The structural basis was implied to be robust, reliable, with all parts easy replaceable and accessible, and of course with affordable price. Your control electronics gives dominant tone to whole project and perfectly handles all assigned requirements. In short, in my tests stepper motor control unit SMCU3 in idle regime drives machine up to 25 m/min (in software limited to 15 m/min for all three axes), when following contours up to 8 m/min, in multi-hour everyday work, with countless repetitions, and in workshop environment with temperatures above 30 °C, also exposed to EM and RF interferences. Furthermore, test are performed with different types of plasma systems of both modern and older generation.
