If you want to add more drivers for say the B and C motors, get another 2 axis board( or (2) 3 axis boards). If it needs a parallel port too, you can add a second parallel port PCI card. i got this one
at Dell a while back just in case I need it. I still have my old Stepperworld 3 axis driver.
Wanted to have the parts ready in case I needed a Slave for the Z axis or to play with a 5th Axis.
There are cheaper parallel cards out there than Dell for sure.
crap, here's one I just found thru
pricewatch.com for
$9.
My xylotex is a bipolar driver but the stepperworld is a unipolar (why i yanked it)
I would make sure the slave is using the same board as the master.
