z height probe

Hi,
I have a lcnc 2.9.2 running a basic router using parallel port. I'm trying to set up a z-height probe. I have tried several configs with the same error.
"custom_postgui.hal:6: Pin 'halui.mdi-command-00' does not exist".


#########custom_postgui.hal#######
# Button for automated Z Touch Off with plate
net ztouch halui.mdi-command-00 <= pyvcp.ztouch


########router,ini
HAL]
HALFILE = router.hal
HALFILE = custom.hal
POSTGUI_HALFILE = postgui_call_list.hal

[HALUI}
MDI_COMMAND = O <z_touch> CALL

any ideas on what I'm doing wrong?

thanks
 

  uploaded the configs.
