A simple commercial 3D printer in the $4,000+ range, which has a smaller build volume than you have, will work right out of the box, but that is a lot of money for most hobbyists, not to mention the maintenance agreements. If this is for business, then you might need to reconsider your options.
Like anything new, there is a lot to learn. 3D printing in the consumer space, has quite a way to go before it’s just plug 'N play. You’ll need to learn a lot about how the different parts work and react with one another, while also learning how the materials react. I read as much as I can about 3D printers, and the materials available, while also watching a TON of videos. As an engineer, I specifically look for things that can go wrong. If you put yourself into an engineering mindset, that is where you want to be.
Everyone learns at their own pace, and you will get there, so hang in there. If you get frustrated, try slowing down some, and maybe even taking a break to do something else that you are already good at. The most important thing is to enjoy the experience as much as you can.
