt comparison, this is my belt tension and resonances. How am I looking?
Y Spike on X-axis graph at 63hz
I cannot seem to make this spike go away. I squared up the frame. I tension the belts to about 16lbf. I made sure pulleys weren't binding. I am at a loss. I hope I'm not just having a brain fart moment. 💩
It's a V-Core 4 400 IDEX....
I can't work out what these strange vibrations are
I have a VC3 400 and I can't work out what these strange vibrations are at the end of my graph. Also do they matter in this case?
Uneven Belt Graphs VC4 500
Hi! Whats the take on those belt graphs? Cant get them even for my life, so I think there is some deeper issue here. Shaper graphs look okay-ish. Thank you!
What Do You Think About My Graphs?
Just wondering if these results look good to you guys if there is some obvious room for improvement.
Belt tension VCORE4 IDEX 500mm
Hey guys, any advice on what to do? is this graph acceptable? Also how do I make sure my belts are under correct tension with no tensometer? I tried to use the frequency measuring tool on my phone, but the data it gives me is so random, basically impossible to read. Any advice?
V-core 500 Hybrid y resonances
good morning.
I've been trying to solve a problem with the y-axis resonance graphs for a few days now. The graphs in X are perfect, but I'm still having problems in y. I tried to check that there were no vibrations on the gantry and that the belts were sliding correctly. The last correction I made was to tighten the frame nuts to 13N/m. I noticed that it twists and dances a lot during printing. I always thought it was normal given the size of the printer (v core 500 hybrid) but unfortunately even tightening didn't solve much. I'm attaching the graphs....
