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.

Code:
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.

with slight modification of python script from  forum.linuxcnc.org/38-general-linuxcnc-q...lect?start=10#281577
it is working now at least jog selection

i don't know why but i thought that all UIs should use some hal signals for representation of data. So changing `halui.axis.x.select` should be used by UIs.

There is no need for a GUI to get involved with external hardware. Thats what halui is for.
When GUIs extend their scope, we get a mess with differing configs for no reason.
