2.3.3 Product Setup Functionality
Parameter settings on the options page (Setup Product\Options\Stinger Dispenser) are derived
by trial and testing products prior to a production run. The user is provided with default values;
these are good for pre-production trials but may need modifying to suit a particular process.
2.3.3.1 Pre Separation Delay/Post Separation Delay
Pre Separation Delay/Post Separation Delay sets the time in milliseconds from when the dispense
valve is closed, to when the dispense nozzle moves back to idle height.
Pre Separation Delay sets the time taken when the dispenser auger valve stops rotating and the
dispenser rising to the idle position.
Post Separation Delay allows the user to set the time taken between the dispenser rising to the
idle position and when the camera moves.
This delay can be used to reduce adhesive stringing.

2.3.3.2 Dispense Separation Speed/Dispense Normal Speed
Dispense Separation Speed/Dispense Normal Speed sets the speed of the dispense lift actions.
Dispense Separation Speed during lift-off, following the dispense separation delay, the Z Axis
motor controller moves the nozzle from the dispense height to idle height. This can be any value
between 0.1mm/s and 20mm/s.
Dispense Normal Speed sets the speed of the Z Axis during all other movements.
2.3.3.3 Z-Axis Material Reverse Height/Z-Axis Material Reverse Speed
Z-Axis Material Reverse Height/Z-Axis Material Reverse Speed is used to set up the height and
speed of the dispense nozzle reverse movements. These movements occur sequentially. To dis-
able simultaneous lift and rotate set the parameters to zero.
mm
Z-Axis Material Reverse Height sets the z-axis/auger movement. If this value is greater than zero
there is a simultaneous lift movement combined with a rotation of the auger in the reverse direction.
Z-Axis Material Reverse Speed sets the speed of the reverse lift.

2.3.3.4 Purge After Downtime
Purge After Downtime allows a purge to be performed after the start of the downtime period. the
purge only occurs once, on pre programmed locations (sacrificial sites), during a single period of
downtime, to clear the Stinger nozzle.
2.3.3.5 Stinger Idle Height
Stinger Idle Height setting is the height the nozzle returns to after dispensing and before moving
to the next site. This position is automatically set.
2.3.3.6 Stinger Dispense
Stinger Dispense allows the user to enable or disable Stinger functionality.
