'module' object has no attribute 'get_value'

Hi to all,

I have a problem wiht the command "hal.get_value", when I run the python script I get this error:

in <module> x= hal.get_value("x-pos-fb")
AttributeError: 'module' object has no attribute 'get_value'

Please write soon!

can you post all the code you used?
There are other commands that need to be called before that works.

There are my python code and the postgui hal.



However, I may have figured out what the problem is. The "hal.get_value ()" command works in LinuxCNC version 2.8.1 but not 2.7.14. I guess this command only works in newer versions, doesn't it?

However, I found the "s.actual_position" command in the documentation which also seems to work in version 2.7.14. If I understand correctly, this command reads the linuxcnc status and I can update the "current joint position" with the s.poll () command.

I will write a post to help everyone who has problems with these things!

Thank you all!

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.
