2. The workpiece is conveyed into the Pre-dispense Station.
A Stop Pin is engaged to stop workpiece transport.
A Board Sensor detects the workpiece.
The Lift Table rises to hold the workpiece in place.
Pre-dispense Station Heater Tooling, set at a programmed temperature,
heats the workpiece. The workpiece remains at the Pre-dispense Station
for a pre-programmed period of time.

The Vision System locates master fiducials on the workpiece. Fiducials are
located as reference points for the dispensing patterns.
The Dispensing Head moves in Z-axis and Height Sensor probe is lowered
until the Probe senses the substrate height. This establishes the dispense
gap based on the dispense gap setting in FmNT.
Flowrate calibration is performed.
