I'm doing my research phase now, which I usually do before any big purchase, so I have a good idea what I'm Getting myself into before I buy it.
The one thing that's kind of making me hesitant is all the different settings you have to change depending on filament type, nozzle size, if there's any layer separation or other defects from a print. Like how easy is that stuff to diagnose and fix?
Some printers are for the "I want to be able customize about everything" crowd. Some advocate for building or at least assembling your own to learn all about the mechanics and setup so you can diagnose and repair issues.
Make no mistake, this is FDM small scale manufacturing so there will be issues. If you get something like the Bambu, they've done A LOT to minimize the manual effort that can impact the quality of prints. BambuLabs printers self level the bed, can do flow calibration, and help detect defects just to name a few. Self leveling is something a few other manufacturers are now doing as well. Depending on where you search for models, most projects you download have print settings embedded in them tailored for your printer (e.g. MakerWorld.com for BambuLabs and Printables.com for Prusa.), but a lot of the settings and suggestions are also available within the slicer software. They'll provide warnings for things like using the wrong print plate with a particular filament, etc.
However just last week I ran into an issue with a brand new silk PLA filament that not only clogged the hot end, but locked up the extruder to the point I had to disassemble the entire print head as well as force out the gearing to remove the jammed filament. The good news is that companies like BambuLabs and Prusa have great online help to walk you through a lot of it, including how to do things like cold pulls to clean out any debris in the nozzle.
You'll have to be somewhat mechanically inclined and not afraid of working with somewhat delicate electronics regardless.
Also be aware that melting plastics is not without hazards, not just limited to toxic aerosols (especially if you're going to print with ABS or TPU), but many hard core print farms install fire suppression units (Google BlazeCut if interested) as destructive fires are uncommon but do happen.
It is a lot of fun and you're going to have a big learning curve but it's worth it if you enjoy making useful things. Just go into it knowing that failed prints happen, and you'll get frustrated with filament drying, measuring humidity, storage, etc. as well. With the right mindset it's an enjoyable endeavor.
You have probably seen unboxing videos of many of the available printers and BambuLabs, no joke, is pull-it-out-of-the-box, perform some very light assembly/remove packing material, power it on and print.
