+pause_on_runout: True
+#   When set to True, a PAUSE will execute immediately after a runout
+#   is detected. Note that if pause_on_runout is False and the
+#   runout_gcode is omitted then runout detection is disabled. Default
+#   is True.
+runout_gcode:
+#   A list of G-Code commands to execute after a filament runout is
+#   detected. See docs/Command_Templates.md for G-Code format. If
+#   pause_on_runout is set to True this G-Code will run after the
+#   PAUSE is complete. The default is not to run any G-Code commands.

+#event_delay: 3.0
+#   The minimum amount of time in seconds to delay between events.

+#   ignored. The default is 3 seconds.
+#pause_delay: 0.5
+#   The amount of time to delay, in seconds, between the pause command
+#   dispatch and execution of the runout_gcode. It may be useful to
+#   increase this delay if OctoPrint exhibits strange pause behavior.
+#   Default is 0.5 seconds.
+#debounce_delay: 1
+#   A period of time in seconds to debounce events prior to running the
+#   switch gcode. The switch must he held in a single state for at least
+#   this long to activate. If the switch is toggled on/off during this delay,
+#   the event is ignored. Default is 0.
