Calibration
Gun Compensation (optional)
For high speed and precision applications.
NOTE: Before entering gun compensation values, make
sure the gun-trigger offset has been entered on Event
Map, page 29.
Gun compensation ensures higher accuracy of bead
placement. Begin with Recommended Values below
and adjust according to Calibration Routine.
Recommended Values
GM-100: 5-10 ms
GS-35: 10-20 ms
Unknown, other: 10 ms
Calibration Routine
1. Navigate to Gun Setup, page 33.
2. Dispense desired pattern (program contained within
the pattern controller).
3. Measure the error distance between the dispensed
pattern on the product and the desired pattern.
4. Adjust open/close compensation values according
to the following Gun Compensation Table and
Gun Compensation Formula below.
5. Repeat steps 2-3 until desired pattern achieved.
