Start PathPilot without a Mesa card connected

Though I suspect they will not let the system out of EStop until all is powered
and working.

Why would you want to launch LinuxCNC when it cannot actually run?

You are correct, can’t do much until power is on and you “reset”.

Honestly, the biggest reason is that I forget to turn the cabinet on and LCNC yells at me :laugh:

Then I have to repeat the process of starting after I remember to turn on the cabinet. Otherwise, probably not much reason.

Its probably possible to launch LinuxCNC by deferring the parts of hal that access
the hardware to a hal section that's loaded later.

You could also have a script that determines if the hardware is available and puts
up a "Waiting for Control power" notifier until the hardware is detected

I’m not sure how to execute that, but it would be awesome.

Heres the basic idea:

Someone with python or tcl smarts could do a nice graphic version

Oh I’m picking up what you’re putting down now. Gives me a few ideas and a starting point. Thanks!

If you have a PCI driven 7i76 is there a way anyone has used to achieve a similar approach to this ping?  Maybe some halcmds that if fail can return a fail value that bash could use?
