I wired my z steppers in series and was happy with the result! I think that's in the manual....

Honestly it's more the cable i'm worried about than the driver.
Alright after alot of stupid crap I finally got it working.

And alot of fiddling with the print settings. Started out with the head deciding to move up about 5mm before starting each print, but changing the initialization G code a bit stopped that. I was then massively over-extruding, then under extruding. And now i'm sort of in the ballpark with it.

(usual disclaimers. looks alot worse in the photos. still not ideal)
20x20x10mm cube. I've yet to measure it. I'll grab the calipers next time I go downstairs. I think the slight wobbling is from not having a cooling fan, and the fill layers pulling the walls in a bit. Maybe getting the extrusion setting just right would further reduce that too.
I was very fortunate to have just recently met a guy online who's into this stuff. He was able to guide me through alot of the problems I was having, and I wouldn't have figured most of them out on my own. A big one was needing to install the smoothieware drivers and then, through the Windows device manager, install the drivers again (by looking for them on the list of installed drivers) on the MKS SBASE board. So it'd show up as a COM port.
I'm running Marlin 2.0 on the board. It's still in development which made it a real chore to look information up, since fixed problems got broken again, and broken stuff gets fixed on a weekly basis. So most searches show up outdated information and fixes that no longer apply. Required installing a bunch of IDEs and editors to compile the firmware. Open source guys are weird.
Also they weren't kidding about PLA smelling great. It's like golden syrup.
Edit: Dimensions are about 19.9x19.9x10.1. That's better than I expected without any adjustments, but who knows how it holds over a larger piece. I'll do some more tests tomorrow, like the classic retraction pillars and just a big flat square or grid. I also need to measure skew on parts.
