'module' object has no attribute 'get_value'

I am working with a 5-DOF robotic arm.
In the lab I'm working in, they use the old version because they have had problems installing the new one.

I agree with you, I will stress to my colleagues to update it to the latest version.
However, I'm afraid the .ini file won't work. In fact, I read in the wiki that in case of updating the .ini file must also be updated but there are no details on how to do it. Do you have any suggestions?

Thank you.

The major changes in 2.8x from 2.7x were to better support robots and gantries.

The required changes are documented in section 3 of "Updating Linuxcnc" in the docs.
But, in general, the "update_ini" script should run automatically and make the required changes for you.
