I have PLA dialed in, ABS kinda dialed in but really need an enclosure to get better adhesion. Just received some PETG to try and realized I am not sure on what is the recommended way to change filaments. I don't want to have to tear this hot end down to fix a clog.

I have heated up the hot end disengaged the bearing and just yanked it out. Should I push some through first? Retract a little first? Does it even matter?

Thanks.
