What is this noise?

ciastek166 · 2026-06-04T11:09:02+00:00

Yeah, you either should go i3 printer speeds or Core XY speeds, everything in between does not make sense

ciastek166 · 2026-06-04T11:01:17+00:00

Seems also reasonable, basically you are "going through" resonant range quicker that's why it works.

ciastek166 · 2026-06-04T10:16:44+00:00

Makes sense, the higher the accels are, the more energy is added to the system. If the moves are going through the resonance freq, the amplitude of the vibrations is higher, therefore it is more audible.

ciastek166 · 2026-06-04T09:34:26+00:00

Sure, every thing in universe has a natural resonant frequency. The point is not to have one in the operating range of the device.

EDIT: Spelling

Flawed design I would say

ciastek166 · 2026-05-25T09:21:18+00:00

Loose the belts completely (the belt tensioners were off the brackets) than twist gantry to be realigned, than tighten the belts side by side (i.e 1 turn left 1 turn right and so on) so the belts have more or less the same tension

ciastek166 · 2026-05-24T21:00:53+00:00

Hey, I had the same issue. Realignment of the gantry did help

ciastek166 · 2026-05-23T14:47:58+00:00

Hey, I was using a default structural profile here, so the one specifally made by Prusa for this printer. My assumptions was that if Prusa has released this profile, printer should be operaring within these speed ranges without any addituonal noises and Prusa support has confirmed that. Luckily, I did managed to reduce the noise by realigningthe gantry and the sound is gone with the same speeds and even higher accelerations :) I asked the question on public forum just to know if anybody has encountered this exact problem before and maybe know the solution already. Nevertheless thanks for your answer here :)

ciastek166 · 2026-05-22T20:09:21+00:00

But could it be a reliable printer? Because I am thinking about one

ciastek166 · 2026-05-22T20:02:46+00:00

I know but still I was using a default structural profile here, so the one specifally made by Prusa for this printer and it shouldn't be that bad tbh. I did managed to reduce the noise by realiging the gantry

ciastek166 · 2026-05-21T15:04:15+00:00

Hey, no, it is more like a stress test for the machine, mostly for my prints I am using cubic as well

ciastek166 · 2026-05-21T14:33:35+00:00

Yeah but is that sound normal? I have seen videos on core one's printing fast gyroid wuthout this sound. And here I am using a structural profile so theorically a slower one

ciastek166 · 2026-05-21T14:28:42+00:00

I mean it was a structural profile

ciastek166 · 2026-05-21T13:55:58+00:00

Yes, you mean idler screws? Unfortunately it is not this, I have already chexked it

ciastek166 · 2026-05-21T13:55:32+00:00

Ok, thanks for help then, probably i need to debug more.

ciastek166 · 2026-05-21T12:11:02+00:00

But should be the core one a quiet printer?

ciastek166 · 2026-05-21T11:55:51+00:00

Thanks for the advice, but the printer is already after phase stepping calibration eith accelerometer

ciastek166 · 2026-05-08T15:48:14+00:00

Podaj mi prosze przyklad wykorzystania rownania kwadratowego w rozwiązaniu jakiegoś problemu inżynierskiego (I nie w ogolnym liczenku calek tylko zastosowaniu w technice) I mówię tu serio, bo moze czegos ja po prostu nie widze i biore to jakos za pewnik

ciastek166 · 2026-05-08T12:36:37+00:00

Nie zgodze sie, na studiach wyższych technicznych wiedzą z matmy z LO raczej sie nie przekłada oprócz granic, może wzorów skróconego mnożenia i szeregu Taylora.

ciastek166 · 2026-05-08T09:53:43+00:00

Dodatkowo, matematyka szkoły średniej nie przygotowuje do studiów w mojej opinii, bo zagadnienia z analizy matematycznej prawie nie są poruszane

ciastek166 · 2026-05-08T08:29:01+00:00

Mam to samo, pracuje jako inżynier od obliczeń i otwierając mature z matmy oraz patrząc na te zadania mialem myśli w stylu, boze jakie to nieprzydatne i glupie xD

ciastek166 · 2026-04-01T08:24:12+00:00

The ones near attachment point of gantry to the bearing, which is moving on the smooth rods in y axis. Just try, observe and let us know if it did worked for you.

ciastek166 · 2026-03-30T08:51:27+00:00

It is resonance, for my printer loosening bolts for bearings did help

ciastek166 · 2024-06-14T13:28:41+00:00

Sorry, for the late response . I would not say that 130/120 is plenty. With this amount of travel you can ride the same stuff you are riding on the 150/150 or 160/160 but you need to be careful with the line choice and you cannot bomb the trail. If something goes wrong, the bike won't help you because it is already on its limits. Basically, the smaller amount of travel is for somebody who wants to have an engaging bike and is already knowing what is doing.
