NOTE: Removing the Bowden tube from the hotend on a V2 may be difficult. If you must remove the Bowden tube it may be easier to unscrew the connecter from the heat sink and cut the end of the Bowden tube as close as you can. Then remove the cut piece Bowden tube and push through connector.
Sorry about the portrait mode. Hopefully this will be a temporary video to be replaced with something a tad bit better. Hopefully.
The “set screw” or “grub screw” takes a 1.5mm or 1/16“ Allen wrench.
