While your extruder is still hot, pull the filament completely out of the filament tube. Turn your Extruder Heater OFF (shown by the pink box in the first image).
Always verify the heater is off when finished. Leaving the extruder heated in the manual control window without extruding for extended periods will over-bake the plastic and lead to nozzle clogging.
Cut off the melted end of your filament and straighten the first 3" again.
Insert the Filament Tube into the Tube Quick-Release Fitting, shown by the green arrow in the second image. Pull up on the Filament Tube to make sure it's locked in place. If it becomes unlocked during a print, the printer will not be able to extrude.
Whenever you go to remove this tube, push both the tube and the Quick-Release Fitting downward. Then tightly hold the top of the fitting all the way down and pull upward on the tube.
As shown by the blue arrow in the third image, insert the filament upwards through the Filament Drive and on through the Filament Tube. Push it the entire way into the 3D Printing Head, until you cannot push it further. This is where the straightness of the initial filament really matters.
Double-check that your spool of filament is able to rotate freely, so that filament can unravel smoothly as the Filament Drive pulls it.
Reheat the extruder to 210 C and use the manual control buttons to extrude 100mm of filament so that you are sure the filament has made it all the way to the nozzle. Turn the Extruder Heater OFF once finished.
