Seeing values of gcode settings was created by diep

Hello, the active gcodes in the active gcode tab - what do i type in the mdi window or where do i click with mouse to see the value displayed for example of G64 gcode that is active?

Kind Regards,
Vincent

I am not sure that there is a built-in way to see the G64 setting.

I have looked at increasingly hacky ways to find it (numbered and named parameters, HAL pins, Python status) and I don't see it mirrored anywhere.

The next step would be to start from the other end and see if the data gets put anywhere in the code, but it is going to be a long and winding journey an I don't have time right now:

Looks like the G64 settings can be found in the 'settings' attribute in the python interface:
linuxcnc.org/docs/master/html/config/python-interface.html

Not a 'point and click' solution I'm afraid.

And you can run Python in the MDI window (I think...)

(python, print(linuxcnc.status.settings[3])

I would be absolutely astonished if that actually worked, though.

I thought Andy was right. But wait, there may be a shortcut. But it seems that the G64 P & Q Parameters are passed to the state tags structure
github.com/LinuxCNC/linuxcnc/blob/master...tion/state_tag.h#L96
and
github.com/LinuxCNC/linuxcnc/blob/master...ion/state_tag.h#L118
eg in fields_float[GM_FIELD_FLOAT_PATH_TOLERANCE]

Maybe Andy can tell you if that's accessible from the Python interface, otherwise you would need to add a pin for it in motion.c
github.com/LinuxCNC/linuxcnc/blob/master...motion/motion.c#L708
Good luck!

EDIT: Cross posted, heaps of options!

So at a guess, the field_float array is copied ot the Python Settings array as the field order is the same

Very cool! Thank Andy for getting state tags into the code base

The magic comment does not work.
'Nested comment found'
It seems that it does not like nested brackets in a comment.

It seems to be

(py, python code)

or

;py, python code

It calls code here:
github.com/LinuxCNC/linuxcnc/blob/2.8/sr...python_plugin.cc#L67

And multi-line python code can (probably) be passed using "\n"L www.programiz.com/python-programming/methods/built-in/exec

Though if the OP wants to do this a lot, a custom M-code might be easier.

If LinuxCNC is started in a terminal the MDI python method does write to terminal but requires a few commands:

;py,import linuxcnc
;py,s=linuxcnc.stat()
;py,s.poll()
;py,print(s.settings[3])

I don't know how to get it to appear in AXIS and I have not tried any other GUI's. I did attempt sending it to stderr but that didn't help.

;py,sys.stderr.write(f"{s.settings[3]}\n")

Thanks phil,
For output to axis add:

;py,import emccanon
;py,emccanon.MESSAGE(str(s.settings[3]))
