John, I have an Ender 3 as well. They are great beginner machines. Easy to upgrade and print great. Sure it takes some fiddling to get it perfect, but I’ve seen what you do to an espresso machine, I have no doubt you can get it.
The teaching tech YouTube channel listed about is great. The other one that really helped me was Chep.
There’s some great YouTube videos out there too. Feel free to message me as well!
