Thanks, Ben, for interesting suggestions. I will try add something of this as far as possible .I do however have a few suggestions which might be useful for those of us that use touch screens...

Very nice.
One slight issue (Linuxcnc 2.7-pre6); if you change the values in the control boxes by typing in numbers instead of clicking on the up/down arrows, the new values don't get saved in the <machinename>.pref file.
They might not even take effect when directly typed in but I'm not sure on that and not in front of a machine at the moment to check.

This problem exists in PyVCP. I can't recall if it is also an issue with Glade, I vaguely recall doing something about it in my lathe UI, but can't rememeber which version.
There may be some clues here:

I fixed this for pyVCP a couple of years ago re spinboxes, when you hit Enter after entering a value, it updates the value.
(commit 4c092a8dfea9ed85d7d6d2388b9f9e04e51814a5)
However these are glade widgets, so no idea re them.

"hit Enter after entering a value" also works in Probe Screen.I fixed this for pyVCP a couple of years ago re spinboxes, when you hit Enter after entering a value, it updates the value.

I am trying this out on a virtual machine not connected to a cnc. using the (SIM) --> Axis settings. Here is my error at startup.
Previuosly had to add this to the display header to get it this far.
MAX_FEED_OVERRIDE = 50
Is it possible I do not have my folders in the right locations? Ill append the axis config file below.

Can I suggest a modest but potentially very useful mod for this?
A probe tip offset/compensation method.
I've bought a probe (admittedly not a Renishaw!) and getting the tip centered to any reasonable accuracy is turning out to be a right pain.
Given that the probe would always be mounted in the same orientation (not unreasonable as the cable kind of dictates a natural place and I'd mark the front of the probe body and always use that facing the front of the machine), I know that probing in -X it measures 0.12 less than +X, +Y some 0.08 more than +X and -Y 0.04 less than +X.
It's easy to measure the offsets by turning the probe through 90 degrees and probing a known face in +X so if I could enter those differences into the probe routines (it doesn't even need to be in the GUI, editing the .pref file or setting a value in the machine's .ini file would be fine) and the calculations took account of the offsets I wouldn't need to worry that the probe tip is not 100% on centre.
Any chance of getting this added? or is it already there? I see references to 'tool_offset[]' in probe_screen.py but that array doesn't seem to be set to anything (warning my Python skills are less than my levitation skills so I could be missing the blindingly obvious!).

You can probably do this as a tool offset (ie in the tool table) for whatever tool the probe is (mine is tool 99)
I have a button for M61 T99 G43 H99
And one day I will remember to have my probe-routines check that the tool number is correct.

Doesn't the tool table only provide for one offset per axis? or have I missed something?
If it is only one offset then that doesn't help when probing a corner or circle as that needs two or three offsets respectively (assuming +X is 0 ie the probe tip radius) and even for single axis probes I'd have to change it each time.
Looking at the code some more, the references to tool_offset[] seem to apply to X, Y and Z so that's not what I'm looking for.
However, probe_screen.py calls 'xminus.ngc', 'yminus.ngc' etc and somehow gets the result of the probe therein back into the Python code (probed_position_with_offsets()? is it the print from xminus.ngc that gets fed back into python? the python stuff doesn't reference 5061 or 5062).
When I get back in front of my mill, I'll try hacking xminus.ngc as, if my guesswork is right, a tweak along the lines of:
might do the trick.

Maybe I am the one missing something, but the offset between the probe ball and the spindle axis can be described by an X offset and a Y offset. If you insert the probe into the spindle and then G43 the centre of the ball will be where the encoders say it is.
Your changes to the probe routine will probably work fine too, though.
