    I was planning to build my CNC router from welded 100mm x 100mm x 6mm SHS steel utilizing a high side wall design so I could get the top rail mounting surfaces machined co plainer and also keeping the gantry pillars short.
    I accepted the fact that the machining of the rail mounting surfaces was going to cost a small fortune, about $600 Australian.

    Now I have to decide if the welded frame first needs to be stress relieved at about $850 plus about $1000 in freight.

    Would that budget be better spent constructing the CNC out of heavy 160 x80 aluminum extrusion?
