Teaching Tip to Probe Offset
This is an optional function. You will need to teach the dispense tip to probe offset only if you
intend to use height sensor commands within the program. It is recommended you use the height
sensor if your application requires very small dots or fine lines. The tip to probe offset allows you
to teach the height difference between the tip and the height sense probe (which is essentially also
the surface of your part).
To teach the offset:
(1) Tap "Offset" under Valve #1 label in the Valve screen.
(2) To jog the dispense tip to the surface of the part, tap "Jog"
located at the top right of the screen. The Jog window
appears. Now, jog the dispense tip to a point on the surface
of your part.
Refer to
Appendix A
on detailed jogging instructions.
(3) When the desired location is reached, tap "OK".
(4) Tap "Teach" corresponding to instruction 2. The machine will
raise the Z-axis and advance the probe.
(5) Tap "Jog" again and jog the height sensor probe to the
same surface point. Tap "OK".
(6) Tap "Teach" corresponding to instruction 4. Your machine
now knows the XYZ offset for the current tip location.

WARNING!
Do not toggle the height sensor probe when the Z-axis is lowered;
this could cause damage to the machine and/or the part.
Tip:
The minimum tip-to-probe offset is 6mm. This is an approximation
of the distance the probe must move from surface contact to tripping
the sensor (i.e. surface detection) without crashing the tip.
