How to Use Marks or Fiducial Marks in a Program
Use the Mark command in a program as follows:
• To confirm the presence or absence of a workpiece.
• To confirm that the correct workpiece is present.
• To check the XY position of a workpiece.
Use two Fiducial Marks in a program as follows:
• To move the dispensing tip to a specific target area on the workpiece.
• To check the XY orientation of a workpiece. The system automatically adjusts the program to compensate for
any changes in orientation.
PREREQUISITES
The system is properly set up. Refer to “Setting Up and Calibrating the System (Required)” on page45.
