Thanks for your attention to this matter.
Let me know when a fix is available. For now, I'm getting abs_act_pos and subtracting half of pos_offset. When a fix is available, I'll go back to using rel_act_pos.

The patch has been pushed. I am not sure how healthy the buildbot is at the moment, though.
If you have a locally-compiled version of LinuxCNC then it is a fairly simple set of changes:
git.linuxcnc.org/gitweb?p=linuxcnc.git;a...1804877436def51de56c

I don't have a locally-compiled version of LinuxCNC. I was hoping that as some point I could just download a modified (compiled) version of linuxcncrsh. I'm not in any big rush -- it's not stopping me from working.

Hi Andy
However I named your diff linuxcncrsh.patch and ran patch -p1 < ./linuxcncrsh.patch from the root of the source tree and it patched and compiled fine
The resulting binary did work and below is the output from the same test I did previously
So it appears OK, the relative and machine positions are correct and the offset is correct at 10 not 20.
Well done
My binary attached below in case that works better on someone else's system
regards

The binaries did not work for me either.
Perhaps later today I'll have the time to download the sources and do the patch.

I have the sources downloaded and did the patch, and it now gives the expected results.
Thanks to all for your help!
