Yeah, I guess I got to the point where I had an entire workstation dedicated to an old POS computer that didn't meet my design requirements on any other level otherwise, so I just couldn't justify having it take up so much space.

Recently I went on AliExpress and purchased these:

(3x) http://www.aliexpress.com/item/A931A...093264436.html

With a typical Parallel Port operated CNC controller, the power that goes to it also drives the steppers, but this guy was sending signals perfectly, but just didn't have enough juice to drive anything, so that's why I need the extra stepper drivers. They're still on their way, so I hope everything works out the way I'm intending. But yeah, installed the software, and everything seems to be working just fine so far.
