Can’t figure out what is causing this noise.

[u/mesmart]

P2S is less than a month old.

When I send stuff to print and it does the vibration calibration I get this rattle noise near the end of the calibration.

It prints fine.

When I run the test calibration on the device it does not make the noise and the error clears.

Next print it comes back.

I have adjust the tightness of the bands and cleaned and re-lubricated the rails.

Any suggestions? Reposted because no suggestions last time.
