What exactly is the difference in LinuxCNC with the red ESTOP button and the
orange Machine ENABLE button?
This is a holdover from the original EMC days when it only
handled analog servo systems. F1 would take you from E-stop
to Machine-OFF, which enabled the servos, but did not give
them any velocity command. F2 would go from Machine-off
to machine-On, which enabled the PID servo positioning
loop. This allowed you to check the servo drift, but you
didn't want to stay in Machine-Off for very long as the
machine would drift position.
I don't know of any other system that works this way.
