/*==========================================================================
 * The sketch shows how to move more than one motor. 
 * 
 * If more than one motor is moved by one controller all motors will arrive at 
 * their targets at the same time. E.g., if the motors are part of a 
 * x/y transport system, the transport move on a straight diagonal line to the
 * target coordinates.
 * 
 * The sketch also shows examples how the motor properties are set up
 *
 * A 1/16 microstep driver is assumed. You probably want to adjust speed, 
 * acceleration and distances if you are using a driver with another microstep 
 * resolution.
