To Use a Gravity Point Mark Image in a Program
# Click Step Reference Image
• In the dispense program, insert one
Fiducial Mark command near the
beginning of the thicker line and one
Fiducial Mark command near the
end of the thicker line, specifying
in each the Mark No. of the Gravity
Point mark you created in the
previous procedure.
• Insert a Line Speed command and set the value at 30.
NOTE: This setting might need to be adjusted depending on thickness
of the line.
• Enter Line Start and Line End commands for the thicker line.
• Insert one Fiducial Mark command near the beginning of the thinner
line and one Fiducial Mark command near the end of the thinner line,
specifying Mark No. of the Gravity Point Mark you created in the
previous procedure.
NOTE: These Fiducial Mark commands can specify the same Mark No.
because both lines are similar in composition.
• Insert a Line Speed command that is double the previous line speed, so
that less fluid is dispensed.
NOTE: This setting might need to be adjusted depending on the
thickness of the line.
• Insert Line Start and Line End commands for the thinner line.
When the system dispenses on any line with fiducial offsets, it will align
the dispense in the middle of the line, regardless of the thickness or
thinness of the line.
NOTE: The complete example program is provided on the next page.
