These statements are equivalent:
net a b1 b2 b3
net a b1
net a b2
net a b3
As long as 'a' is a signal and 'b1', 'b2' are pins
and you do not have more than one source pin.

Interesting...
So If I have just this one line:
net machine.is-on whb.halui.machine.is-on halui.machine.is-on
halshow shows this for the signal:
Signals:
Type Value Name (linked to)
bit FALSE machine.is-on
<== halui.machine.is-on
==> whb.halui.machine.is-on
But if instead I have these 2 lines:
net machine-is-on halui.machine.is-on
net machine.is-on whb.halui.machine.is-on
halshow shows:
Signals:
Type Value Name (linked to)
bit FALSE machine-is-on
<== halui.machine.is-on

No sure why halshow does that but halcmd prints the expected (identical) thing:
halcmd: net a hm2_7i95.0.inmux.00.input-00
halcmd: net a hm2_7i95.0.ssr.00.out-00
halcmd: show signal a
Signals:
Type Value Name (linked to)
bit FALSE a
<== hm2_7i95.0.inmux.00.input-00
==> hm2_7i95.0.ssr.00.out-00
(new session)
halcmd: net a hm2_7i95.0.inmux.00.input-00 hm2_7i95.0.ssr.00.out-00
halcmd: show signal a
Signals:
Type Value Name (linked to)

I think I have discovered the root of the problem:
if I do this all in JUST the WHB file:
net machine.is-on halui.machine.is-on
net machine.is-on whb.halui.machine.is-on
halshow shows the desired wiring.
But if I have the same exact lines in their respective separate main and WHB files, that's when the pin wiring breaks down.
So... maybe this has something to do with the way hal processes the net commands across files. I can say with certainty the two commands above on separate files = non-working WHB.

Sounds like the whb hal (postgiu.hal?) file is not linked-in
(I usually test this kind of issue by inserting a deliberate error in the file
to make sure its being used)

Hmmm... My ini shows this:
[HAL]
HALUI = halui
HALFILE = GantryMill.hal
HALFILE = custom.hal
HALFILE = toolchanger.hal
HALFILE = xhc_whb04b_6.hal
POSTGUI_HALFILE = gmoccapy_postgui.hal
POSTGUI_HALFILE = custom_postgui.hal
SHUTDOWN = shutdown.hal
In the end, because i used pncconf to generate the GantryMill.hal file I put this in my xhc_whb04b_6.hal file:
unlinkp halui.machine.is-on
net machine.is-on whb.halui.machine.is-on halui.machine.is-on
That seems to work. Jog dial works. Need to tweak the button functions, but I'll sort that out. Cheers!

having
net machine.is-on halui.machine.is-on
in GantryMill.hal
and
net machine.is-on whb.halui.machine.is-on
in xhc_whb04b_6.hal
would be identical
net machine.is-on halui.machine.is-on
in GantryMill.hal
and
net machine.is-on whb.halui.machine.is-on
in xhc_whb04b_6.hal
would be identical

I agree they *should* be identicial... weird thing is it didn't work out that way. It simply refused to work unless I put it all in the latter xhc_whb04b_6.hal file. Could be a version bug, who knows.

That doesn't make any sense.
It makes no difference when or from where a net command is
executed as long as the connected pins are present.
(at least in any version of LinuxCNC I've used)

I agree with you - it didn't make sense to me either based on my [admittedly limited] knowledge. I will do some more testing around this and document what I find.
Is it possible to see a log of what hal commands are actually executed in order on start? That might illuminate the issue.
