Jogging with a four way joystick in normal jog-speed and rapid speed

Hello to everyone,
i'm trying to convert a Weiler 120 CNC lathe with LinuxCNC in a modern cycle lathe.
Actually i'm in the test phase with flying wired 7i76e.No motors connected (are in delivery from china).
All my wishes seems to work (four potentiometers, two mpgs, two direction switch for the spindle cw and ccw, a four direction joystick for manually movement of the two axis and a nice surface with the macros for cycles).
But my problem is, that the joystick have two switches for each direction. And i want to use both of them.
I want to use the first switch (it is snapping in) for slow moving depending on my potentiometer (for jog-speed). It is working perfect.
The second switch of each direction should be for fast jogging in max jog-speed. This switch comes in addition to the existing switch.
That means: one switch drives the axis slowly (working), two switches together should drive the axis fast (not working).
I don't know how to implement this in the HAL file.
Should i use one input for all four switches or one input for each to drive fast?
Any idea?
Thanks
Sascha

(sorry if my English is not so good, I am from Germany, Deepl is helping)

Additional Informations:
I'm using LinuxCNC in version 2.8. Axis is my actual screen.
And if it helps, i've attached my complete configuration.

Have you had a look at this component ?
linuxcnc.org/docs/2.8/html/man/man9/mux4.9.html to pick the speed either fast or slow.

The two switches on each axis go to the MUX to select the speed and to a OR gate to create the jog signal.

The input to the "slow input" to the MUX could from your logic, the "fast input" to the MUX could be fixed or created by manipulating the slow speed selection, either adding an offest or multiplication factor.

You could even write a simple comp that combines the two functions of the MUX and OR gate. Thereby only having to send signals to one "black box"

Hello BeagleBrainz,
thanks for jour Answer.
I will try it on monday. But it is very difficult for a newbee like me. All functions i used coming from other users, i‘ve put them only together.
Do you have maybe a example for me?
Sascha

No not really, but writing simple user comps are quite easy, if you have a basic knowledge of C you shouldn't have too much trouble.
The docs have some really simple examples that you can build on from.

I've tried some AND and OR additions:

# ALT:

net scale2 mux4.0.sel1 <= or2.1.out

net mpg-scale <= mux4.0.out
net halui.maxjoganalog <= mpg-scale => halui.axis.jog-speed

If my brain wasn't damaged by so much ANDs and ORs it should be working, right? Actually I can't try it, it is only some mental acrobatics.
The logics behind:
Switch X+ or X- or Z+ or Z- -> slow speed depending on my potentiometer
Switch (X+ and X++) or (X- and X--) or (Z+ and Z++) or (Z- and Z--) -> fast fixed speed.
X+ is the first switch of one direction for example, X++ is the second switch which switches additionally.

And it will not work.
First: AND and OR can only handle two signals. I've tried to fix this. Not the best solution, but don't know better.
Second: MUX4.0.in0 will have float:
setp mux4.0.in0 hm2_7i76e.0.7i76.0.0.analogin3
brings hm2_7i76e.0.7i76.0.0.analogin3 invalid for float. How can i convert this?
Third: How can i use signals from my inputs on several places?
I used .input-06 for moving the axis X in pos direction, but i need this signal also for changing jog speed.


Here is what i've now tried.

addf or2.0 servo-thread

addf and2.4 servo-thread

Maybe not of help to your particular application but this should give you the basic structure of a user comp
forum.linuxcnc.org/media/kunena/attachme...536/mpg_pendant.comp

Rather than using multiple components you can lump everything into a blackbox.

Have look through and I'll try and answer any questions.

Thanks for your help. I'll have a look at them
but actually (except the analog signal with the MUX2) it works fine.
It was simpler than i thought with MUX2 and only one of the signals from each direction from my joystick.
I can jog (actually with fixed values) with my joystick in all directions in normal speed and in fast speed.
Also the jog-display shows the value i choose with the joystick.
I'm very happy.

My last problem is to get the analog input to the MUX2.
I've tried this, but it will not work.

# Analog input
# net halui.maxjoganalog <= hm2_7i76e.0.7i76.0.0.analogin3 => conv_float_s32.maxjog.in (first try)
net convert conv_float_s32.maxjog.in <= hm2_7i76e.0.7i76.0.0.analogin3
#setp mux2.0.in0 conv_float_s32.maxjog.out will show "conv_float_s32.maxjog.in invalid for flow"
setp mux2.0.in0 100 i set it to fixed value to try the rest
#fixed value for fast jogging
setp mux2.0.in1 800

What mistake have i made?

My reading of he hal docs I would write the code as such
