Step & Direction 3 axis board plan

Dear lister!

You guys and ladies (any?) are doing a great job and since on the list I
have learned a lot from you!
I am in an early stage of building a tiny milling machine to use it for fun
(next to my printer on my desktop ;-). I have found quite some amount of
freeware and shareware on the web and have found out that there are several
approaches to motion control of three stepper motors. I se that the most
common one is step&direction approach using only two pins to control one
motor. I would like to build a motion control card like that, but I can not
find any plans on the web for it. Any of you listers have them and willing
to share them with others? I would be immensely happy to se one published.

With best regards, Matjaz
