Hi guys, I after a little advice from some of the builders on here. I'm sort of new to the whole cnc thing but I'm having a go at designing something on fusion. I am making a gantry to span 1200. What would be stronger.. 2x c-beam with 2 pieces of box section steel 40x20 mm x 1.5mm along each recessed area or 3x v-slot 8020 fastened together. My gantry plates are 10mm thick aluminium. I am using steel In the base area so its gonna have some weight to it....and its gonna be driven with ball screws. Looking at 566oz nema 23. (4Nm) Many thanks Mike
