& Y Codes
The X & Y values in the Gerber file determine where the
aperture shape and dimension will be positioned and drawn. X & Y
values are used as coordinate pairs to determine where the light will be
exposed, using the D codes shapes (i.e. D10) and light exposure status
(i.e. D01, D02, D03) for drawing lines and arcs, as well as moving between
drawing entities.
Here are a few examples of using X & Y codes with D codes.
D10* {Select aperture D10}
X1000Y1000D02* {The D02 tells us that the light will be off, and we move to coordinate position X1000 and Y1000}
X2000Y3000D01* {The D01 tells us that we will draw (light on) to coordinate position X2000 and Y3000}
X5500Y100D03* {The D03 tells us to move to coordinate position X5500 and Y100 with the light off, then flash (turn the light on and off)}
