Again Mach is an open loop system and depends upon the accuracy of the screws and drive system. Coordinated motion is required when cutting arcs or circles. For example every 90 degrees on a circular cut one of the X,Y motors must stop and change direction. A tight mechanical system with little or no backlash is best whether open loop or closed loop. Pico Systems has a closed loop stepper board that runs under Linux CNC that is well thought out.
