Hello!
In my attempts to reduce operators' errors due to leaving machine in
joint mode after homing all joints, I am trying to create a button in
Axis GUI that would switch to world mode. I am trying to add it right
next to "Home axis" and "Touch off" buttons in "Manual Control" tab to
make it as convenient as possible - press "Home All" and then "World
mode".
The reason for this is that I am getting sick of customer complaining
about "why are there those 2 modes and why can't it switch them
automatically then, none of our existing machines has such a
weirdness". There are hundreds of employees for that client and I have
no idea, how many of them have to work with that machine (they are
constantly rotating from one task to another), I suspect that it is
more than 10, but I have no way to check and they would not tell me.
There is a small instruction attached to machine about the basic steps
to get it going (including a sentence in bold of _mandatory_ switching
to world mode after homing all joints), but apparently they do not
seem very eager to read it and they keep ignoring my reminders about
the purpose of that instruction.
I tried classicladder for automatic switching to world mode after all
joints are homed. I can get the logics correct and it actually works
correctly. But the thing is that it is all fine until LinuxCNC
finishes running a g-code file - Axis GUI will set it to maual/joint
mode as Axis GUI was never told to be in teleop mode - neither Shift+4
nor View -> World mode was pressed and there is no HAL pin that I
could trigger from classicladder for this purpose...
I am blaming Axis GUI, because, when classicladder triggers
halui.mode.teleop pin, joint numbers in DRO and on Manual Control tab
switch over to axis letters, and machine behaves correctly -
kinematics are applied etc, but when I open "View" menu, I see that of
those 2 radiobuttons at very bottom - "Joint mode" and "World mode",
the bullet is still next to "Joint mode". So after running a g-code
file is finished, it switches from "auto" to "manual" mode, but
remains in "joint" mode", just as the bullet next to "Joint mode" mode
tells it to do.
So I copied both axis and axis.tcl files in their respective
directories, renamed them to cnc and cnc.tcl respectively, set the INI
file to use cnc for DISPLAY and started playing with them in "monkey
see, monkey do" manner - trying to copy the code that creates existing
buttons and rename appropriate parts. I gave a name of "world" to that
button and kept it in the same $_tabs_manual.jogf.zerohome frame,
where "Home axis" and "Touch-off" buttons already reside.
The thing is that I am receiving this error startup of LinuxCNC:

I suspect that this is the crucial line:
_tkinter.TclError: invalid command name
".pane.top.tabs.fmanual.jogf.zerohome.world"
What is puzzling me is where does "fmanual" part of that string come
from? Searching both usr/bin/axis and usr/share/axis/tcl/axis.tcl do
not show such a word, so I am out of any ideas, where to look.
I would appreciate any pointer to the cause of this childish mistake
that I am making here.
