Stell frame cnc 1500X1000. Adjustable table your opinion please

[ba99297]

So far i understood that i should go even with all steel or all aluminium gantry, as combination of these materials will be a little tricky.
I will ask one more time and if somebody reading the thread i will be glad to hear his opinion. In what directions i must have the ability to adjust
FOr example if i go for all steel gantry, all parts welded and epoxy leveled for y axis rails, also epoxy leveled for the plates that will be bolted on the carriages what are the spots that should not be welded but bolted in order to have the ability to adjust?

Thanks
