I have done some testing without my subscript, no loaded ngc-file, just with the MDI command field.
" G43.1 Z100 " -> TLO Z shows 100 on the axis display, the regular z-axis is then reduced by 100
" G43 " -> TLO Z shows 0, the the regular z-axis is then increased by 100
then i ve done a "G43.1 Z999" and wrote a test-script that prints #1 up to #5600 to stdout,
there was no parameter number that contains 999

I think I am seeing what I expect.
Do you at least see the DRO (in verbose mode, as shown) and #5403 match?

Sorry, meant to ask the OP.
I have a run across an odd situation with a G43 (in 2.7) and was curious if the two might be related.

What version of Linuxcnc are you running?
2.6.4 (as you can see in the picture).
I would be surprised to find that this has changed in 2.7, but I am not excluding the possibility.
Can you try the MDI sequence in my example and see what you get?

You are definitely on to something.
Using this test code with Z = 1 for tool 1 and 2 for tool 2:
I got this.

Meanwhile I figured out too that #5403 contains the value that ist _stored_ in the tool.tbl, like andy wrote in the last post. I my setup i am using a tool length sensor but i didn't saved the lool length offset into the tool.tbl. Tool length changes every time i change the tool due my tool holder. When I saved the G43.1 measurement - the #5403 is updated.
I dont want to save the tool length offset in the tool.tbl - but i need to check in my "tool measurement script" if there is a TLO Z (stored or not stored) because the _first_ tool has to be touched of to the surface by hand. When the display of the offsets is switched off - my script fails...
Is the _displayed_ TLO Z accessible in some other way ?
linuxcnc-version is 2.6.9
