How to mount Epoxy Granite Machine to table?

Hello,

A while ago I built an epoxy granite router (arround 1000x800mm, ~350kg+) which sits on a "relatively sturdy" Aluminium extrusion table with some steel reinforcements.
I added mounting-plates with M10 Threads on the bottom, currently there are simple feet mounted and they are clamped to the table but Im looking for something slightly more professional and maybe also easier to level.
If its possible to also dampen some of the vibration (especially from abrupt acceleration) without loosing performance it would be a bonus.

How would a granite machine like a Datron M8 be mounted to the table? In case of the Datron I just know that the plate sits on three points on a welded steel-profile Frame but not If there are dampening elements between or how it can be levelled.

Excuse the probably noobish question but I couldnt really find a proper example of how to do this.

Greetings,
Max
