what I need is the number in the 5000 block, (or where ever it lives)

You need the value in HAL, so just use joint.3.pos-cmd
That won't jump around with changes in the co-ordinate map in use? G54
to G57 for example?
That, if not affected by map changes (and its not) until a move is done
ack the new map,
would be ideal.
It's in inches, going thru zero but not quite mid travel. and its seems
dead stable. I'll use it, but Z is joint.2,
not joint.3, :) which is the bs-1. for an A axis. I think I'm ready to
carve a new .hal file.
If the offset is linear it doesn't matter where the origin is, so you
could use motor-pos-cmd, but I think this pin will be consistent once
homed.
And LCNC remembers that even thru shutdowns. Should not need disabling
controls since Z
is the first axis homed just to stop tool breakage. That's simplifies
the .hal a bit.
I won't need the switching mux or lut5.
Thanks Andy. Take care and stay well.
