Hello Oliver,
I think we should stick to English so that everyone can follow along!

Your detailed instruction has ultimately led to the fact that it runs!!!

I have it now with:
python3.9 -m pip install viaconstructor
to get it installed.
the important thing was --> puthon3.9 -m !!!

after that there was still a problem with the plugin:
"xcb"
but i could fix it with the command:
sudo ln -s /usr/lib/x86_64-linux-gnu/libxcb-util.so.0 /usr/lib/x86_64-linux-gnu/libxcb-util.so.1
//forum.qt.io/topic/93247/qt-qpa-plugin-could-not-load-the-qt-platform-plugin-xcb-in-even-though-it-was-found/110

The only thing I could notice now is that I have no icons in the tool column!
what can be the reason for this?

i still searching for a clean solution with the icons,
normally, viaconstructor search for it in:

/usr/data and /usr/local/data

but on some systems it's on a different location.
you can search for the icon flip-y.png in you filesystem and copy the folder to one of the known locations.

and/or tell me where the icons are installed on your system, than i can add it to the search list

Great job!

the folder "data" has ended up in  
home/cnc/.lacal/

I have now copied the folder "data" to "usr" and the symbols are there!

I copied the folder with the following command:
sudo cp -r /home/cnc/.local/data[here is a space]/usr/

I think it is important to show the steps so that also not experienced Linux users can see how to do it.

Where can I specify that my zero point is on the machine table?

i think the icon path is fixed in the next version.

# Where can I specify that my zero point is on the machine table?
What you mean ? your zero-z-point is the table ?
there are no setting for this :(
I set always the Zero point to the top of the Workpiece.

If you have zero on the table, you must also enter the height of the workpiece in the cam !?!?

If you explain it to me in more detail, I can include it

For me, and I'm sure for others as well, there is for example
G54 Z0 on the machine table.
Yes, so the workpiece thickness would have to be specified in the cam.

I measure the tool length automatically against the machine table.

If you could add that, then that would be great!

Hope this will help, i have no better idea at the moment to implement this feature, but if you have a better, tell me

 
python3.9 -m pip install viaconstructor --upgrade
# new version is: 0.3.7
 
This will only add a 'G54 X0.0 Y0.0 Z9.0' line to the gcode output

The line 'G54 X0.0 Y0.0 Z9.0' does not work.
does not work it makes no sense!

You can't assign any parameters to G54!

There should be an input field for the workpiece thickness.
The machining depth would then have to be subtracted from this workpiece thickness.
If I make for example a subprogram routine for NGCGUI
I use for the workpiece thickness a variable with which afterwards in the g-code is worked. Maybe something like this is possible?

It would be great if you could choose whether "Z0" is machine table or workpiece surface, for users who touch your workpiece surface.

I hope it is okay if I note something?

somehow I still do not quite understand the G54 command,

I thought I can set the offsets over it and a G0 Z0 drives then not to the table but to the new offset.

It is no problem to offset the gcode data, but for that, i need no G54

Correct !
G54 was also just an example of the coordinate system and is not needed . It was apparently confusing!
