Ran large print overnight.
Filament ran out half way.
Print continued.
How to resume print from any given layer ?
Also how to test if the sensor working at all ?
Not possible on an existing print. You can reprint the remaining layers and glue the parts togther.
First I would check the sensor and see if something is jamming it.
To test it, start a print from an external spool but without any filament loaded. The print should ask you to load filament, Once you load it, it should continue with the print.
You can test the runout sensor by cutting the filament while printing and see if it pauses the print when the filament clears the sensor.
Nothing is jamming.
Latch inside sensor moves freely.
I tried to extrude manually using STUDIO and it keeps extruding even when there is no filament.
I tried to start a print without filament, print started.
Maybe this is because of my GCODE ?

Switch back to the default start gcode and see if that fixes the issue.
Manually extruding doesn’t use in the filament sensor.
It worked. But i need to know why
