Dimensional accuracy doesn't necessarily mean detail. What are your expectations? You should be able to get fairly crisp and dimensionally accurate prints, but there's a ceiling. With FDM you're ultimately running what could be considered a CNC hot glue gun so absolute accuracy won't ever be as good as a resin or SLS printer.

Do your parts look good, but their dimensions are off? If yes, you probably need to scale your parts to accomodate for shrinkage. That's what the Voron team did and their parts fit together really nicely with non-printed parts when printed on a decently tuned printer. Their threaded test prints are a pretty good indication of how well dialed in your printer is.

Some of this also comes down to temp and material, so if you had the perfect interface and changed material you might need to iterate a few times. There are also the design quirks that you learn as you go, especially for things like small holes in parts often being smaller printed than designed. Print a hole gauge set, with a series of holes ranging in size, and use the one whose printed - not designed - dimensions are the one you want.
