This shouldn't be necesssary:
github.com/LinuxCNC/linuxcnc/blob/43ac97...motion/motion.c#L599
The pin defaults to true if not connected.
So it is probably a misconfigured HAL file. Can you attach the HAL file?

The program will run in G18. The status shows the interpreter status, and this runs ahead of the actual execution.
The reason that it goes back to G17 is the M30 at the end.
linuxcnc.org/docs/2.8/html/gcode/m-code.html#mcode:m2-m30
If you put % at the start and end and remove the M30 you will see the status remain in G17.

Adding % at both header & footer worked nicely.
We still have the feed holding though.

You could try adding a "sets" to set spindle-at-speed true, but it shouldn't be necessary and I am suspecting that the problem is something else.
Is it possible that the feed-override is set to 0% ?
Code:
net spindle-at-speed => spindle.0.at-speed
sets spindle-at-speed 1
Is it possible that the feed-override is set to 0% ?

feed over ride is 100%
I tried ' sets spindle-at-speed 1, '
No change.

I've created a quick lathe profile with stepconf and the issue is the same there as well.
