Switch mode from Auto to Man after abort was created by spumco
Starting new thread from here:

Topic: Aborted probing routine leaves LCNC in auto mode. Jogging, MDI, or other recovery actions not possible without the user manually switching modes.
@Lcette:
Yes, I think it's a chicken and egg problem.
@Aciera's response:
My idea - untested - is to do it through HAL using <on_abort.ngc>. I think Aciera's suggestion would be more graceful, especially if there's a way to point the python script to an INI section to connect the appropriate motion pin and other settings.
setp timedelay.N.on-delay 2
setp oneshot.N.width 1
net SIGNAL1 <= motion.digital-out-n
net SIGNAL1 => oneshot.N.in
net SIGNAL2 <= oneshot.N.out
net SIGNAL2 => timedelay.N.in
net SIGNAL3 <= timedelay.N.out
net SIGNAL3 => halui.mode.manual
I'll test out my HAL experiment this weekend and report back.

@Aciera's response:
It's not possible to switch to manual from gcode but you could set an analog output in gcode to indicate to a python component that you want to switch to manual mode when the gcode finishes or aborts (ie the interpreter switches to IDLE):
