That noise is the Z axis moving up one layer.
The noise of UM2 printing is something like this: dseeeeeee-dseeeeeee-CLUNK-----dseeeee-dseeee-CLUNK--etc.....end of printing: WHAAAAAAAAAUUUUAAAAAAAAAAAAAAAAUUUUAAAAAAAAAAAAAAAAAAAAAAAAAAAAA! (the z-axis again moving the bed down! You can hear it from the floor above).
Z-axis noise is definitely a point to improve on UM2 printers.

Hi,
I think the noise you are talking about comes from the z-axis. You can hold your finger on it to check whether the noise is synchron to the next layer.
