Overview for Using Eight Trig Marks in a Step & Repeat Program
The following tasks are required to use the Camera Trigger, Trig Mark, and Rectangle Adjust commands to create
a Step & Repeat program that (1) causes the system to check the XY orientation of each workpiece in an array and
(2) to adjust dispensing accordingly:
• Creating and saving mark images on each side of a rectangular area on the workpiece. For each mark, you will
need to know its Width and Height values.
• Setting up the search range for each selected mark in the horizontal planes and then for each selected mark in
the vertical planes. See the illustration below for an explanation of the location of horizontal and vertical marks.
• Correctly entering the Camera Trigger, Trig Mark, and Rectangle Adjust commands in the dispense program.
