the Sri demo shows 2d motion. pcbs make it pretty straightforward to have an X and a Y array, but for some reason it doesn't seem to me like you can just easily drive both axes independently. could you really tune a 'step' to be on an arbitrary slope?
I'd say that depends more on how much you are willing expend on hardware to drive it. You could slice your coils into tiny segments (essentially: just the tops) and then use the back of the PCB to drive them. They'd be magnetic pixels. Maxels?
Interesting challenge, can you 'microstep' along two axis at once without losing sync? That would be neat. I think I've worked out a way to rotate them as well!

good idea - but that's alot* of drivers
You might be able to do something here along the lines of row and column addressing of DRAM.
If you move X,Y separately but with a small enough step, it would be virtually indistinguishable from moving along the slope.

I would imagine so; it should be the same problem as helical interpolation, but confined to two axes. https://infosys.beckhoff.com/english.php?content=../content/...
With 4 layers, it would be a trivial extension to drive a y axis
