halui.mdi-command-NN pins not showing up

Hoping someone can point out the probably obvious error in my configs that is causing halui.mdi-command-NN pins not to be created.  The halui component loads and the rest of halui's normal pins show up in the HAL Configuration tree; in the [HAL] section I have the HALUI = halui line; I've made sure the [HALUI] section in the INI file exists and that there are MDI_COMMAND entries under that heading, but still no joy.  Can someone see what I've missed? 



Thanks.


 

An MDI command can be executed by using halui.mdi-command-00
Here is an example showing how it 's done:

linuxcnc.org/docs/html/gui/halui.html
 

I’m aware of how it’s _supposed_ to work, my question is what I’m doing wrong in my configs that make halui not expose mdi-command-00 etc pins despite the presence of MDI_COMMAND entries in the [HALUI] INI section, and HALUI=halui in the [HAL] section?

Just in case you are not aware that in the # Syringe section in your postgui.hal everything regarding mdi-command is commented out.

Yeah, I commented those out to get LinuxCNC to start so I could look at the halui component in halshow, to see if maybe the pins were numbered differently than I expected or something. With those lines uncommented LinuxCNC won't start, since the mdi-command-NN pins don't exist.

Thanks for mentioning it though, I've certainly had forest-for-trees errors like that before where another pair of eyes spotted the problem immediately. 

There is  </vbox> missing at the end of of the .xml file

Thanks for the heads up! I don't think that would affect whether the mdi-command-NN pins would show up or not; even if don't load the PyVCP panel, I still don't see the pins exposed by halui.

There is something weird going on, I'm trying to duplicate the issue and some configurations mdi works and some do not.

Changing A to X and the mdi commands show up, changing back to an angular axis and the mdi commands don't show up.

Thats more than a bit wierd. 

Any clues from starting LinuxCNC at the command line? It sounds like it is giving up before parsing the MDI_COMMAND lines.
