I think this actually helps ‘limit’ your scope significantly. As most of the options out there are only really rated for the hobby market and max out at our current motor spec (Nema 23, 2.8amp, 178). Anything more than this, and you’d be exceeding most controllers with “built in drivers”.
If you’re already looking at more medium grade, than ignore the above. I’ve posted here a few options as well.
Because of this, I’d highly recommend the Gecko G540, as a great all-in-one 4-axis driver package. I run this on other machines with much larger motors/demands. You’d still need a controller to drive these, but your options are open there.
