Wow didnt know that, so they`re not the same at all, oil for the first and grease for the lower one… check.
Thanks!

Yeah, I only figured it out after pulling the tool head apart.
Hola, pudo resolver?
tengo el mismo ruido. saludos
My v3 plus makes that sound on the x axis moves at slower speeds, have you tried fixing it?
I have the same issue on my ender 3 v3 plus. The travel on the x axis is noisy and vibrates. The vibration is worse at slow speeds. I think the worst vibration was at 100 mm/s. I used the orca slicer vfa test to see what speeds and along what axis I was having the provlem. Its definitely.happening at slower speed along the x axis. Its definitely NOT a normal behavior. I dont know why anyone would say that. I’ll check my bearings and rods. It is difficult to determine the source.
No I haven’t. It’s really not that loud.
Ive the same problem and only has 1d and 17h of use.
Tengo el mismo problema y tiene 1f 17 h de uso.
I have a same issuse.
Mine is new and about 3-4 hours print😐
I tried to adjust belts but nothing happened.
Same sound like scratching metal and grinding + abnormal vibrations.
I think v3 plus is a buggy machine🥲
if you run the machine in silent mode the noise is really reduced but the printing times gets doubled.
I have same problem. Anyone here who find the solution or source of the noise?
I have the same issue with a brand new printer, couple of days old. I had also used grease on the top carbon sleave bearing, but after seeing @sleewok explanation, I cleaned off the grease and lubricated with machine oil.
The sound it creates actually doesn’t sound like scratching but wobbling/vibrating like on old matrix printers. So I took the printhead apart and noticed that both top and bottom bearings wiggle slightly in the casing of the printhead if you grab it on the sides and try rotating it.
One interesting thing @sleewok mentioned is that the top sleave is tensioned by springs (plural). I only have one spring in one of the top bearing holes. The other spring hole is filled with some plastic blocker. I would appreciate if anyone would be able to clarify if there are supposed to be two springs or just the one.
Other than that, I tried adding some latex around the top bearing within the casing to stop the wiggling, but it turned out the bottom bearing is actually the one which wiggles in the casing. The two set screws behind the hothead as @sleewok mentioned, do not seem to do anything than just hold the bottom bearing in place. Whatever I did with those, the bearing still had some wiggle room in the printhead casing.
I’d rather say the top or bottom bearing should have had springs going against the other rod rather than applying tension on the side. Perhaps that would have compensated the vibration on low speeds where it obviously achieves a resonant frequency.
I have the same problem on Ender 3 v3 Plus.

Any news? Solution?
I had the same issue. My way to fix it: you need to find two small screws in front side of printhead holding lower x axis bushing. Untighten them to free the bushing, then use your fingers to center it position inside printhead. Then tighten them back. Mine was not factory centered and after these steps problem never came back.
