Giant 20' x 3' x 2' router build

i have posted a few more pictures bellow you can see i have all ready braced the corners of the table area which improved it a lot and stopped any movement in that area. I could brace it more underneath but i think the flex is coming between the top of the table and the top of the verticals. would filling the extrusion help with dampening any of the vibrations or flex down? would it be a good thing to do any ways?
I will have to maybe look into bolting it to the wall but i would like to see if there was any way i could improve it before hand using other methods.

I could probably put plates in the corners of the verticals above the table as well but they would have to be taller than wide so they do not interfere with things on the table.

I have adjusted the belts a bit and just pulled them hand tight before any signs of flex from the screw so will leave it like that at the moment many thanks for that info i was originally assuming they had to be pretty tight to work.

While we are here were is the best place to source the cable and steppers from as i am going to be needing a fare few meters in total.

best regards charlie
