Revision to Connecting and configuring filament-out sensors

Tony

You can arrange for a simple switch to trigger user-defined actions:
 
The first step is to connect the switch to an unused endstop connector on the Duet WiFi2. Note that the Duet uses a separate connector for Z probes, and it has five endstop connectors (X, Y, Z, E0, and E1).

To make the firmware run a script when the filament runs out, use [[Gcode#Section_M581_Configure_external_trigger|M581]] to associate the endstop you chose with a "trigger". Trigger 0 is an emergency stop (probably not what you want), trigger 1 pauses the print (running pause.g), and otherwise trigger ''n'' runs the file trigger''n''.g., which you can write yourself.
