Hi guys. I have a peice of filament stuck in the very last part of the hot end. How could I remove this?

This is normal as this is where the filament is cut via the filament cutter.
If you must remove it. Heat up the the tip of the 1.5mm hex key with a lighter.
While the tip of the wrench is hot, quickly push it in the hotend, through the top end of the heatsink.
The hot wrench will go inside the filament, as shown in the image below. Then, wait for about 30 seconds for the hex wrench to get cold.
Finally pull on the hex key and the filament “plug” will often come right out. Alternatively the plug doesn’t come out you can heat the nozzle up with either the printer or a lighter and will will help remove the filament plug.
The full instruction from the wiki can be found here.

Much easier if you leave it attached and flush it out with a cold pull. Bambu has videos on this

I just had this happen on my E3D 0.6, and the hex key trick was the only solution that worked. It was old PETG and it also broke a piece off that lodged inside the extruder, and fooled the filament sensor. I trashed nearly a kg of PETG to avoid that happening again. I had dried the roll for hours too.
