The intenal signal is "motion.probe-input" which you should connect to
the probe switch.
a few months ago i wrote a little skript (tool-length-set.ngc) which
measures all tool lengths and writes the offset to the reference tool
into the tool table.
The reference tool is the first one in the script and has no tool number
(T0). The comments are mostly german but i think the script is not very
complex to understand. :)
Ciao,
