Hi,
I did check that thats why i posted the question in the forum
My ini has more but i copiued only this 3 sections
[DISPLAY]
DISPLAY = axis
EDITOR = gedit
POSITION_OFFSET = RELATIVE
POSITION_FEEDBACK = ACTUAL
MAX_FEED_OVERRIDE = 1.2
INTRO_GRAPHIC = linuxcnc.gif
INTRO_TIME = 5
PROGRAM_PREFIX = /home/tkamsker/linuxcnc/configs/Heiz400T-3WZW
INCREMENTS = 5mm 1mm .5mm .1mm .05mm .01mm .005mm
PYVCP = ToolChPanel.xml
[HAL]
HALUI = halui
HALFILE = Heiz400T-3WZW.hal
HALFILE = custom.hal
POSTGUI_HALFILE = custom_postgui.hal

[HALUI]
# HalUI-MDI-Befehle hier einfügen (max. 64)
# MDI commands
MDI_COMMAND = T1 M6 G43
MDI_COMMAND = T2 M6 G43
MDI_COMMAND = T3 M6 G43
MDI_COMMAND = T4 M6 G43
MDI_COMMAND = T5 M6 G43
MDI_COMMAND = T6 M6 G43
MDI_COMMAND = T6 M6 G43
MDI_COMMAND = T6 M6 G43

and The XML is an exact copy of that thread for the start

And the custom_postgui.hal is
# Benutzerdefinierte HAL-Anweisungen können nachfolgend angegeben werden
# Die Befehle in dieser Datei werden nach der AXIS GUI (und PyVCP-Panel) ausgeführt.
# MDI Commands
#net too1-1 halui.mdi-command-00 <= pyvcp.tool-1
#net too1-2 halui.mdi-command-01 <= pyvcp.tool-2
#net too1-3 halui.mdi-command-02 <= pyvcp.tool-3
#net too1-4 halui.mdi-command-03 <= pyvcp.tool-4
#net too1-5 halui.mdi-command-04 <= pyvcp.tool-5
#net too1-6 halui.mdi-command-05 <= pyvcp.tool-6
#net too1-7 halui.mdi-command-06 <= pyvcp.tool-7
#net too1-8 halui.mdi-command-07 <= pyvcp.tool-8


now commented out that i can work manually
So i see the 8 Buttons
My idea was that i do simply an Collet On and Collet off button which simply call M101 and M102
Then the T1 T6 buttons wich would Translate to Tx M6 <cr> o<ww> call <cr>
Where <cr> is carrige return
I wanted to stay verry simple

So the error
custom_postgui.hal:4: Unknown command 'net tool-1 halui.mdi-command-00 <= pyvcp.tool-1'

was not clear how to tackle it. Can i switch on debug or is it simply the wrong section for that command does it need to be set later or earlier ?

In my day profession i am a developer but i did so far spent no time in the code and i hope that this is not now necessary ;)-

So if someone already had similar issue or has an hint would be verry welcome ,..

Because when this is finnished (and i can dio the pcb i try ) then i might be able to finnish the arduino based pendant ,..
Where i have an working prototpye,..
thx

Hi

It's quite simple, I have copied all of Johns entry into sim files and the problem is that the <pyvcp> </pyvcp> tags are missing from the .xml file

Should be
<?xml version='1.0' encoding='UTF-8'?>
<pyvcp>

    <labelframe text="Tool Changer">
    <font>("Helvetica",16)</font>
    <hbox>
      <button>
      <halpin>"tool-1"</halpin>
      <text>"T1"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-2"</halpin>
      <text>"T2"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-3"</halpin>
      <text>"T3"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-4"</halpin>
      <text>"T4"</text>
      <bd>3</bd>
      </button>
    </hbox>

    <hbox>
      <button>
      <halpin>"tool-5"</halpin>
      <text>"T5"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-6"</halpin>
      <text>"T6"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-7"</halpin>
      <text>"T7"</text>
      <bd>3</bd>
      </button>
      <button>
      <halpin>"tool-8"</halpin>
      <text>"T8"</text>
      <bd>3</bd>
      </button>
    </hbox>
    </labelframe>
 
</pyvcp>

This is the running proof



Another benefit of always running programs from the terminal, you get to see all the error messages.

Good catch! I didn't even think of the pyvcp tags when I copied that part from the much larger xml file.

Did you put the MDI commands in the ini file in the correct place?

"unknown command" is a strange error message, as I would expect "pin not found" if it was a problem with the PyVCP or the MDI_COMMANDs.

You can check that the halui.mdi-command and pyvcp pins exist by using Machine->Show HAL Config to bring up the Halshow widget.
My suggestion is that they do.

I wonder if the problem is some sort of windows line-ending problem? Is the interpreter baffled by the "<LF>net" command?

You will just have to zip your complete config folder and attach it.

The code works, as demonstrated, there must be something in the way it is implemented in your configs which is causing the error.

(or as I have just seen Andy say, your files are littered with CR / LF or other control chars if done on a word processor)

BigJohnT replied the topic: Re:Tool Changer
A little grepping in the source finds this code that triggered the "Unknown command" error is in src/hal/utils/halcmd.c:
static int parse_cmd1(char **argv) {
    struct halcmd_command *command = bsearch(argv[0],
                halcmd_commands, halcmd_ncommands,
		sizeof(struct halcmd_command), compare_command);
    int argc = count_args(argv);

    if(argc == 0)
        return 0;

    if(!command) {
	// special case: sig = newvalue
	if(argc == 3 && strcmp(argv[1], "=")) {
	    return do_setp_cmd(argv[0], argv[2]);
	} else {
            halcmd_error("Unknown command '%s'\n", argv[0]);
            return -EINVAL;
        }

Don't know if this sheds some light on the picture...

That code is part of the command line parsing from halcmd, seems unlikely.

There are some others, if you do a case insensitive search, but equally unlikely.

I wonder if it isn't just a BabelFish, German to English translation thing?

Anyway can't do anything else without the configs, your code works fine, there is something else in the mix.

I did a case sensitive search to find the exact one with the "C" as you found out the case insensitive search brings up other hits.
