I realy appreciate my U1, in one month I have printed with success many models but … there is an unpleasant noise caused be vibrations during printing. This sound is high-pitched like plastic or polystyrene. It occurs during left to right mouvement even when the printer is stopped as you can hear in the short video.
Do you have plans idea to reduce or stop this inconvenience ?
Are you sure you’ve removed all the transit packaging?
Yes I think so ! No tape or foam or cardboard remaining
Open a ticket:

I will open a ticket as soon as I am back home (in seven days!) to get my S/N.
You can place it directly on the floor and see if the noise persists. It might also be coming from your table.
I would try to isolate it to a region of the box, or even better to one or a couple of parts. That would make it much easier. Applying pressure on various parts, manually moving the gantry, sliding the wires, etc. might get some clues.
The noise is not directly linked to the movement of mobile components, as it happens when I move the printer frame when it is switched off. I will test it with the printer on the floor, as you suggested, Simon, to confirm that it is not related to the table, but I have no real doubt.
I suspect that two plastic parts are touching and rubbing against each other. I need to do investigations !

Okay, if you encounter any strange issues, you can submit a support ticket to report them.
You can submit a ticket at the same time in case the technical staff or fellow users in the forum don’t respond promptly.
While I relocated the printer today, I noticed the same notice on mine. So I started checking it out. By the time I kinda figured out what was going on, it got the same symptoms as the video above.
In my case, the back panel was rubbing. Taking it off was a quest by itself. You will see various spots where it is rubbing and the white plastic makes it easy to track them. Attached are some photos.
If it’s not rubbing against the frame, then chances are the clips that hold it in place are squeaking.
Thanks Ray for the feedback. I’m eager to get home to see if I have the same problem. Did you follow a specific procedure to remove the back panel?
There is a guide here: https://wiki.snapmaker.com/en/snapmaker_u1/troubleshooting/u1_xy_motor_replacement_guide
If you have the same issue as I had, you are interested in detaching the back panel. To my experience, the disassembly felt quite friendly, you just need patiente.
The noise problem is fixed !
After more than a week out of my home, I was finally available today. I removed the sides and rear covers, which immediately eliminated the noise. I’m not entirely sure which component was misaligned, but everything was fixed by unscrewing the USB card and removing the rear cover.
Thanks a lot @Ray for your fair advise. The first part of the Snap procedure you shared was very helpful. About one hour was necessary (without the calibration) as I prefer to go step by step.
I can’t understand why the link above to the guide on panel removal is marked as a ‘Solution’.
It’s certainly not a solution to the squeaking, just a method of investigation.
It was the solution for my problem and it is why I flag it as Solution.
Probably the root cause is an improperly installed rear cover and the corrective action is to take it appart and put it back together properly.
