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:
<pyvcp>
<button>
<halpin>"z-touchoff"</halpin>
<text>"Z Tool Touch Off"</text>
<bd>3</bd>
</button>
</pyvcp>
