The system dispenses at the programmed site. Any offset between the pro-
grammed site and the material is the equivalent offset in the Y plane. Program
the parameter to compensate for this; it can be any value between
-5mm and +5mm.
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.
Set the measurement option to measure only (on a single site).

If more than one site is to be utilised and an image is available, select Load

Purge Station
Location
This parameter sets the location at the front of the rising table where the purge
station is placed. At the start or end of a production run, the user may request
a purge. Purging ensures that the flow of adhesive is continuous and homoge-
neous. The purge station contains a pot that collects the purged adhesive; the
purge station can be located on the front left or front right corner of the rising
table.
