The main thing I have learnt from starting 3D printing is that it is a hobby in its own right and you have to be a bit obsessive and tenacious (stubborn) to get a decent result. I seem to have slipped on every banana skin and fallen down every rabbit hole between taking the printer out of the box and getting a passable (although not really acceptable) result. There seem to be lots of places to share the fine tuning of 3D printers but I have not found much help getting over the initial blunders that I made when starting printing. Perhaps I am alone and everyone else got it right straight away...
