options for combining probe, home and/or torch breakaway?

Thanks for the followup Andy.   Greatly appreciated.

What you said makes total sense and I started out trying to do something like what you gave.  I got several errors like "Pin 'plasmac.breakaway' was already linked to signal 'plasma:breakaway-switch-out'" and more like that.  I'm probably running up against some newbie ignorance here.     I think, not sure, that something in the setup done by pncconf already created connections like that?  

I suspect that my ladder is probably a hack and just creating a new unused signal to get around what I don't quite fully understand.   I'm also probably getting signals and pins mixed up.

So I'll beat my head against this a bit more.  I want to learn how to this right as I'm sure I'll be doing more customizations down the road and some a good bit more complex.   If I get over this simple attempt, those will go much better.

Just for reference, I believe the actual syntax I would use with my h/w would look like this if I emulated the example you gave:

I'm going through my config files today to see where those signals/pins are already linked, try to unlink them and then try this approach and see what happens.   I backed up my config first.  

Update: I quickly got into trouble. :/

By trying to unlink things to fix those errors I found they're tied to more things like debouncing physical inputs signals that are then tied to stuff in the GUI and possibly other things I'm not sure about. I quickly got lost.

I'm sure it's doable but rather than try to sort that all out I'll stick with the ladder approach. I realize it's possibly an unnecessary layer of abstraction but that's working for me at the moment.

I still have a torch holder & the actual breakaway mount to build. Time to get on that.

FWIW I run my table without a separate wire for breakaway. Mine is mechanically designed so that only one switch is required. You could use a n/c float switch and a n/c breakaway switch wired in series to the float switch input. The float switch input will act as both/either depending on what state the machine is in.
