Remote gui

Now I wonder if its possible to run linuxcnc in commandline (without X started) and to have GUI like axis on other computer and communication over ethernet.

Yes. I sometimes do this, but not quite how you describe.

You can ssh into the linuxcnc machine and run LinuxCNC as a remote X application.

mill$ linuxcnc

Gives me the Axis GUI on the screen of my Mac in the house, but the software is running on the LinuxCNC machine in the garage.

More often, though, I set up and start the machine in the workshop, then call up a little window on the Mac screen to keep an eye on progress.

halcmd loadusr halmeter -s pin motion.program-line

motion.program-line shouws the program line (obviously) so you can see that the machine is making progress, but it also (and usefully) shows 0 when waiting for a manual toolchange or the program has completed or errored.

But how to avoid GUI on real machine and to have GUI only on "supervising" computer?

It depends on what you mean.

If you don't want any GUI code running on the LinuxCNC machine then you may have to use a non-GUI UI. You can actually use DISPLAY=halui in the INI if you want, and you get LinuxCNC with no GUI.

Rockhopper might be useful to you for the other half of the system, running remotely.

Or, maybe run "keystick" as the UI on the remote system (though the Keystick code still runs on the LinuxCNC machine).

What exactly are you trying to achieve?
