im pretty sure that 6 is full stepping, and 7 is half stepping. my choice
to skip the optoisolators is because they cost money, and would take either
an order online or me hoping my hiney off that radioshack could be of any
use there and actually have one. I guess i could always salvage some from
old networking equipment, far as i know all those ports are optoisolated.
By the looks of it, i could have done without asking here. just read things
a few times and do some more googlin, and i think im gettin it figgered
out. but It'd still be nice to hear from someone running one of these modes
and how they're doing it.
