in the ini you typed MDI_COMMAND = G0 x0 y0 z0.
so i would write HOME_ALL = g0 X? Y? X? in my ini?
in the linking, it's mdi-command-00. i know it can't be capitalized, but it goes from -(minus sign) to _(underscore)

halui.mdi-command- has to be one of the MDI commands in the ini file.

But not halui pins.

John

does halui._____ have to be a command from the list of MDI commands?
as in G0 X0 Y0 Z0

Almost,

correct
.xml creates the button
custom_postgui.hal links the button

and .ini defines the button = not exactly, the ini defines the MDI command only so it has to be something that you can type in the MDI window to work as a halui.mdi-command-nn

net is a command = correct
remote-Home-All is the name of the button.(can be whatever name i want? ) = correct almost it is the signal name not the button name

halui.Home-All is the pin(don't know if halui needs to be there) yes, halui must be there and I don't think you can change the spelling to caps but not sure so best to just have halui.home-all

<= is the linking = incorrect the <= does nothing it is there to help/confuse humans only

pyvcp.Home-All is from xml file = correct that is the name of the button pin

The error is probably the caps in the halui pin name...

Take a moment and read this couple of pages it might make more sense now that you have done a bit of hal.

John

if i got this right;

.xml creates the button
custom_postgui.hal links the button
and .ini defines the button

net remote-Home-All halui.Home-All <= pyvcp.Home-All

net is a command
remote-Home-All is the name of the button.(can be whatever name i want? )
halui.Home-All is the pin(don't know if halui needs to be there)
<= is the linking
pyvcp.Home-All is from xml file

so far i have this;
=================================================================================
# Include your customized HAL commands here
# The commands in this file are run after the AXIS GUI (including PyVCP panel) starts

# MDI commands
# rapid to home button
net remote-rapid-home halui.mdi-command-00 <= pyvcp.rapid-to-home

# home all button
net remote-Home-All halui.Home-All <= pyvcp.Home-All
================================================================================
but it errors with halui.Home-All does not exist.

i know net starts it
net _______ halui._______ <= pyvcp._______
do these(net,halui,pyvcp) "HAVE" to be in the linking ?

If you don't have home switches you can't get the "Home All" button on the left.

However now that you have halui loaded some other options show up.

www.linuxcnc.org/component/option,com_ku...o,8498/lang,english/

I assume the halui.home-all pin requires you to have home switches but who knows give it a try.

change your

# home all button
net remote-home-all halui.mdi-command-01 <= pyvcp.home-all

to

# home all button
net remote-home-all halui.home-all <= pyvcp.home-all

and see what happens when you press it.

John

when i start emc, i have to home(zero) each axis.
i have to click on each one - x then "home axis", y "home axis", z "home axis"
i'm trying to be able to home all at once.
i did something before(in ini i think) that gave me a "home all" button on the left, instead of home.
but then i couldn't home each axis individually. so when i zero X, y and z had to be at zero. which is
not possible with me.(don't think it's possible for ANYONE:)

the <pyvcp> </pyvcp> tags need to only be in the .xml file once and wrap around all the rest.

As far as I know there is no G Code that will cause a "home all" to happen. What did you have in mind there?

John

cool i will.

can i get an example somewhere of more then on button ?

i have this in custom_postgui.hal;

# MDI commands
# rapid to home button
net remote-rapid-home halui.mdi-command-00 <= pyvcp.rapid-to-home

# home all button
net remote-home-all halui.mdi-command-01 <= pyvcp.home-all

but it tells me pyvcp.home-all doesn't exist.
i'm guessing i'm naming something in the second button wrong.

i have this in xml;

<pyvcp>
<button>
<halpin>"home-all"</halpin>
<text>"Home All"</text>
<font>('Helvetica',10)</font>
</button>
</pyvcp>

if i could see the pin naming format better, it would help.

Yes, as far as I know that is the way. Just remember to add the MDI command into the [HALUI] section of the ini. Let me know how it works.

John

:

THANKS

so they're three files i need to work with to get buttons ?
this gives me a great start.....THANKS

and can i add buttons(s) by

....... ....halui-mdi-command-01 .......
....... ....halui-mdi-command-02 .......
....... ....halui-mdi-command-03 .......
an so forth ?
as long as i have 'pins'

i'm trying to get it to home(i think of homing as zeroing XYZ)
without moving the table. is this possible with pyvcp ?

Ah, your missing the last bit to the puzzle.
In your ini file in the [HAL] section add

HALUI = halui

John

NP, REALLY appreciate the time and help !

Debug file information:
custom_postgui.hal:6: Pin 'halui.mdi-command-00' does not exist

can i add pin(s) by

....... ....halui-mdi-command-01 .......
....... ....halui-mdi-command-02 .......
....... ....halui-mdi-command-03 .......
an so forth ?
as long as i have 'pins'

Sorry, that needs to go in your custom_postgui.hal

John
