what do you think about this combination ...

drivers
http://www.pminmo.com/l297-8/l297-8.htm
interface
http://pminmo.com/3axisopto/3axisopto.htm

or is the better to go for those drivers and interface pminmo has in his shop
L297-8 board and 4 axis interface ?

i don't need 4axis on current machine, so it's not a problem.

1x279805

is second one better ? the problem is i couldn't find copper layout for it ...
or the first one should work just as good ?

and btw, what is purpose of usb connector on that interface board you mention ?

[pminmo]

One is arranged for the DIY'er to make via toner transfer, the other takes advantage of the fine trace capability that at commercial pcb house can do.

[turpija]

aha, that's fine.

and what about usb connector on interface board ?

[pminmo]
