Excessive Y motor vibrations
I tried searching for this but all I found was issues related to the bed itself, I don't believe this is my case. I have excessive vibrations (stealth mode) on my Y motor at certain speeds. Most of the time it's really quiet, but this one is annoying and I think the vibrations actually transfers to my print quality.
Any suggestions on how to eliminate the vibrations? Please see this video where I just slightly press the Y motor with my finger during a print. Touching the bed or any other motor does not eliminate the sound, and I can really feel the vibration go away as I push the motor.

The 4 screws holding the Y motor and motor mount could be tightened just slightly, about 10-15min each, this seem to have a big impact on the sound. For future reference...
RE: Excessive Y motor vibrations
Here's a thought. I eliminated my prominent Y motor noise by changing my Y motor mount. The stock mount leaves the motor a paint coat thickness away from the back frame. Certain movements cause a ton of resonance because the motor vibrates and that then bounces off the frame like a guitar string. You can try a zip tie around the motor so it contacts the frame more firmly, but beware the zip tie hitting the bed at min Y. Another solution is fold a piece of paper or plastic and slip it between the Y motor and the back frame. Or change the motor mount with a different one that doesn't squeeze the motor right against the frame.
