Talk about rabbit holes!!!
It’s definitely not plug and play. You want a perfectly level, rock solid vibration-proof surface in a place free from drafts and hopefully with a pretty steady ambient temperature, to start with. (I had all that worked out perfectly, and then my GF arrived and booted the 3D printer out of the space!)
There are some really cool filaments that look like wood, metal, etc. They are awesome but can really make you tear your hair out (the wood especially) by hopelessly clogging your nozzle just when you’re thinking the print is going to turn out amazing.
I’ve had mine for 3 years and still feel hopelessly stupid when I use it, and totally amazed whenever I manage to get something to turn out right.
All that said, the best advice I ever got was this:
Nail the first layer.
It gets tedious and boring, but if you get the first layer down (even all the way across, not too squished onto the bed, but not coming unstuck anywhere, measuring the correct thickness, etc.) you’re 'way ahead of the game.
Good luck, and have fun!
