I have successfully connected a touch probe to the accessory socket, but the coordinates of a successful probing are not as expected. I do this:
g0 z0
g31 z-0.5 (probe downward)
After the probe trips, parameter #2002 is supposed to be the Z coordinate of the location at the time the probe tripped (section 7.7.12 of the manual). And so I expect this command to do nothing:
g0 z#2002
If the program coordinates are the same as the machine coordinates, then the result of the g0 above is just a *tiny* movement, probably correcting for the probe having overshot or having backed off slightly.
But if the program coordinates are not the machine coordinates, the command g0 z#2002 causes a downward movement.
1. Is this expected operation?
2. Am I using g31 correctly?
3. What is the best way to get the program coordinates of the probing?
Thanks,
Kerry
