So, I've got some more footage and pictures to show about the printer.

First:

As I said, the filament would extrude without trouble when I load it.

Above is a video of the printer extruding PLA when I ran the load filament script.

The pictures above are of the extruded filament.

Second:

I decided to try a print so I could take photos of the jammed extruder from the inside.
Note: The first several layers printed without any trouble and very cleanly. Also, it seems that the printer jams when printing the infill, not the perimeters.

Above are photos of the inside of the extruder after jamming.

Here is the end of the filament after I ran the unload script and removed it.

Above is a photo of the incomplete print still on the bed.

Again, here's a link to a ZIP containing all the pictures in higher resolution: https://www.dropbox.com/s/aofvk4gja2...t%202.zip?dl=0
