I wan't to get from ini file value of maximum speed for setting jog speed . As in the basic tutorial .

Also QHSpinbox I would like to save last value to some file that in next turn on, it will load values from that file.

Does it's possible to do this?

For saving persistent values have a look at github.com/LinuxCNC/linuxcnc/blob/b8ce6c.../persistence.py#L122

And for reading the INI file could this be useful I think: github.com/LinuxCNC/linuxcnc/blob/b8ce6c...y/getiniinfo.py#L242

In forum.linuxcnc.org/gmoccapy/40709-gmocap...lock?start=30#201950 you find an example how to use this.

Thanks Hansu for your answer. Please give me more information where I can connect this python code? I've never used gmoccapy.

It is not only for gmoccapy. What GUI do you use?

I use QtPyVCP, there is main file .py where I add functions for buttons.

Ok what stupid question of me as your post is in the QtPyVCP sub forum :silly:

So you just have to import the libs like
from gladevcp.persistence import IniFile  # we use this one to save the states of the widgets on shut down and restart
and create a IniFile object and so on...

I copied to directory with main file.py
persistance.py and getiniinfo.py.

in main file i added
import persistance.py
import getiniinfo.py

And also line
from gladevcp.persistence import IniFile
But I really doesn't understand from what directory file is imported.

and visualisation doesn't load.

File Name: mainwindow.py
File Size:4 KB

But really I don't know logic of execution of QtPyVCP, I write to this file functions that should be executable when buttons pressed,
