Dispense End Setup
Click Function
After dispensing a dot or line, it is often required to raise the tip a short distance at a slow speed. This allows the
uid to cleanly break free from the tip to prevent it from being incorrectly applied. The parameters for Dispense
End Setup affect how far and how fast the tip raises after dispensing.
Parameter Description
Retract Low Speed
The speed (in mm/s
2
) at which the tip raises after dispensing.
Retract High Speed After the tip raises the amount specied by Retract Distance at the speed specied by
Retract Low Speed, the tip continues raising to the Z-clearance height at the speed (in
mm/s
2
) specied by this setting. The purpose of specifying a Z-clearance height is to
allow the tip to raise high enough to clear any obstacles it encounters on the way to the
next point.
Retract Distance The distance (in mm) the tip raises after dispensing.
