That's the intention at first. The machine will be multi-use, so 3D
printer is next, and laser cutter later.

Homing is only to set the machine soft limits not for material touch off...

The touch-off butt
You can HOME anywhere but typically Z0 is all the way up. If you don't
have home switches then put some match marks on each axis and jog to
line them up then home the axis. After you home you "touch off" to the
material and you will be able to move within the soft limits of the
machine. You can
I don't have a homing switch on Z (yet), and even if I did, I need Z to
be set *very* accurately, so I think I'll need to manually set this
still. I need to try this to see if HOME_OFFSET is taken into account
without homing switches.

The touch-off is different as far as I've discovered so far. My min and
max Z is -25 and +100 in the .ini file. If I move to what the machine
thinks is 0 (wherever it was when the table booted up), and touch that

In my postgui.hal file I have the following
net z-fixture halui.mdi-command-08 <= pyvcp.z-touchoff
in my ini file in the [HALUI] section the 8th one is:
MDI_COMMAND = G10 L11 P#5400 Z0.0
in the [DISPLAY] section is:
PYVCP = hardinge.xml
In my hardinge.xml file I have:
"z-touchoff"
The Homing function is to set the machine 0 for each axis so soft limits
work and has nothing to do with setting the material offsets. Look at
G10 in the manual.

To me,
The PnP software I'm playing with (openpnp) is hardcoded such that Z=0
to clear the PCB and components. I don't have much of an option at this
point.
Haven't heard of PyVCP but looking it up now. Seems like it will create
it's own app (or panel). That might be a good thing actually, but for
Well normally the top of the material is Z0... and you use the touch off
button for that as it has nothing to do with homing.
Yes, you can add a PyVCP button to issue a MDI command to set the Z
material height.

(1) How do I tell LinuxCNC that I am at a specific position. So I set Z
to touch the top of a part and I want to tell it that's Z=-20. In Mach
3, I type the value in the DRO-displayed field.
(2) Extra credit -- is there any way for me to set the Z-pos
