Might as well do another "experiment" which is virtually guaranteed to improve the sound: remove the rubber grommets and mount the mech rigidly

Avoid over-tightening any of the screws, while you're at it!

I just received the puck and the remote pcb. I hope to be able to start building soon, but work is pwning me hard this days...

Fully agree with above advice to skylab. I found that the results are very sensitive to any stress introduced into the frame. It is almost impossible to get perfect alignment using just bolts on a screw thread. The bolts will not be perfectly perpendicular to the their axes and certainly not in the same plane if there are more than two. We are talking microns here. I did not get it right until I had two spacers made from some aluminium tubing turned to equal lengths on a lathe. Even now I think I should get better ones made from a more solid material. If suitable mounting spacers are used, two diagonally opposed, then the frame can be screwed down onto them more tightly without introducing internal stresses. The difference that can be made by paying attention to this detail can make the difference between success and failure of your project.

Good work! Very nice chassis !
I would add a cover against the dust.
