Stell frame cnc 1500X1000. Adjustable table your opinion please

Is there any need for the bars connecting the legs at the bottom. I'm constructing mine at the moment, interested in the replies.

Actually no need, that's what i said before. Or they cut be cut in 2 and raised higher at the middle of the M, that's what i suggested before.

With 80x80 profile or bigger the machine will not twist , so no need for triangulation on the bed itself. remember that the spoilboard willnot permit eventual twist there.

However for the sake of absolute rigidity i would have soldered additional plate vertically along the center beam of the bed itself , that will strengthen immensely the bed

PS. option 1 looks perfect
