I am in the process to build my CNC. Now I am wondering how I could find the error of my CNC when finished. I had the idea to use a steady and leveled laser and a moving light Sensor clamped in my Router. But I guess there are existing ways to do it. I assume that my machine is leveled and squared after I finish building it. So that I only expect an error from irregularities in my steel beams.
Size of machine will be 4000x x 1400y x 250z
