Line Dispense Setup
Click Function
Sets how the system dispenses a line of uid. When dispensing high-viscosity uids, there is often a delay
between when the dispenser opens and when uid begins to ow. Use the Line Dispense Setup parameters to
compensate for this delay.
Parameter Description
Pre-move
Delay
The time the dispenser stays open at the start of a line before moving. This delay time prevents
the tip from moving along the line until uid is owing.
Settling
Distance
The distance the robot moves from the beginning of a Line Start before the dispenser turns on.
This distance allows the robot sufcient time to build speed and is used primarily to eliminate the
deposit of too much uid at the beginning of a line.
Dwell Time Delay time that occurs at the end of a line after the dispenser closes to allow the pressure to
equalize before the tip moves to the next point.
Node Time Delay time that occurs only for a Line Passing command. The dispensing tip passes through
the Line Passing point and waits at the Line Passing point, with the dispenser activated, for the
specied time period.
Shutoff
Distance
The distance before the end of a line when the dispenser closes to prevent excess uid from
being deposited at the end of the line, as shown in the illustration below.
Shutoff
Delay
The time the dispenser stays open after it stops at the end of a line.

Line End
Click Function
Registers the current XYZ location as a Line End point.
NOTE: The correct sequence of commands for a line is as follows: (1) Line Start, (2) Line Passing, (3) Line End.
Line Passing
Click Function
Registers the current XYZ location as a Line Passing point. This is a location on a line where the dispensing tip
changes direction, such as at the corner of a rectangle.
NOTES:
• The correct sequence of commands for a line is as follows: (1) Line Start, (2) Line Passing, (3) Line End.
• Also use a Line Passing point before and after an Arc Point command.
