PCB height offset [mm]
Set an offset value as a nozzle descending distance based on the upper
surface of the PCB in the component placement section.
This offset value applies to all components in the pattern program.

Notice
Be sure to set the same reference as the input and output
machines.
If a reference different from the input and output machines is
specifi ed, PCBs cannot be produced correctly.
Note
When a different reference is specifi ed in the pattern program and the
program is to be used for this machine, be sure to change the reference of
this machine to the different one.
