NOISY Core One
Hello, anyone know why this core one is being so noisy? I've wiped the linear rail and re lubricated with prusa linear rail lube and i used the new belt tensioning feature to tighten my belts good but it is very loud?
RE: NOISY Core One
This doesn't sound wrong to me - it once did but you get used to it...
For an experiment, try adjusting the speed from the front panel. It may shift the "noisy" features slightly in frequency. But for a more systematic way to quiet it down, check "stealth mode".
Input shaper calibration with accelerometer may help (the input shaper finds resonant frequencies and suppresses them in the stepper input). And maybe this particular noise even improves with time (the rattling, not the high-pitched whine). At least I got that impression on my core one.

redo the calibrations in the menus, it helps a bit.

Doesn't seem too healthy to me. I'd work my way around the unit and ensure all screws etc are secure as a starting point.....
RE:
I have that noise too.
This weekend, I finally want to try a few things to see if I can fix it.

(PS: I haven't attached any videos to this post yet, but the sound is exactly the same as on my C1.)
RE: NOISY Core One
The noise seems to occur upon X movements (at specific speeds), which would suggest that it is not tied to one of the motor/belt drive chains, but to the toolhead. The Nextruder covers or fan shroud seem like plausible candidates. I would start by checking that the respective mounting screws are tight, and maybe jamming some flexible/damping material under the covers.
I have seen a detailed exploration earlier -- nor sure whether it was on this forum or some blog? -- where someone had experimented with adding damping materials and redesigning some printed Nextruder parts for a tighter, vibration-free fit. Can't find that anymore though. Does anyone happen to have a link in their bookmarks?
RE: NOISY Core One
Generally this is a sound when movement aligns with the resonating frequencies of some parts - some of them are way louder and prone to resonance.
Rechecking al the CoreXY frame screws, belt adjustments, and other calibrations should help. You could try to grab/push certain parts when it happens to see which one are affected. Another option is to add extra mass to certain areas, which would lower the resonation frequencies.
This sound is nothing in comparison to the specific frequencies my Prusa Mini catches when moving the Z axis - you would literally be scared when you would hear it for the first time

RE: NOISY Core One
My printer recently started getting noisier. Re-lubing the linear rail helped there is still some resonance in the Y axis and probably the only remedy is pulling the linear bearings and relubing the insides. Recently I saw a post where someone replaced the Y-axis smooth rods with linear rails. Not sure if I want to go to that expense (yet).
