Python interface, relative/machine coords [SOLVED]

Hello

How I can know in python if I'm on machine or relative coordinate system?

Thanks

search through the active gcodes for the relative codes (G90/G91)
Unfortunately this can't be relied on in a running program because of the interpreter reading ahead of the actual machine.
There is a test branch to work on this problem hopefully merged in the future.

Oh wait now I think you mean you are referring to the DRO display.
You can't without being plugged into/modifying the program that creates this.
DRO display type is not a system wide setting it's a per screen setting.
linuxcnc has very few ways to communicate between screens.

Are you building a screen or building a gladeVCP panel? What screen are you using?
With more context I may be able to give more ideas.

I'm building a 7 segment display to show the coordinates

a physical one

Again without more info I'm guessing.

What screen are you going to use?
Some are easier to hack into then others.
It may require to customize the internal code of the screen, which is a pain if you update.
but all possible.

The screen is a series of 7 degment displays using max7219

the controller board is a teensy ++ 2.0

Currently I'm using Axis Gui
and using linuxcnc 2.8pre from github repos updated daily

using axis's ./axisrc file you could tap into the setting of coordinates.

for instance adding:
Will print test when you toggle # (coordinate display)
unfortunately it doesn't if you select using the menu and mouse.

Modifying AXIS is mostly undocumented and requires detective-ness and patients.

Ok

so there is no way to get it from a python component?

Thank you so much

Well AXIS is a python program but i guess you mean a separate program - No

g5x_index
(returns string) - currently active coordinate system, G54=0, G55=1 etc.

Thanks cmorley & bevins

I ended doing this:

as I only use G54 for now i'm done

Thanks again
