[Emc-users] Controling Hardware ?

[mike a <mik...@ya...>]

I am new to the EMC list, i have a background in
electronics technology and worked in the IT field for
several years networking. I have an asian bridgeport
style mill I would like to fit for cnc use. 
From what I gather I would need about 600in/oz
steppers to drive the table and knee.
My questions were regarding the various hardware to
drive them, I have seen pci cards and drive amplifying
boxes that are external as well as breakout boards.But
no real info on the differences.
Power supply external would be no problem as I could
scratch build to total current and voltage specs. 
What I am wondering is what is required minimum for
three axis stepper control using serial or parallel
port on the pc.
I had a bit of confusion about how all the different
controler cards of the pci variety worked in how they
interface with the motors etc.. 
What are the advantages and disadvantages of the
different methods? I'd prefer to stay away from
servos.
.
Also please include any links to drive products that
go b/t parallel/serial port and stepper motors that
are known to work well with EMC.
Any schematics for the build it yourselfers?
 Thanks for replys
Mike
