stacking mdi commands in 2.9.7 was created by radom

I made fresh install from 2.9.4 ISO then update & upgrade to 2.9.7 and you can add new mdi command only after the previous one has been executed
I though this bug was already fixed, can anyone tell me is this only problem with my config
thanks

I don't think it's a "bug", there does seem to have been some debate in the forum and GitHub as to the "correct" behaviour.

I'm a bit puzzled a this was supposedly fixed by
github.com/LinuxCNC/linuxcnc/commit/7852...1a3b13ca333d4e6d874f

removing this line #982 from 'axis.py':

    if running(): return 0

yet the line seems to be back in current 2.9:

Since this is a python file you could modify /bin/axis to fix this (you would need sudo rights to do this on a deb install)

I'll file an issue on github, thanks for reporting
