To print the whole globe will take my printer 36 hours, so I went to campus and left there printing, because my printer with that filament rarely caused any trouble. But! When I casually checked my raspberry Pi webcam to see the progress, I saw this disaster. the filament was running everywhere and bandaging the print. I stopped my printer immediately through my phone  and ran back home to see what happened.

It turns out the filament feed tube was loose and fell out, resulting in filaments was not able to be fed to the printer nozzle. 

After all the tinkering, the printer was fixed and gcode got edited for the printer to continue printing on that specific layer. 

Shxt happens again. Since it was my first time having this kind of issue, I forgot to add M140 to the gcode for it not to home all the axis before continue printing, so while it was homing, the print got knocked off the print bed and lost all the relative coordinates.

I was forced to print the other half separately and glue them together.
