Is this probing for plasma ?

Yes.
Test video you see here:
www.xup.in/dl,15200380/plasma_kopf.MOV/
The hole on top is for the 12mm capacitive (or inductive) sensor.

I work with 2 dimensions ^^
measuretool.ngc

o<measuretool> sub

    ; setup
    G49 (cancel tool lengths)
    G91 (incremental mode)
    G28.1 (copy absolute coordinates into #5161-#5169)

    #1002=[-#5163] (probe depth)

    ; measure
    G38.2 Z#1002 F20 (Z probe)
    G92 Z-2.05 (distance switch_on to Workpiece surface)
    G90
    G0 Z1 (after probing move to 1mm up from workpiece)

o<measuretool> endsub
M2

This is very easy for the user.
It have 2 buttons. One for XY zeroing,
other for probing.
The solution of the problem "MDI mode" is here

why at all does your plasma use XY Zeroing
i got on all 4 Plasmas we use a Fix XY zero wher the sheet is fixed to and all programms use this zero

ok i only got 1x1meter sheets no inlays

but the Homing refers to this point and then Z touchoff as you do it
i

the Fix Zero makes life very easy
one button press and then run

Why are you not using one of the configs that have automated probe in hal ?

Choose one depending on your hardware.

Mostly we will not use XY-zeroing.
This is just so that you have the possibility, if perhaps even a workpiece is not in the corner.

@tommylight
That would have been a possibility, of course.
I have not seen the thread before.

if you are on THC
toms config changes on every M3 is a waist of time
with 100 M3 in files it is a nightmare on theroing up

It does not "changes on every M3", it does probe for material on every M3.
Here that is a must as the material used here is the bottom quality, so it warps a lot. Also i have some very fast Z axis that can do 6000mm per minute and have 28 cm travel ! :) Probe time = 1 second

I have seen people with 5mm bent table not doing probing at all as the thc jumps in and goes to the given Voltige down
within a mm of travel at 6m/min
even on Torch fire-ring startup at 5mm from material
