 So you got a brand new printer and a new roll of filament, but you don't know how to insert it. Well, I can tell you many people have been doing it all wrong and I'm going to show you how to do it right. Before we do that, we need to talk about the correct way to hold a spool. You always want to have the filament in your fingers like this so you don't let it go or in one of the slots in the spool. You never want this to let go and spring all over because it will get wrapped up and you will get stuck. Now you don't just want to make a straight up and down cut because that'll be super hard to go through your extruder gears. What you want to do is take your side cutters and go in a very steep angle so it's angled a lot like this. This will allow it to slide into your extruder right through those gears and into your printer. Squeeze the arm of your extruder, push the filament in and you're ready to print.
