axis-remote howto

Hi,

I'm using LinuxCNC 2.7.14 with sim/axis_mm configration.
I try to load my ngc file at the same host by:

axis-remote my.ngc

and I got error message:
no application named "axis"

Use "ps aux | grep axis" and I got the following processes running:

There do have a process "axis" running.
That's the problem ? Thanks a lot.

OK, I know how to fix the problem now.

The axis-remote error message:

no application named "axis"

comes from Tkinter's (Tk) "send" command which rely on X server to exchange message between two Tk's applications.

I got above error message because I run linuxcnc at DISPLAY localhost:11.0 and axis-remote at DISPLAY localhost:10.0. I use two terminals login to CNC host via "ssh -Y IP_of_my_CNC_host",

If I login via GUI and run linuxcnc and axis-remote both at DISPLAY :0, then axis-remote run perfectly.

If I use only one terminal login to CNC host via "ssh -Y ...". Run linuxcnc at background, "linuxcnc my.ini &" and then run "axis-remote" from the same terminal (DISPLAY :11.0), it's OK too.
