This is where people get confused. you can't connect computer chips pin to pin. You have to use a wire or solder trace.
so with lcnc components, you replace the wire with a signal which can be whatever name you like.
To me it always makes it clearer to do it on two lines to make it clearer, particularly when starting out.
the <= and => are not required, they just are designed to make the meaning clearer by showing a direction (eg input or output)

# create a signal from an output pin
net plasmac:laser-switch <= qtplasmac.laser_on
# connect the signal to an input pin
net plasmac:laser-switch => hm2_7i96.0.ssr.00.out-01

That is why I find it easier if it is all on one line, that way you know it is all in one place.

I think its easier for novices to understand on two lines.

But my one line didn't make it to his hal file. I nearly did it on two lines but I was lazy and did it Phil's wayThat is why I find it easier if it is all on one line, that way you know it is all in one place.

Probably because the same net is in both hal files...

If this is for a laser then I would suggest:
comment these four lines out in PLASMA.ini file:
delete this line in custom.hal:
add this line in PLASMA.hal from:
after starting linuxcnc go to the parameters tab and set the offsets for the laser, then the laser button will appear in the dro frame.
linuxcnc.org/docs/devel/html/plasma/qtplasmac.html#qt_laser
linuxcnc.org/docs/devel/html/plasma/qtpl...l#peripheral-offsets
comment these four lines out in PLASMA.ini file:
BUTTON_10_NAME = ZERO ON\LASER
BUTTON_10_CODE = G91 G54 G1 X-49.15 Y-8.35 F1500 \ G90 \ G10 L20
BUTTON_11_NAME = LASER
BUTTON_11_CODE = toggle-halpin laser-switch
delete this line in custom.hal:
net plasmac:laser-switch => hm2_7i96.0.ssr.00.out-01
add this line in PLASMA.hal from:
net plasmac:laser-switch <= qtplasmac.laser_on
after starting linuxcnc go to the parameters tab and set the offsets for the laser, then the laser button will appear in the dro frame.

Thanks Phil & Rod,
Total newb error I'm sure.
I have made the changes.
# ---PLASMA OUTPUTS---
# ---all modes---
net plasmac:laser-switch <= plasmac.laser-on
# external output signals
# --- LASER ---
net plasmac:laser-switch => hm2_7i96.0.ssr.00.out-01
I now get the following error.
"PLASMA.hal:58: Pin plasmac.laser-on does not exist"

Needs to be in postgui file because the pin is created in the gui.

If i put that line in the postgui file i get the same error.
This laser is a sighting laser. Just so i can see where i'm going to be cutting. NOT A CUTTING LASER. it is run from a relay activated by the MESA7i96 through one of its outputs.

then press the laser buttonm on bottom right and see if it lights up in hashow

Comment out the offending line and check in halshow the pin exists. You need to have laser offsets in your ini file for the pin to exist but i thought I saw you had that.If i put that line in the postgui file i get the same error.

Oops postgui is correct
it needs to b qtplasmac.laser_on , you have:
# ---PLASMA OUTPUTS---
# ---all modes---
net plasmac:laser-switch <= plasmac.laser-on
