Can you post the code that creates the buttons? I think that's the main issue
here. As mentioned before, there are all sorts of G-Code subroutines in the
nc_files folder but getting away from using the 'command line' so to speak is
the general idea.
My issue was I have the HB04 Pendant. I also have in the pyvcp-panel.xml file
hal pins described.
<vbox>
<relief>RIDGE</relief>
<bd>6</bd>
<button>
<halpin>"rapid-to-Z-home"</halpin>
<text>"Rapid to Z Home"</text>
<font>('Fixed',16)</font>
</button>
<button>
<halpin>"rapid-to-XY-home"</halpin>
<text>"Rapid to XY Home"</text>
<font>('Fixed',16)</font>
</button>
</vbox>
In the postgui_call_list.hal I had
#net remote-rapid-to-Z-home halui.mdi-command-16 <= pyvcp.rapid-to-Z-home
#net remote-rapid-to-XY-home halui.mdi-command-17 <= pyvcp.rapid-to-XY-home
From what I understood from the documentation I then add two lines
# add halui MDI commands here (max 64)
# MDI_COMMAND = G0 Z0
# MDI_COMMAND = G0 X0 Y0
Which are assigned mdi-command-16 and -17 because the layout2.inc for the HB04
has
[HALUI]
# these are examples, edit as required:
# a halui hal pin is created for each MDI_COMMAND below
# halui.mdi-command-00, halui.mdi-command-01,... etc
MDI_COMMAND=G0 X0 Y0 Z0
MDI_COMMAND=(debug, example: mdi-01)
MDI_COMMAND=(debug, example: mdi-02)
#03 M110: clears notifications
...
#15
MDI_COMMAND= G10 L20 P0 C0
However that didn't work. So I postponed work on that for other stuff. But I
would like to get it working and I would like to create a few more buttons.
