Yep happens on all machines over a certain length and it's a combo of vibrations through the frame and resonance from the screws. You should hear what a 10 x 5 sounds like in comparison. I'm currently just finishing one that's using rotating nuts and the X-axis still sounds much noiser than the Y-axis. I'll do a video when it's fit to be seen, it's still not fully dressed with wires and pipes hanging out everywhere.
