Strange noise on the Y axis

@OnefinityCNC could you tell me what this noise might be and how to fix?

I’ve tried several times but your file will not play on my PC.

Looks like it doesn’t work with edge but should work with Chrome.

Anyone? Anyone? Bueller?

Sounds like something is loose and rattling? Given that it seems to happen at a regular cadence, that might suggest something related to the ballscrew.
