Traveling range
Gantry group 2
There should be 3 fiducials in the
traveling range (processing area)
for each gantry group.
The two placement areas are
combined to form a fiducial set
(6 fiducials).
Essentially:
The further the fiducials are apart,
the more accurately the PCB
position and the PCB skew can

antry group 2
There should be 3 fiducials in the
traveling range (processing area)
for each gantry group.
It is also possible to define fiducials
that apply to both processing areas.
The two placement areas are com-
bined to form a fiducial set with 4
fiducials.

2.7.2 Fiducial positions
One fiducial set for placement area 1 and 2. 2

One fiducial set in the overlap area.
Attention: Although this is possible, we do not recommend it because it can cause problems with
accuracy. 2
