I'm trying to get a fusion360 WCS probing post-processor buttoned up.

control ver 2.34.

reading the v3 programming manual (I bought a copy and PDFed it here) and the RAP help shows that a G51 should be able to update offsets.

the v2 doesn't support the G51.X extras but does run the G51.

When I run the G51: the probe operation runs, hits twice, probe returns to start position but no offsets are reflected as updated on the offset page. If I exclude the H word the program offset (g92) is also not updated. the system registers page does show the hit at the correct coordinates.

test command line
Code:
g51 x-13.197 y-10.91 z-17 i0 j0 k0 h3 o2
. I would expect with `h3 o2` that program offset 2 would be set.

I'm clearly doing something dumb! Any help or pointers would be very much appreciated.
