Hi, I don't see it as a challenge. Current machine have 0.025mm resolution at the outer edge of the table(260mm diameter). I think it is possible to build a 400mm diameter table with stepper motor. Any bigger table would require a slow operation or a high speed servo motor to get enough precision and speed. It is still not impossible. With a good servo motor you can have 2000mm diameter and good enough rpm.
