Frame stability solutions

I was able to perform my first dry run tonight. I'm not sure how much one is suppose to be able to detect movement by touching the frame while the machine is printing, but it seems to me like adding rigidity would be helpful.

For reference, I already have a 6mm aluminum i3 rework frame. Let's say I have a desk that I absolutely don't care about. Is there anything to be gained from fashioning a bracket and bolting the printer to the table? Perhaps at the bottom and also along the top such that a "horizontal beam" is parallel to the Y axis?

Does this even matter?

Thanks

Bolting the printer to the table isn't going to do much but get the table moving more. The i3 frame should be pretty stable already, with the possible exception of the cut aluminium vertical piece. There's potential movement along the Y axis, but this can be dealt with by something like this: https://www.thingiverse.com/thing:100128
