Help with x resonances
My y graph looks near perfect, but the x is having problems. Does anyone know what I should do?
Over dampening?
Was trying to figure if the frequency graphs look good or not and what shaper to select. Based on what I have read: if the Y peak is bigger than X, it means that it's over over dampening. Is it generally always true or does it depend on 3d printer design?
Advice with the graph Vc3.1 300
Is someone able to guide me a bit with this graph? I watched couple of yt videos and what I got is that is "overdampening", what does that mean? And any advice of how to sort it or do you see other problems? Thanks!!
new minion
so, i got this minion partially setup, everything is tight on y axis, no bed yet, no wires either but the Y resonance graph is a mess. this is the simplest belts path possible . what am i missing here ?
Hint for having wierd resonance ....
Recently i noticed a very odd resonance on my X and i could find it and i went through replacing all bearing stacks and the X rails but still had this odd resonance (see picture)
When i was listning during a resonance measurement i notice an odd sound coming from the Eva part cooling duct and decided to take that off for inspection ....... Well noticed the wall was not supported anymore and broke where the circle is.
Just as hint / tip for all here if you run into similar issue and cant piont what it is, it might be worth to check that part and save yourself searching for hours....
Belt tension graph weirdness
After fixing skew by re-tensioning the belts, I get this graph. Does anyone know what's up with the big peak to the right on the blue graph? @fractal_0
Are my 500 belts even according to the graph?
Are my 500 belts even according to the graph? I read somewhere I should aim for around 72hrz
V core 3.1 500
I just build and test my V500.
I don't know whether it is good or not.
Y axis recoommanded shaper and accel seems to low to me. (mzv 3400) is it normal for V500?...
VC300 belt tension?
Just ran for first time, didn’t realise was so out..
Is higher or lower better? I take it the higher up the graph the slacker the belt?
What’s good numbers?...
vc300 should I try to improve this?
belts are not evenly tensioned yet, this is after modding motor cages (decoupled now)and fixing some bad bearings
V-Core 500
My shapes look like this, I still have to cut my belts. Are my belts thight enough to be cut?
Resonance help for v-core 3 500
I just completed the update of my v-Core 3 500 to 3.1. I am really struggling to get it dialed back in and went to try out the new belt tension macro and after watching the video's and reading the old messages I believe my issues are the resonances. After seeing my first graphs and observations during the test I could hear vibrations coming from umbilical attached to the EVA. I have reprinted and reinstalled slipped heat inserts making that attachment stiffer. I also have the mesh table and I added corner bracing to that and used a clamp to anchor it the x direction. I have checked various bolts etc but not finding anything.
I would like to get some advice on where to start or if maybe someone can see something specific to look at since it's such a pain to dismantle ....
