Amazing! But, WOW, I'd hate to see those lead screws after a month of
that. I wonder what the maintenance schedule is on an industrial CNC

Its my understanding that for machines like that they use precision balls
screws with preloaded nuts because the service life is very predictable.
Does seem like over kill to make perforated metal sheets though. LOL. I
like it.
