There is some slight adjustment by the hole sizing on everything - how much can the software make up for sub mm "corrections"
Maybe overthinking it - but also don't want to end up with something not accurate after all the effort.
As I haven't owned a CNC machine before I don't know what accuracy I'd like, but for example if I could produce something like the Aztec calendar I'd be happy..
Don't stress over it and it's perfectly possible to build an accurate machine that will easily cut the Aztec calendar by using hand tools, most of the builds on this forum are built solely using hand tools or a large percentage.

Accuracy comes from the setting up and alignment etc. Remember Adjustment, Adjustment Adjustment so slightly oversize holes can help here.
