Like I said the name can be anything you like however the tag must be correct or it is ignored by EMC.

[SECTION]
TAG = value or name as appropriate for the TAG

ok thanks. i thought the postgui told it "WHEN" to load the file.
i have all tags/name correct and still get "pin " pycvp......" does not exist.
maybe it's not possible to simulate mode ? but i can make the
buttons/leds and see what i have. everything works great as long
as i don't link the pins.

You can do anything in a sim you want. My guess is your not linking the pin in the correct place. You can't link a pin until it is created. That is the whole purpose of the POSTGUI_HALFILE tag. When you have a hal file after the POSTGUI_HALFILE tag it is not loaded until the GUI is done loading. Your pyvcp pins are created when the GUI loads.

My guess is your trying to link a pyvcp pin but your not doing it in the file pointed to by your POSTGUI_HALFILE tag.

So a sample [HAL] section might look like this:

[HAL]
# this file is the main hal file and is the first to load. 
# you can't link anything in this file that is in the other files 
# as they are not loaded yet nor can you link to a pyvcp pin in this file
HALFILE = myconfig.hal

# this file is loaded after myconfig.hal so it can link to anything in
# itself and anything in myconfig.hal file.
# you can't link to a pyvcp pin in this file either as they have not been  created yet.
HALFILE = mysecond.hal

# this file is loaded after the gui is done including pyvcp
# so any pyvcp pins MUST be linked in this file
POSTGUI_HALFILE = mypostgui.hal

Again, the file names can be anything you like and mean nothing to EMC.

Thanks.
i had
HALFILE = postgui_custom.hal

instead of
POSTGUI_HALFILE = postgui_custom.hal

i had asked about "post" but as file name, not as a tag.
works not but i get the homing at X 1600 again.

Thanks Again !!

(at work now)

(making a DRO)
with the feedback, relative and commanded position pin. i get the same number.
if i have offsets, shouldn't one(or two) be different ? in Axis, if i have a
z offset of 1", "my" readout reads .9 while running and z is at -.1".
i tried all three pins and i get the same number. is the pins suppose to
be connected to another pin as well ?

offsets;
X - .125
y - .125
z - 1

Anything that takes a u32 in.

Use this reference for halui till 2.5 comes out, I updated the pins to show what type they are... dang it must be confusing not knowing what the pin takes...

www.linuxcnc.org/docview/devel/html/man/man1/halui.1.html

What are you trying to do? If you want to show the current tool use a u32 number display.

feedback, commanded and relative. all give the same output. i'm using number display
to get the reading.

halui.axis.N.pos-relative

axis.2.joint-pos-fb

<hbox>
<label>
<text>"Z:"</text>
<fg>"midnightblue"</fg>
<font>('courier 18',18)</font>
