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 N_fast by N_slow points, with points spaced apart distance Δ_fast and Δ_slow (expressed in millimeters). By default X is the fast axis (where most movements occur) and Y is the slow axis (with periodic movements), but this can be interchanged using the SCAN command (e.g.
SN Y=1 Z=0 will make the fast axis the 2nd axis on the card, the Y axis usually, and the slow axis being the 1st axis usually X).
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).
