What is the problem?

How can I go about using the stock filament runout sensor with octoprint on the ender s1 pro that has stock firmware on it?

What did you already try to solve it?

Research on the problem led to very scattered results. Possibly no solution.

Have you tried running in safe mode?

I don't think this is necessary

Did running in safe mode solve the problem?

See above.

You can download this in OctoPrint's System Information dialog ... no bundle, no support!)

The firmware version is in the bundle and can be determined by using the OctoPrint Terminal tab and sending an M115 to the printer (the M115 output is also in the bundle).

The M115 will also provide the capabilities of the printer and for OctoPrint to use the filament runout sensor, HOST_ACTION_COMMANDS needs to be enabled in the firmware. You might also need PROMPT_SUPPORT.

If you search this forum for "Ender 3 HOST_ACTION_COMMANDS" you will find many topics. Bottom line is you will need to either find firmware from somewhere or compile your own if you wish to have OctoPrint handle filament runout.
