I would suggest removing the nozzle, and clearing it if there’s a jam first, then seating the heat block to the break. Then the nozzle. Both the best break and the nozzle need to be hot as you’re doing the final tightening. I don’t know that the order really matters … it’s just how i do it. I do recommend being systematic about how you go through things. It’s helpful to have a process.

Systematic processes help you to not forget things, like forgetting to reconnect the BLtouch cable when doing stuff with the hot end. (Ooops.)

I’d also recommend keeping some of the more interesting failed prints as “art”. I may be weird but sometimes the spaghetti monsters look cool
