>If frame: The biggest acoustic panel would be your print bed, so any excessive vibrations can travel to it, mess up the print, etc. Best to find out where the source of the vibrations are, then to minimize it. A more elastic frame has more disadvantages to it than a stiffer, Al frame such as yours. Your frame simply transfers vibrations easier and has less dampening. Stick with your frame, tighten everything and make sure it's secure.

It isn't always noisy, only at certain speeds, which is why I think the bearings are resonating rattling. When the printer had no belts installed the movement was really smooth, nothing was sticky except the Z axis (which happens to be silent, except for the motors).

Frame is tight, everything is secure, etc. I'm ordering a big PSU and some filament to start printing, if the rattling causes too many artifacts I guess I'll swap the bearings for those graphite-coated copper bushings, or maybe igus bushings
