XHC-WHB04B-6 and LinuxCNC 2.9.1

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

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.
