You should be able to do that. I was using Axis when I built this but is should work for you also. I just set the touch-plate on top of the stock and touch off by pushing a button on my touch-plate. Pushing the button causes the execution of this gcode.
Code:
<pre>
o100 sub
G20
( Set current Z position to 0 so that we will always be moving down )
G10 L20 P0 Z0
( Probe to Z-.5 at F2 [Uses machine units, I work in inch, this is meant to be slow!] )
G38.2 Z-.25 f2
( Set Z0 at point where probe triggers with offset of +1.008 [this is the thickness of my touch plate. You must adjust this for your plate / setup] )
(G10 L20 = Set Coordinate System // P - coordinate system 0-9 0 = Not active)
G10 L20 P1 Z1.008
( Rapid up to Z.5 above the material )
(G10 L20 P1)
(Use machine coordinates)
G90
G53 G0
(Incremental mode)
G91
(Rapid Z up 1 inches)
G0 Z1
o100 endsub
</pre>
In my .ini file
[HALUI]
MDI_COMMAND=o100 call
In my pyvcp-panel.xml. I used this before I had the physical button.
<?xml version='1.0' encoding='UTF-8'?>
<pyvcp>
<!--

<button>
<halpin>"oTouchPlateProbeButton"</halpin>
<text>"Touch Off Z"</text>
<font>('fixed',10)</font>
</button>
</pyvcp>
