HEIDENHAIN only gives warranty for the function of
the probing cycles if HEIDENHAIN touch probes are
used.
You can identify the intersection of two straight lines
by holes or studs and set this as the datum. For each
straight line however, probing must only be with two
identical touch probe functions (e.g. two holes).
