Checking hal pin from NGC? was created by machete
Hello!
I am trying to folow this example, from here:
www.linuxcnc.org/docs/devel/html/remap/structure.html
But with any hal-pin it always show me "does not exist", or if i just try to debug it's value "######".
My version of LinuxCNC: 2.6.0
P.S. I want to have ability to do, or not to do part of NGC program (tool changing) depending on output pin of Classic Ladder.

You need to turn on the feature of reading HAL pins from g-code:

Thank you!
Is that correct?
[RS274NGC]
FEATURES = 8
enable #<_hal[Hal item]> readonly variables: 8
if set, the interpreter will fetch read-only values from HAL file through this special variable syntax.
Is that correct?
[RS274NGC]
FEATURES = 8

Yes, though you might want to use FEATURES=12 to get access to INI file parameters too.

Hmm... i wasn't able to get any #<_hal[hal-pin]> value before executing M66 g-code!
(i spent two days to understand that)
So, here is my correctly working NGC program for tool changing:

So, here is my correctly working NGC program for tool changing:
o<mytoolchange> sub
M66 P3 L0 Q0 (asking Classic Ladder is tool change needed?)
(flag from classic ladder)
(#debug, [5399]: #5399 - showing OK!)
(#debug, [skip-tool-change]: #<_hal[skip-tool-change]> - also showing OK!)
o100 if [#5399]
(debug, Skip changing tool!)
M6 (just legalize it for system)
o100 else
(debug, Changing.)
M5 (stop spindle)
G0 G53 Z75.1 (go to plane of Tool Magazine's clamps)
M64 P0 (enabling DO-CHANGE bit for classic ladder)
M66 P0 L3 Q2678400 (waiting 1 month for PHASE2 signal when)
G0 G53 Z205.3 (go back to left tool in the clamp)

M65 P0 (disabling DO-CHANGE bit)
M6 (acting loopbacks)
o100 endif
