I'm getting this feedback in my logs:

Do you have halui.pause or resume pin connected somewhere?
from the docs:

If using the Spindle lift option, HALUI can not be used to pause/resume the program. There is a pin, QtDragon.external-pause available to pause/resume from an external source. You must also enable external offsets. In the setting tab check use external offsets

also for qtdragon_hd line 41 should be un commented

The halui.pause nad halui.resume are coming from the xhc-whb04b-6.hal file.

I'm not sure how to change those entries.

Could try this change and remove the resume (line 21).
I might need to make a separate resume pin for you for this case.
or add some logic to convert the pause/resume pins to one pin that is true for pause and false for resume.

What about the other question that I had? Not sure if you noticed that?

"Do I need both lines 41 and 46?"

Please remind (show) me of the pause pin code you are using.

So from memory I made that pause_pin.py modification because qtdragon_hd had no external way to pause the program.

In master at least there now is an external pin for pausing, so you might not need that part.
I see you have a bit for running a oword sub on abort - you'll still need that.

So please confirm you are using current master.
If so you will probably see two external pins qtdragon.external-pause and qtdragon.external-pause-2 is that true?
if so you should not need line 46.
finally you could try commenting out the halui pause/resume lines temparaily.

Confirmed that I am using the most current master of linuxcnc.

I don't see the pause_pin.py anywhere other than when you posted on a previous thread .

qtdragon.external-pause-2  does not exist.

What I meant is, in that latest master code the external-pause pin is built in to qtdragon/hd so you don't need the pause_pin.py file to add the pin.
You would still need the part that calls an oword program on abort.

Can you run linuxcnc in a terminal, with DISPLAY = qtvcp -d qtdragon_hd in the INI and post it?
