Using the probe to locate a part that was "casually" loaded into the mill. P9811 single touch top of the part for Z, then P9814 find center of a bore to set X and Y. I then use P9842 to touch two points along the left side of the part and set the angle for rotation.
Run several tools/ops everything lines up as expected. I use G69 to cancel coordinate rotation so I can run P9814 again to inspect the central bore and verify it is in spec. Part looks good so far, so I carry on and load the next tool but! when it goes to its first position I can tell it is no longer positioned using the G68 rotation despite containing the command

Code:
Start with P9811
Then P9814

Here is some code doing some cutting

Here is the P9814 inspection cycle

G68 G90 X0. Y0. R[#194]
M8
G1 X1.675 Y-1.43 F500.

I had a hunch that #194 was being overwritten when I re-probed so I saved it to a local variable before the inspection, and then reset it after but that didn't work.
What gives?
