How to select jog radio button on axis screen from hal? Or feed override?
I have tried to set those pins
axis.x.jog-enable
halui.axis.x.select
halui.joint.0.select

`halshow` showing that they are changed, but AXIS UI still doesn't reflect it.


For feed override
setp halui.feed-override.direct-value 1
setp halui.feed-override.count-enable 1
setp halui.feed-override.counts 8
setp halui.feed-override.scale 0.1


if i do setp halui.feed-override.counts 8 in halshow then it changes on AXIS UI, but why it doesn't work from hal file?

Also i have tried to do this from post_gui.hal same result
POSTGUI_HALFILE = postgui.hal

What is proper order to load those?

You might need to connect them to axisui pins

i have only limited amount of pins from axisui, and none of them seems to fit for this

setting scale before counts didn't help. In every thread that i have seen there always was mention about proper order of loading elements, so how i can be sure they are loaded in proper order?

Here is an example that decodes a 6 axis selector on a pendant that outputs  a 3 bit output (3 pins).  It uses a mux 8 and a select 8)
It also controls feed over ride and rapid override
You have to do a couple of data type conversions to make it work so its a bit long winded.

loadrt mux8 count=1
loadrt select8 count=1
loadrt conv_float_s32 names=pen-conv-float
loadrt conv_s32_bit names=pen-conv-s32

addf mux8.0                   servo-thread
addf select8.0                servo-thread
addf pen-conv-float           servo-thread
addf pen-conv-s32             servo-thread


#Axis Select (0=off, 1=x, 2=z, 3=y, na, 5=6, 6=4, 7=5) 
setp mux8.0.in0 0
setp mux8.0.in1 1
setp mux8.0.in2 2
setp mux8.0.in3 3
setp mux8.0.in4 4
setp mux8.0.in5 5
setp mux8.0.in6 6
setp mux8.0.in7 7
net mux8-sel0 <= hm2_7i76e.0.7i76.0.0.input-13
net mux8-sel1 <= hm2_7i76e.0.7i76.0.0.input-14
net mux8-sel2 <= hm2_7i76e.0.7i76.0.0.input-15
net mux8-sel0 => mux8.0.sel0
net mux8-sel1 => mux8.0.sel1
net mux8-sel2 => mux8.0.sel2

setp pen-conv-float.clamp 0
net mux-float <= mux8.0.out
net mux-float => pen-conv-float.in

net mux-s32   <= pen-conv-float.out
net mux-s32   => select8.0.sel
net axis-select-x <= select8.0.out1
net axis-select-y <= select8.0.out3
net axis-select-z <= select8.0.out2
net axis-select-a <= select8.0.out6
net axis-select-5 <= select8.0.out7
net axis-select-6 <= select8.0.out5

net axis-select-x => axis.x.jog-enable
net axis-select-x => halui.axis.x.select

net axis-select-y => axis.y.jog-enable
net axis-select-y => halui.axis.y.select

net axis-select-z => axis.z.jog-enable
net axis-select-z => halui.axis.z.select

net axis-select-a => axis.a.jog-enable 
net axis-select-a => halui.axis.a.select

net axis-select-5 => halui.feed-override.count-enable 
net axis-select-6 => halui.rapid-override.count-enable

and it is also change those radio buttons on AXISUI?
because i kinda use same approach and in the end i set `axis.x.jog-enable` and `halui.axis.x.select` and it works but AXISUI doesn't reflect it in radio buttons.

Confirmed the override problem.
Since AXIS is not in it's update loop yet when postgui is called, I'm going to guess it doesn't notice the change nor sync state late enough.

Linuxcnc it's self has no concept of 'selected' joint/axis - only the GUIs do - and each one does it differently.
linuxcnc does have MPG axis/joint enable but that is probably not exactly what you meant and is separate from any other jogging mechanism.

AXIS has no default way to select axes/joints externally.
When you select axes/jog with halui pins, it's halui that is directing the jogging not AXIS or linuxcnc

There are ways to add HAL pins to AXIS to select axes using an axisrc file, but that comes with it's own potential problems.
