Can't work out what this peak is
I have this peak when testing the belts. Nothing along the belt path is binding I just can't work out what it could be. Running ebb42. Switched to a completely different toolhead assembly and it's still present.
Belt tension graph is not behaving
I've tried everything, this is the best I can get..
Any help is appreciated...
what should I be aiming for for belt tension?
I've gotten the belts relative close in tension but what frequency should I be aiming for? Do the belts need to be tighter or looser?
Help for a newbs. How to adjust the belt tension ?
Hi,
i generate the graphic for the belt tension, how i can read the graphic and how i adjust the tension on the v-core 3.1 ?
Sorry for the question but i 'm a noob
thanks...
A resonance study - test series
...was having an alternate conversation and a few points were brought, correcting my (misguided?) insight that was based on what i'd been seeing in my setup.
So off i went to run a bunch of tests. Using my scale pull test to set a calibration point on my meter I set my belt tensions to 1 lbs, 2 lbs, 5lbs, and 10 lbs. running belt tension tests ate each tension. 'THE' tuning video says you should have two peaks per belt tension. BUT... I'm now running into manufacture specs vs end user prescriptions that do not agree. At 1-2 lbs, I kind of get a sloppy graph with a second peak for each belt. but I can watch the belts vibrate badly and slap the frame and even the gantry on this VC500 at those low tensions. At 5lbs (which is still well below the manfuactures suggested tension) I get one sharp peak, and no secondary peak as the video suggests.
At 5+lbs, (apparently I was running at around 6.5 lbs) is my highest acceleration suggestions when running input shaper.

AWD enclosed VC 3.1 500 y belt tension issue
ok so im doing the belt tension right now and my x axis is looking very good, however my y is not. im looking for some input on what to try next to better suit my y axis. where are the graphs. the rear motor are FMMM tensionless back plate the only tensioners are built into the AWD motor mounts at the front.
High peak at around 130Hz in belt tension with FMMM
Hi,
I've been searching for a while now and checked almost every part of the printer. I checked every part on the EVA and every idler bearing. The tolerances are fine, nothing is overtightened. Nothing is rattling except for the SSR in the Back on a DIN-Rail a bit.
At this point I'm really clueless what is causing this high peak.
I recently switched to the FMMM Mod and have Metal mounts for the front idlers too....
Just re-tensioned my belts (VCore 400)
Hi everyone.
Just wondering about people's thoughts on the below graph. seems the belts are pretty similar now, but a bit of a hiccup at 125Hz. Should I be investigating further?...
V-Core 3.1 Enclosure 2.0 500mm Belt Tension & Resonance Help
I'm trying to make out what these graphs mean and how to correct them.
I rebuilt my toolhead out of PolyMax PC + heat inserts the other day along with made a revision to my EBB42 mount (in-front of LGX Lite).
I'm planning on tearing down the printer to replace the PETG core components w/ PolyMax PC components over the next few days.
I've been printing mostly high temp ASA, PA6-CF, PC functional prototypes with pretty good luck but want to make sure that I don't repeat something that I shouldn't when rebuilding....
What should I do from here?
vcore3.1 400
I'm not sure I know what I'm doing, so I'm asking you guys for some input...
Weird ~117Hz X Resonance and Belt Tension Graph
I have a Vcore 3.1 500mm that is sitting on the floor. I am getting an odd peak in the X-direction at like 117Hz any ideas?
Additionally my belt tension graph looks a bit odd....I think? Still new to reading these. The peaks seem to line up, but there are 3 of them, is this normal?
Thanks for the help!...
Good/Bad? RR vCore3.0 500
First, I watched the video. I'm not sure how much I understood from it, but think these are ok, but would like someone with actual experience to give their opinion. The peaks match in frequency and "power" pretty well I think. The extra 42Hz "step" going up on the X probably isn't good, I can't remember if he mentioned such an artifact. The stair step down a couple of steps on the Y, probably not good either.
I'll watch the mentioned video again, but not sure I'll pick up on what I need to do. Thank in advance for any critique or advice....
v-minion Y issue
I think X looks quiet good, but Y is a bit strange to me. What could be the reason? I tried to tight all screws, used belt tension meter to adjust belt tension but graphs are still more or less the same...
V-Minion first Run
Hello. this is my first printer with ratos and klipper. setup with orbiter and rapido and eva 3.0 and adxl on toolboard ebb42 and own adxl on the aluminum bed. what do these curves tell you? are these bad? heard something improved or belt adjusted? what do I have to do in the config or where do I have to use this value so that the printer knows the limits? greet andi
What to improve? (vCore3.1 300mm)
Hi,
I just finished building and setting up my vCore3 and ran input shaper, though I am not entirely sure what to look for and how to improve.
Any help would be very appreciated!...
Idk what im looking for here.
looks like Y is pretty good but X still a bit dodgy. idk what to really look for with my belt tension graph, but it looks like X might just have something loose ?????
Need Help improving graphs (EVA3.0 extruder VZBot330 Motion system)
Hey does anyone have recommendations on what I could improve (especially on the Y-Axis), I don't completely understand those graphs yet, also I'm getting some pretty brutal rattling noises from my printhead.
