Filament run-out sensor

What is the problem?

Octoprint do not stop printing when filament runs out (factory run-out sensor of Ender 5 Plus)

What did you already try to solve it?


Have you tried running in safe mode?


Did running in safe mode solve the problem?


Systeminfo Bundle

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

Additional information about your setup

OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible

Ender 5 Plus, recently purchased from Amazon

FYI: The systeminfo bundle is not this system info list, it's the zipped file you can find at the and of the systeminfo list.

Also it could be (very likely) that the printer firmware does not pass on the filament run out event to the host software via USB.

Your firmware needs to tell OctoPrint to pause on filament runout. Check this FAQ entry:

You'll probably have to update/change your firmware.

Thank you very much foosel, I cannot find "#define HOST_ACTION_COMMANDS" in Configuration_adv.h. Thinking I'll need to upgrade the firmware at one point... My Ender 5 Plus is running firmware version 1.70.2...

Got it, first time submitting a comment here... Here is the bundle... (34.0 KB)

It is there:
