Finally found out why I wasn't able to tune the fence and miter gauge of the table saw down to the last percent of accuracy. Turns out the blade itself wasn't parallel to the miter slots, as it's supposed to be when coming from the factory.
So I RTFM and found some screws to adjust it, which I had no idea existed at all.
Definitely not a thing you hear a lot about in beginner learning material, but adjusting your machines properly seems to be quite an important skill and semi-regular task in #woodworking.

Been there, done that 😄
There are many good videos around.
If you can understand Italian, follow this woodworking channel by Stefano il Falegname:

For Californian English, instead, I suggest Steve Ramsey:

For both start from the oldest videos, there are hidden gems.
