Pin 'halui.jog.0.minus' was created by nicokid
Hi,
I started to play again with LinuxCNC after a couple of months ago I mistakenly destroyed my configuration (git clone in mi home :( )
Now I get this error:
Pin 'halui.jog.0.minus' does not exist
In effect I have this Pin setting on the first row of my hal file:
net my-jogxminus halui.jog.0.minus <= pyvcp.x-minus
But as we see from my configuration halui is activated:
...
[HAL]
HALUI=halui
HALFILE = stepcraft-840.hal
#HALFILE = custom.hal
POSTGUI_HALFILE = postgui_call_list.hal

[HALUI]
MDI_COMMAND = G54 G10 L20 P1 x0 M100
...
in effect on the function halpr_find_pin_by_name (hal_lib.c) there is no trace of pin halui.jog.0.minus.
What did I do wrong?
Thanks, Nicola.

Which version of LinuxCNC?

In Master the pins are now halui.joint.0.minus and halui.axis.X.minus depending on what you want to jog.

Hi,
thanks for your answer :cheer:
I use the git version. In fact I had suspected this thing but looking on the web I did not find any reference to this change. :blink:
I think I need of halui.axis.X.minus, I want to try this: linuxcnc.org/docs/2.4/html/hal_pyvcp_examples.html
So instead of halui.jog-speed should I use halui.axis.jog-speed?

The pins are all documented here:
linuxcnc.org/docs/devel/html/man/man1/halui.1.html

But be aware that halui is _not_ realtime. If you are using physical buttons then it is better to use motion pins where possible:

Uhm...I do not see anything useful in motion. :dry:

P.S. halui.axis.x.minus must be used with the lowercase x

The manual page 793/794 shows jog instead of joint. Should that be changed?
ie should a command such as halui.jog.0.plus
be changed to halui.joint.0.plus ??
After reading this thread, I changed from ...jog.. to ...joint... and it solved my problem.

Yes, it should be changed to mention both the axis and joint versions of the jog pins.
The offending text is here:
github.com/LinuxCNC/linuxcnc/blob/b948db...rc/gui/halui.txt#L76
And needs to be changed to match the definitive list here:
linuxcnc.org/docs/devel/html/man/man1/halui.1.html
