Been throwing around the idea of building a cnc mill, the end goal is to hopefully be able to mill most materials (although i believe in this first iteration rigidity will be an issue)
I have compiled a list of components I believe I can cobble together, the feedback I'm looking for is if anything will absolutely not work together, if I am missing a component, and any huge safety issues.

Right now the problem I view is rigidity when working harder materials, I just do not have faith in the c-beams to hold up to the torques that the spindle and the nema 34's can apply to a workpiece. Also I do not have a vice selected right now that will be more of an addon.
I am hoping to use this as a platform to upgrade itself although I am now questioning whether I should instead build a plasma cutter to be able to cut a heavy frame for a future mill.
Thoughts, concerns, ideas?
