I don’t think the bushings are defective, as it is a problem that many users have. Something misaligned or something loose I think is an option. I haven’t found a way to fix it yet.
Is the same sound. If you have time can you try to increase speed of first layer and check again?
Does anyone know which screws Kochlewsky was talking about?
Removing the front casing, below in the nozzle area you can see 2 screws holding the bushing. I also loosened them but the noise persists. I tested removing the XZ belt and moving the head by hand at different speeds, the noise disappeared, which gives me the impression that the bushing is not a problem. I reassembled the belt, I made it looser, more tense and the noise is there again. Could it be that the motors reflect this noise on the X axis? It’s a mystery.
Ok, thanks. The screws were very tight, too tight in my opinion. When I loosened them and left them like that the sound became softer. I wonder if something was damaged by this. The bearings themselves or their mounting.
You can try to loose small hex screws on left and right side of the printing head. It screws, as I understood, needs for tention of the belts xz core system.
But be careful: when tention has been changed, level relative to Z axis of hot plate will be changed too.

same problem and no reponse from Creality…
I have the same problem and the “customer Service” is really jacked up. Very slow or no response on email, the telephone answers is some language that I could not recognize and then after about the fourth try I got English then they hung up after about 5 Min of waiting. The chat box takes so long for them to reply that it times out. I am seriously considering sending it back. If I could only contact customer service.
I was thinking of giving up on the customer service, the first response came after 8 days where they requested more details even though I gave the order number etc. Then I sent a lot of pictures, receipt and the same video links you can see above and the response came after 11 days from different address only claiming that the videos are not available but not answers or comments to any of my questions.
What I can conclude is that DON’T order ANYTHING from crealitys own shop at least. The experience is so bad that I cannot recommend Creality and will move to other platform even though I started with Creality and have good experience of the products from past.
For the issue, I noticed that the sound goes away if I squeeze the rods together by hand so the sound is generated from bushings. The why is the question, is it defected bushings or rods or if there is play between them or some other gap out of tolerance.

I had the same issue with one of my two E3 v3 plus. I noticed that the belts on the one that was working perfectly were MUCH looser than the one with the ugly noise. Also, the first layer on the one with the noise was not exactly great, either. I manually loosened the belts (disregarding Creality instructons) to match the tension of my “good one.” This fixed the issue for me.

This worked for me too, but I have another problem after the belt loosens. When printing ends, the Z axis goes down when the printing is finished and ends up touching the finished part, as the axis is a little heavy, it can deform the already printed part.

Turn the printer over and tap on the bottom lid, where it bends and shoots off. Tapping lightly on it creates sounds that, at high frequencies, can resemble our vibration. It seems to me that when resonating with the x and z axes from the upper rack, the lower plate begins to rattle from the vibration of the steppers and the guide itself, because some users noted that when removing the straps, the sound goes away, which means that the steppers stop spinning and create a resonance on this plate. My printer is under warranty and I can’t remove the bottom panel. But if someone can check, please write back.

Update, I did a couple of tests, cut off a piece of the complete paralon and put it under this metal plate so that it supports it with a small margin and the sound would somehow become less. It seems to me that the vibrations come from it or from something else inside the case due to resonance, since they manifest themselves only at a certain speed of movement. It’s unlikely that it’s the head or the axes, they just create a resonance, and something inside is hammering against the body and transmitting it to the entire printer. At the moment, I adhere to this theory.
Could you solve it? Same problem here, and a lot of VFA at lower speeds
Loosen the belt, I’ll solve it! On the internet there is a tool that tensions the belt, use it to adjust the belt.
Link below this tool

VFA
[/quote]I understand, it is apparently correct, you can try to loosen it a little further than the tool reference and test to see if it generates the VFA, if it does not generate the problem is something else.
I loosened the belt a little more but the VFAs persists, its making me crazy
Привет друзья. я также мучался с проблемой артефактов и жуткого звука, всё решается заменой шаговых двигателей X и Z. Я установил на свой Ender3V3 plus двигатели Leadshine 42CM08 + новые качественные шкивы, после этого принтер стал просто прекрасным, тихим и без проблем с VFA. Ось Х движется очень тихо и плавно.
Двигатели Creality не очень хорошие, и дают резонанс

Hi friends, after hours of struggling with this machine, I still couldn’t figure out what the issue is. I’ve already tried all the suggestions you mentioned. The noise coming from the machine is extremely loud and unnatural. I’ve had this same model before, and it never made these sounds. Also, I’m getting very severe VFA, to the point where I can’t even print at low speeds.
If you have any suggestions or ideas, I’d really appreciate it. I tried loosening the XZ belts, but it feels like nothing changes — they just won’t loosen. The Y belt is properly tensioned.
Does replacing the stepper motor require reprogramming? Андрей_Богданов here said they replaced theirs and the results were great.
Can you guide us?
Thanks
The same problem here and no solution
