QTDragon stop & pause run

Shutdown_check must = True for preference saving to happen.
What are you actually trying to change?

Ya I forgot about keyboard pausing.

I was trying to get rid of the annoying confirmation dialogue each time I exit LinuxCNC.

Is there another option for this?

I guess I broke the behaviour a while back.
What you did was the right thing.

I have just fixed it - next update you can try it again.

I'd just like to say how much I appreciate all of your perseverance.

With all of you'r effort & willingness to help I can see one day QTDragon will be to go to interface for LinuxCNC.

Thanks again.

Here is an update that allows using the pause key too.

The external pin  only can pause - would toggling on each true state be better or a separate external pin to unpause?

I was thinking maybe it would be better to have the pause button do regular motion pausing/unpausing and have the spindle pause button do motion pause, spindle pause and spindle lift.
That way you could do either - it may be more useful/intuitive for other people and if so could be incorporated into qtdragon as standard.

interesting request anyway - hope it improves your experience with linuxcnc!

Thank you for the kind words - QtDragon in linuxcnc is the combination of many people's work.
Jim the original creator has an even nicer looking version that i hope to soonish get started into master branch.

This now also works from the keyboard.
"..would be better to have the pause button do regular motion pausing/unpausing and have the spindle pause button do motion pause, spindle pause and spindle lift."

I think it's a very good idea, integrate with qtdragon and you could make this behavior an optional choice.

HI there

I have also tested it & it works as expected.

One small thing... If I hit the stop button the script runs ( to return to the home switches in my case) but if I hit ESC to abort it does not.

I don't know if this uses the same mechanism as pause but I thought I'd point it out.

Thanks

For the benefit of those who come after & myself in 6 months time her is a summary of things so far...

1) In your INI file add to the following sections

[DISPLAY]
USER_COMMAND_FILE = CONFIGFOLDER/pause_pin.py

[AXIS_Z]
OFFSET_AV_RATIO  = 0.2

2) In your custom_postgui.hal add

#Actually stop spindle whwen spinle pause is pressed
    net spindle-stop         qtdragon.spindle-inhibit             spindle.0.inhibit

# Set up Z axis external offsets
    net eoffset_clear       qtdragon.eoffset-clear                => axis.z.eoffset-clear
    net eoffset_count      qtdragon.eoffset-spindle-count   => axis.z.eoffset-counts
    net eoffset                 qtdragon.eoffset-value               <= axis.z.eoffset
    
setp     axis.z.eoffset-enable     1
setp     axis.z.eoffset-scale       1.0

# uncomment for dragon_hd
#    net limited                qtdragon.led-limits-tripped          <= motion.eoffset-limited

3) Download pause_pin_2023-09-18.py and save to your config folder as pause_pin.py
Set the "Spindle Raise" in the setting tab to a sensible value.

4) In qtdragon.pref 
shutdown_check = True
Must remain as True in order to save "Spindle Raise" value.

If there's anything I have missed please let me know.

Hello,
I can't seem to find the file pause_pin.py. Does the path have to be exactly "USER_COMMAND_FILE = CONFIGFOLDER/pause_pin.py" and does that mean my machine folder? Or where does the file have to be located?

Hello,
I'm using the file pause_pin_2023-09-18.py and I'm getting an error message.
I started LinuxCNC in the terminal with "linuxcnc -v My-Machine.ini" and I get this message:

User command file for pause pin found

[QTvcp.QTVCP.QT_MAKEGUI][ERROR]  No module named 'qtdragon_handler' (qt_makegui.py:361)
Traceback (most recent call last):

  File "pause_pin.py", line 5, in <module>
    import qtdragon_handler as SELF
ModuleNotFoundError: No module named 'qtdragon_handler'

How can I fix the error?
