I have a problem using lube.py
I followed the cmorley procedure:
" try this (depending on your file manager the tabs etc might be called diffeent but the process should be the same.
.
Find the lube.py file using the file manager and right click it.
select 'permissions' tab
select 'make executable' checkbox.

switch back to 'basic' tab.
look for 'location'
copy it to the hal file so it looks like this (obviously you will have a different path):

loadusr -W /home/chris/emc-dev/configs/sim/qtvcp_screens/lube.py

Chris "

but I still have the problem of "No such file or directory".
I've tried to place it in usr/bin like lubedude's procedure but I'm having the same problem.
Found file(REL): ./main.hal
./main.hal:5: execv(/bin/lube.py): No such file or directory
./main.hal:5: waitpid failed /bin/lube.py lube
./main.hal:5: /bin/lube.py exited without becoming ready
Shutting down and cleaning up LinuxCNC...

my hal file
loadusr -W /bin/lube.py
what is the cause of this problem?

Do you have a file named 'lube.py' in your '/bin' folder?

As said Aciera, you shouldn't have lube.py in /bin/ .
Maybe you would write ./bin/lube.py in case you are working in /usr and you placed the file in /usr/bin as you said.
/ mean the filesystem root, ./ mean "here"

Try this:

loadusr -W lube.py
or

loadusr -W ./lube.py
If that does not work, edit the lube.py file and check at the top there should be something like
#!/usr/bin/python
or
#!/usr/bin/python2
and change it to
#!/usr/bin/python3
save, try running LinuxCNC
