Oh boy am I truly glad I am not a statistic! So the solution to the statistical dilemma is to put a mark on the shaft and bearing housing. Since we know how many mm the table moves per steppermotorrevolution we travel a multiple of that distance And the stepper shaft will be in exactly the same position on either end of the travel if all is right.
