The ARRAY command specifies the grid size and interval for the array module. Briefly, this sets up a grid of points that can be traversed automatically with simple TTL control or with the RBMODE or AIJ commands.

The size of the array is Nx by Ny points, with points spaced apart distance Δx and Δy (expressed in millimeters). The location of the first point in the array is set with the AHOME command. Small tilt corrections can be included using the T=tilt angle in degrees from the X-axis. The actual Δx and Δy for each move will be modified to account for the tilt angle.

Without arguments, the AR command starts self-scanning of the array. When the stage arrives on target, it will delay for a period of time set by the command RT Z=time_delay before continuing on to the next position. It is possible to repeat the array using the RM F byte.

Whether a raster or serpentine pattern is used is set using the SCAN F setting (default is serpentine).
