System Design

As stated earlier, the laser beam only moves up and down. A mark is made by moving the Diamond back and forth, as well as left and right while the laser beam is moving up and down. In addition to left, right, back, front, and up and down, the Diamond can be rotated to expose various sections of the girdle during marking.

The left and right motion is called X-axis motion. The back and forth motion is called Y-axis motion. Up and down is called Z-axis motion. Rotation is called U-axis motion.

X and Y-axis stages are the largest and most critical to the motion system. The typical characters made are less than the width of a single human hair. The motion system must be able to move in steps over one hundred times smaller than the width of a single human hair in order to make smooth and legible marks.
