Huh?
What was that drivel???

You OBVIOUSLY are not familiar with why machines are used in say ANYTHING!!

Once a machine has been calibrated, setup, configured and shut down it WILL keep said settings.

Machines/robots are used precisely for reasons previously stated…repeatability of said process, repeatability of results, especially when used for optical scanning operations.

But of course your degree in Engineering…oh wait, you don’t have a degree in Engineering???
