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 tool reference point at a different point.
