WARNING
Incorrect use of G38.6 can damage the probe and the item being probed, and can cause injury. Make sure you fully understand the probing process and take extreme care with this command.1. How it works
All coordinates used by G38.6, and all values written to the file, are working coordinates. A probe input must be assigned, and it must change from Low to High when the probe triggers.

3. Example
N10 G1 X20 Y10 F1000 N20 G38.6 Z-3 F100 N30 G0 Z2
If the probe doesn't trigger before Z−3, the machine stops, a Probing Error alarm is shown, and this line is written to the file:
Probing error at: 20.00000, 10.00000
