For the sake of a response, I believe the problem is resolved. I was actually able to cut out the logic converters, and the 3.3v from my Smoothieboard work on the stepper drivers. I'm using the drivers to push 2.5 amps to my steppers. Why? Because freedom. Also, it was recommended by the supplier when I querried. Also, my 3D printer will have cnc capability, so I want the strength.
The main solution however seems to have been reducing the microstepping on the drivers. Doesn't make sense to me though because I have to run at 1/16th micro stepping while the smoothie should be capable of higher. Hell, maybe it just boils down to that I got the stepper drivers from China and they aren't capable of higher levels of microstepping despite the labling. It's nice to have them working, but still dissatisfied to not know the exact reason...
