Don't know anything about it Mr Musk,

but seeing your images,

most likely if the assembly machines

were smaller, as in, much smaller,

 

it would be more precise relative to the aims it has on the board.

 

It kinda feels like the unit of measurement,

despite, i'm sure is being told precise,

 

is a hit or miss, when there is so much movement

at that giant scale (machine being too big).

 

Don't know. My imagination.
