I like Teaching Tech’s calibration guide.
And if you don’t mind me asking, where have you heard good things about volcano hotends, and what things specifically? Unfortunately it can be difficult to know who to trust nowadays as there’s a lot of affiliate links disguised as buying advice, paid “reviews”, and well meaning people who confidently repeat what they’ve heard without knowing anything about how true it is. Personally I’ve always thought of volcanoes as a niche item for increasing your print speed while potentially sacrificing some quality, but I’ve never used one myself so don’t trust me either :). Some people appear to be able to calibrate them properly but oozing seems like a very common problem. If you bought some random cheap hotend off amazon there’s definitely a risk that you got a dud, as you said.

The volcano was made for high volume prints and has a bigger melt zone. Ideally it’s best for bigger nozzles, high layer hights and faster printing.
If you want to print small and detail a normal e3d or other hotend gives you better control. For smaller characters you can use a standard hotend with a 0.3mm nozzle and switch on arachnid or similar in your slicer. That will give you pretty good results provided your cooling is good.
