I agree that if a machine was building copies of itself, the accuracy could be a problem, but I think that most of the parts would be within a specified tolerance, since in theory more parts would fall within a bell-curve than at the ends, no? Therefore we should get mostly usable parts.
I suppose we should have a separate machine to do QC, huh? ;-)

I'm not buying stock yet. Nobody has ever built a self-replicating
machine out of anything, let alone one made purely out of an RP

Anyway, isn't there a precision problem? If machine A can make parts
to tolerance .00x", and you build machine B out of parts made by A,
it's hard to see how the parts B makes can be better than 2 * .00x".
By the time you get to F, is it worth the trouble?
