Motors have high pitch sound when enabled

I just upgraded my V-Core 3 from 3.0 to 3.1 and the enclosure kit.

After fighting a couple issues in the build I finally got it back up and running but noticed that it was pretty loud after homing. Kind of a high pitch whine and I feel like I didn't notice it before the upgrades.

I can get the sound to go away by disabling the x and y steppers. I didn't do anything to the motors outside of unplugging them and plugging them back in.

I think I remember some posts talking about motor buzzing due to an incorrect wiring diagram or something. Does that seem to be the issue I'm having?
