In article , Harold & Susan Vordos says...

... it's highly unlikely new guys in the hobby will take the
time and gain enough experience to work with the screws. It takes years of
experience to work that way and do it without making scrap.

I think that most of the folks here *do* work with the
lead screws, because that's all they have. The machine
with the used lead screws isn't fast (doesn't have to
be for the hobby metalworker) and it's certainly less
accurate than one with new leadscrews, aside from
one with a dro.

But typically it's what we have, and so we use it until
the money arrives for new lead screws or a dro setup.
Personally I would rather have the first, under most
conditions.

Most folks in a *production* environment would not have
the slightest clue about how to run a machine with manual
leadscrews, most shops like that are all NC and those
use ball screws. The carriage simply *is* where the
number on the screen says it is. If they were given
a manual machine, the first thing the new crop of
machine operators would say is "Hey. This thing's
broken!"
