I have been researching what cnc controller to purchase to build a cnc Plasma/ Router table and have not found one that I like. I want to use one table but be able to do either plasma or routing. I am lost when it comes to the electrical part of designing something like this. Would a Pokeys 57 be a good choice? I want to use a THC with the plasma and will probably expand the router later on to have a VFD controller. I want to run closed loop nema 23 motors, unless there is a better option. Would Linux be the preferred method of trying to achieve this setup? If so what all would I need to purchase? Would I need a Linux based computer? I am trying to keep cost down as much as possible, right now I am guessing it will cost me about $3500 to build this system. I am slowly buying metal to build the table itself, the table will be a 4'x4' table with rack and pinion drives for the X&Y axis, Z will be a ball screw set up.
