Calibration and Adjustment 5-3
5.6 Calibrating the Camera
"
NOTE This procedure assumes that the dispensing system has been powered on, that FmXP is
running, that a substrate is available, and that the camera has been focused. The camera is
self-calibrating when using the calibrate button from the Setup Vision Window. The
software makes a pixel count comparison to machine units by moving away from the
taught image by a known value, finding the image again, and assigning a pixel-count-to-
machine-unit value. With this value established, the vision system can accurately find the
substrate and dispense at the correct location (provided the vision target image is within
the field of view).
"
NOTE If the camera is ever refocused to accommodate a different part height, the calibration
routine MUST be run again.
To calibrate the camera:
1. In the FmXP Programming Window, click the
Load a Board
icon.
!
The conveyor will transport the substrate to the dispense station and the lift mechanism
will lift it off the conveyor belt.
2. In the FmXP Main Window, click on
Configuration > Setup Vision
