Pella Darn web site! Looks like a plasterer turned web designer -- missed mor'n a few spots on the ceiling near the corners.
The breakout board is passive which can be both a good and bad thing. Bad because you have to look to the parport to put out enough voltage to signal the drives. Good because you can wire it up most any way that you like so EMC's sigs are all available. Looks like the logic signals of the microstepping driver requires a +5 volt signal. This will be an issue with on-mobo parports but can be handled with a PCI parport card. H8-MD81-336 is sort of an unknown on the site. 'There is no product that matches the search criteria.' They give you three of these and the number inside () comes close to that of a NEMA 34 motor listed. Plenty of torque there for a modest mill. They draw 4.2 amps with a >5 ohm resistance. The motor power supply handles "68V DC at 5A." Looks like they intend you to parallel the outputs of the two power supplies or put two drivers on one and one on the other. Since they call them a "non regulated switch mode power supply" I'd be just a bit nervous of paralleling them but others would know the details of that much better than I do. Trying to run two motors from one drive seems like it would overload the bugger just a bit. So worst case IMO I'd add a parport card to my PC or an active breakout card and I'd purchase a third power supply.
