Thank you for answer.
I made fresh installation of 2.7 version.
I started Stepconf and there wasn't option to import mach fconfiguration...
I would be grateful for making me a conversion.
There you go, you would have to be running the latest buildbot version of LinuxCNC. For sure when 2.7.0 is released it will be in that one. I expect that real soon.
Thank you for answer, I have installed 2.7.9 pre6 and there is not option.
File you added in attachement is btw the same file I was posting.
Would you like to add converted file?
