I have this incredibly loud noise coming from my Y-axis. It doesn’t affect print quality, but it is horrible to listen to and really loud. It is present when the Y-axis moves at ~100mm/s and gets worse/louder as speed increases.
How can I mitigate this? There doesn’t seem to be any mechanical issues when I move the bed by hand, it is smooth and easy to move.

If you can, put your finger on safe to touch spots, to see if you can find where that vibration is coming from. Start with the stepper motor, or even the bed itself. (Be safe, don’t heat the bed). Super Light pressure should be able to feel vibrations, heavier pressure might temporarily make the noise stop, giving you hints at what is actually wrong.

Moving the bed through its full RoM by hand slowly, do you feel constant resistance? Is your motor even slightly loose? That can definitely amplify any motor noise. It’s probably worth lubricating your rails, I’m assuming you have something like a creality cr10? Here’s creality’s wiki for maintenance. White lithium grease in a syringe is my general use for printers, I do like 3-in-1 or another light oil for my Mk3s though, really easy to apply a light coat to the guide rods
I’ve suspected resonance in my z axis on my bed slinger, only shows up with large moves and higher ambient temps, and the sound is best described as a way louder stepper noise.

I’d check the bearings too.

My Anycubic does the same and i read from more people having this problem. You can losen the tension of the belt with the red screw infront of the printer. This fixed it for me.

Maybe too loose? Should be tightened completely and then one 360 degree turn
