16. The camera axis moves the unit to the right hand edge of the board. This is the Range Posi-
tion where the unit performs a Range Check.
17. The nozzle moves down, either 1mm or 1.5mm dependent upon which Stinger option is fitted,
from contact height.
18. The nozzle moves up through contact height to 1mm or 1.5mm above contact height. This
completes the Range Check.
Board Clamps may cause boards to bow slightly in the centre.
This may cause the measurement to fall outside the 0.1mm minimum Z Axis contact position.

The feeler gauge thickness is the equivalent of one step of the Z Axis stepper motor. It is essential
that when setting this contact point no board deflection occurs.

For non-automatic calibration options, the user must set the idle height next. For automatic cali-
bration options, the idle height parameter has been programmed in Setup Product\Options
\Stinger Dispenser and the unit can track this value above contact height. Stinger can track the
rises and falls on the product surface within the range check limits.
2.8.2.2 Stinger Laser Offsets X and Y
This parameter sets a factor to compensate for any offsets of the nozzle to laser, in the X and Y
planes, at the point where the laser actually measures. This can be any value between -5mm
and
5mm
. As with the calibrated offsets, a deposit point is marked on the calibration board. The offset
is set to zero and a deposit is made; the difference between the deposit centre and the laser centre
is the amount of compensation to be set.
