That may well be true, but for a beginner (he said he was new) that
is just learning the termonology, I would assume he has some
preconceived notions that will be disabused once he learns about what
is fast and easy and cheap.

Our friend Cranky (crankorgan) had stated more than a few times that
something over 90% of the people who spin motors never build anything
past that point.

His point being that if you spin motors right away, you never build
the machine.

Whereas if you build the machine, the last thing you do is spin
motors. so, the last thing you do is spin motors. it's just were in
the process you do that.

If someone thinks they are going to write a CNC controller for a
microcontroller, they may take months, then spin motors and realize
they only took a baby step and there is lots of work ahead.

I was trying to point out that the poster does not need software
until the machine is nearly built. And then if he is writing for
serial input, there are very few options. And.. if I am not
mistaken, Fred, you are the only one to offer what he asked for. a
serial option.
