That is a very familiar sound to me. I had that problem for awhile too…
My problem was the print head rail had a loose bracket and it was creating lots of problems for me.
Take a look at this thread:
Is this buzz sound normal for 3d printing? - Snapmaker 2.0 - Snapmaker: where creation happens
Then I have this thread where i went into details on some efforts
Loose Linear Module w/ Workaround Attempt - Snapmaker 2.0 - Snapmaker: where creation happens
You may have a different module loose than the print head, but when it was the print head for me the sound was only occasionally where as when i traded rails with the build plate it was nearly constant
As such, a smarter idea would have been to trade with a Z since it moves the least hehe
After swapping rails, it was noisy as could be but at least i was printing well. However, by the time the replacement showd up the noise was violent and grindy like metal scraping (occasionally) and i had so much play it wasnt even funny.
You should try to gather up as much info as you can, pictures videos etc, email support@snapmaker.com asap to hopefuly get a replacement rail before the chinese new year.
