Hi,
nice work but I don't think its going to work. When the controller detects a probe contact it will report back to Mach but it could take many milliseconds.
Mach then has to decide what to do and then instruct the controller, again with a delay of many milliseconds. The combined delay will mean most probably
that the probe gets crunched and certainly you will have NO accuracy.
How then does Mach probe, and probe accurately? You use a G31 command and the entire thing is handled by the motion controller which is near enough
to instantaneous.
Mach and Windows is not a realtime control system. It will respond to inputs in around 50ms, which is OK for buttons and on/off switches and things like that but anything
absolutely time critical it can't do. If the controller has been programmed to do whatever function is required all good, if not then you have to accept time delays
which usually wreck the function you are trying to perform.
