Equal tension but low amplitude

I have a question concerning belt tension this graph is pretty good imo (it's not that anymore). So it's matched but low amplitude, but as soon I turn it up my lower belt start fading (overtension). What could explain being so low on amplitude yet being on the verge of overtension. Will try to get back to a graph similar. It's getting mind boggling because before redoing the loom and the wires in the box I printed and I was higher in amplitude

Can you share some pictures of the machine? Belt path, Toolhead,

For the belt path I don't have some on hand I'll post some when I get home

How are those Y belts attached? πŸ‘€ I guess you are still doing the coreXY belts tune, before installing the hybrid belts, as you should! πŸ’ͺ

They aren't on at the moment since I need to get that graph in line

But I got curious anywaysπŸ˜‚ First of all, remove them entirely, one less thing to vibrate
Dank God Precious
Dank God PreciousOPβ€’6mo ago
They securely fixed with masking tape πŸ˜‚ Here we go

Use a zip tie in the front to fix the hot end wires, as I pointed in the perfectly round circle
Dank God Precious
Dank God PreciousOPβ€’6mo ago
I sadly broke it with a zip tie that was too girthy
Cruz

Use the zip tie slot in the middle ebb42 mount, it's kinda hidden, in the bottom, where it meets the aluminum plate (middle arrow)

And clean the beacon cable better along with the 4029 wires Wire management ok the Toolhead is mandatory to eliminate 90-110Hz vibrations

There is only the hotend wires that can't really be tied down with normal attach point I could zip tie the hotend wires to the front fan shroud ? @Cruz my main problem is that my amplitude is low and that I'm on the verge of overtension

Uhm, maybe Can you do a new graph?

I can but it's allover the place I played with it last weekend I kinda have to take it from the start Here is the first one

10th matching but low amplitude

Higher amplitude still matching, moving it bit by bit

Found out my top belt was a teeth too short It's out of wack now πŸ₯² I dont know what to do I can match peak but amplitude low and when I try to go past the 1.2 e6 threshold it suddenly dips and I try to adjust teeth but letting on slip in the front of the upper belt I get back to square one
Cruz
Cruzβ€’6mo ago
this is the current state of the machine? IMO past graphs are irrelevant, as you can't revert the assembly and reproduce them
Dank God Precious
Dank God PreciousOPβ€’6mo ago
@Cruz The current is back to square one as I slipped a.teeth thinking It match my peaks and could escape low amplitude
Cruz
Cruzβ€’6mo ago
why do you think that's low aplitude? looks good to me every machine is different but I don't see major issues with the amplitude
Dank God Precious
Dank God PreciousOPβ€’6mo ago
With that graph I was getting 8000ish MVZ on my X and 2000 on my Y Doesn't the amplitude affect those value? I've seen people getting way higher values than me I may spouting nonsense feel free to correct me πŸ˜‚
Cruz
Cruzβ€’6mo ago
I may be looking at the scale wrongly, but it seems about the same 1e6 My guess is the IS is giving you the low acc due to all the vibrations
Dank God Precious
Dank God PreciousOPβ€’6mo ago
Could I set it to stop the IS before the vibration to get a potential accel when I get rid of those ?

after cleaning the toolhead wiring, and the belt grapsh again, if you are not happy, I advice you to use the resonance analysis tool not really
Dank God Precious
Dank God PreciousOPβ€’6mo ago
It's not clean enough ? For the wires I mean?
Dank God Precious
Dank God PreciousOPβ€’6mo ago
There could be something loose screw wise also ?
Cruz
Cruzβ€’6mo ago
if there is, the resonance tool will tell you hows the belt graph looking now?
Dank God Precious
Dank God PreciousOPβ€’6mo ago
Messed up since I slipped a teeth but won't be able to make new since I'm going on vacation tomorrow πŸ™ƒ
Cruz
Cruzβ€’6mo ago
oh well, are you able to go on vacation and not think about it? 😝
Dank God Precious
Dank God PreciousOPβ€’6mo ago
Most likely

I just saw another user graph for the same size printer as mine I don't think the result of mine is normal

@Cruz I'm back from my vacations on the flight back I was thinking is there a possibility that a motor as gon bad ?
Cruz
Cruzβ€’6mo ago
nah, if a motor was bad the machine wouldn't move preperly
Dank God Precious
Dank God PreciousOPβ€’6mo ago
True so rn im think of undoing and redoing my motors stack Do you think that the heavy idlers would help ?
Cruz
Cruzβ€’6mo ago
the heavy idlers provide a more durable solution, if your idlers are new, I don't see a reason for them to cause this
Dank God Precious
Dank God PreciousOPβ€’6mo ago
Okok hmmmm I'm truly bamboozled by this one So rebuilding them stacks would it be a waste of time ?
Cruz
Cruzβ€’6mo ago
IMO yes, unless something is wrongly assembled how's the belt graph looking so far?
Dank God Precious
Dank God PreciousOPβ€’5mo ago
Been unpacking and doing laundry haven't touch it yet so I don't remember how it last looked But I remember to have tried something and was sent back to square one πŸ™ƒ @Cruz Got my amplitude higher this time i wasnt giving it enough beans on the tension
Cruz
Cruzβ€’5mo ago
Great! Happy to hear
Dank God Precious
Dank God PreciousOPβ€’5mo ago
but still in the tunning phase sometime its too much so back it out a bit, you know that dance
Dank God Precious
Dank God PreciousOPβ€’5mo ago
@Cruz I'm not touching it anymore I'm welding everything in place
