Enclosed VC3.1 300mm Belt Tensioning
I've been trying to make sense of the belt tension and resonance graphs for an enclosed VC3.1 300mm I just made. It has the FMMM, Motor Decouple-Damper, an EBB42 and it's sitting on the floor (on floor tiles, so maybe that could contribute to my problems, though it does not have any noticeable rocking). I've watched the youtube video that is recommended everywhere for
how to read and analyze input shaper graphs..., and took a look at a fair amount of posts/messages here, but in trying to follo...
what is this extra peak....
belts arent binding anymore. got good belt resonance graph. but still have this blue peak on my Y resonance. while X looks pretty good.
XY matches, but....not tight enough? maybe?
is it possible to tell from a resonance graph if your belts are tight enough? here's my graph. you'll see that X and Y are pretty much equal. But my prints lean rather heavily. As you go up in Z, it seems to shift in both X and Y directions. I wondered if maybe my belts simply aren't tight enough?
Bad input shaper Vcore 500
Anyone have an idea? I've been thinking about this for a few days now... Neither Zv nor Mzv helps on the Y axis. The X axis is probably OK. Speeds are 100 fastest, acceleration 3500. Vcore 500
pressure advance values not respected in printer.cfg
The printer isn't using the set .3 pressure_advance setting

Need help interpreting graphs for 400mm V-Core 3.1
This is my first core-xy printer and even after watching the frequently recommended YT on these graphs, I am not sure how to interpret them. From that video, I get the feeling these graphs would suggest some binding on my x-axis. But I cannot feel that binding myself when i turn the motors off. Is there something else i should look at?
First steps with my resonance
Hi everyone. I am trying to tune my v-core 400 and also the accel. could you kindly guide me in a direction? These are the two input shaper graphs. From my understanding there is a huge gap between x and y because the peak of X is at around 62Hz and the one of Y at 42Hz. Is this a belt tension issue?
Trying to tune Vcore 400mm
I attached the ADXL345 accelerometer to Vcore 400mm and ran the macros in RatOS for belt tension and input shaping.
I gather working on belt tension should be done first, but my graph looks nothing like others, so what does it mean? Too tight, not tight enough?...
Is this okey?
Vcore 3.0 300x300x400 with openfront, eva 3,ballbearring idlers, 4028fan, ebb36(little bit tilted, need other standoff)
I´m thinking, x belt to tight,y to lose or am I incorrect?...
I dont rly understand this
On my belt tensioning the second peak is completly missing,the belts are exactly the same tention for the first peak.x and y is is kinda weird since x is lower than it should be imo.I'll Appreciate any help
Input Shaper is on, but still getting ghosting
V-core 3.1 500. I have done SHAPER_CALIBRATE and input shaper is in the printer cfg, but still getting ghosting. I thought my graphs were looking good, but I guess not.
What can I do to prevent ghosting and ringing like I am getting on this temp tower?...

Just a question
are my shaper graphs labled wrong on there axis? I just got a new usb adxl, trying to figure out how to set it up.
will more tuning help?
Hiya,
I’ve spent a couple of hours trying to figure out the dark magic of belt tensioning on my enclosed vc3.1 300z
I started with trying to set a rough belt tension using spectroid based on the advised 85 to 110 Hz frequency for a vc300.

help needed to fix resonance
Hello all, someone can help me figure out if this two graphs are correct or if they show that some action is required? I saw all the video on youtube from the commissioning guide but honestly it wasn't that easy to undestand 😇
