Stell frame cnc 1500X1000. Adjustable table your opinion please

[ba99297]

BA 99297 I'll say it again to be clear "Any of the designs will be strong enough" so if any more focus is needed then I'd direct it to reducing resonance rather than strength.

Dean or anybody else could you please suggest me a link ( or links) where i can read about resonance dampening basics ( i mean what i should avoid in order to reduce resonance )
So far ( tell me if i am wrong ) i realize that low mass and symmetry amplify resonance is that correct?

Oh when I said about unsupported edges I meant you don't have any members to support the Bed base material at the edges. On your designs the edges between table supports won't support the material or any sacrificial material. It may seem a small detail but it can make a difference and for the little extra material/work it's not worth not doing IMO.!

Now i understand what you mean but i didn’t say that vertically to the table beams i will put t slot aluminium profile ( a friend of mine who makes solar parks on the houses roofs has many meters of them)
