5.2 TEACHING DISPENSING POINTS
To start dispensing, dispensing points must be located and taught. Dispensing points can be
located in two ways:
•
Using the nozzle tip;
•
Using the laser pointer.
With the first method i.e. using the nozzle tip, you can elect to invoke the height sensor or not.
However, the height sensor must be used in conjunction with the laser pointer in teaching
dispensing points.
To teach dispensing points with the laser pointer:
1. First, ensure that the tip to probe offset has been setup (Refer to Section 4.1.1.1).
2. Before programming, turn the laser pointer on:
a. Using the PDA, select “Program” from the “Main” screen.
b. Tap the top left-hand corner of the Program screen and
select “Util” from the menu bar.
i.
Select “Toggle Laser”. This will turn the laser pointer
drive on.
3. Establish the origin of the program using the laser pointer.
4. Insert a height sense instruction as close to the first dispense
point as possible. You may choose to use the probe or the
laser pointer to teach the height sense location. If you choose
the latter,
remember to check the “Teach with Laser Pointer” box.
5. Teach the dispense points using the laser pointer as you would using a nozzle tip. Use the
dispense gap for each dot/line type to determine the z-height of the dispense point/line.
6. When all dispense points have been taught, return to the program origin and re-teach the
origin using the nozzle tip (instead of the laser pointer as you had done in Step 2 above).

8.
The Program window is where points are inserted, deleted and
edited. This is the main programming window. Now you are ready
to insert dispensing points into your program.
