Hi,
the ESS has a total of 51 inputs/outputs.
You could dedicate 4 inputs to Probe1, Probe2.....Probe4 for instance. Note that Probe1, Probe2 etc are Mach4 inputs.
How many of them you use, if any at all, is up to you. If you want to use G31.X probing commands then Mach will
look at ISIG_PROBEX as the probe contact event.
For instance:
G31.2 Z -5 F50 will cause your machine to probe in its current XY location to a lowest of Z= -5mm at a speed of 50mm/min.
Mach will monitor ISIG_PROBE2 for the probe contact event. I suppose you could use ISIG_PROBE2 as a signal to do something
else, turn a light ON or OFF say but why?
