Calibrating the effective length

HEIDENHAIN only gives warranty for the function of the
probing cycles if HEIDENHAIN touch probes are used.
The effective length of the touch probe is always
referenced to the tool reference point. The tool reference
point is often on the spindle nose (and face of the
spindle). The machine manufacturer may also place the
tool reference point at a different point.
Set the preset in the spindle axis such that the following applies
to the machine table: Z = 0
