Actually turning the spindle off, not just temporarily inhibiting it.

With lut5, I've managed to set spindle.0.inhibit based on a few inputs (collect-locked, pressure-ok, temp-ok). This works fine, and the spindle is inhibited.

I can, for example, eject the tool holder, issue M3, and the spindle won't start. But if I put a tool holder in, the spindle starts up because the M3 is still in effect.

What I need is for the M3 to be canceled if the spindle-inhibit asserts. How do I do that?

use the halui spindle-off

It would be helpful to have more context.
What are you using to do this tool change ?
Is this a manual mode, is it a remap toolchange?
During toolchanges in auto mode the spindle is usually turned off automatically.

This is just a safety interlock, but I think I actually need to stop program execution as well as the spindle. I'll give halui a try.a

This is just general information;
to get good and direct answers, it really helps to give as much detail as possible.
and to answer any questions asked as best you can.

You started with asking about turning the spindle off, now you are talking about aborting the program.
Tell us in detail what you are try to achieve.
A safety interlock for what action?

For instance an interlock on the door might stock the spindle and stop the feeding, but not abort the program or you may prefer to abort the program (which would stop the spindle automatically if the spindle is computer controlled like yours).

As I said, safety interlock.

There's a million moving pieces as I put this machine together. I sometimes get bogged down in a detail. Nevertheless, this is how I learn so an answer to my question as asked is very helpful to me, as is an answer to the larger question of how to achieve what I'm trying to achieve.

What am I trying to achieve? Building a router table.

using HAL:
halui.abort

using python:
import linuxcnc
c = linuxcnc.command()
c.abort()
