Update: Yep alignment DOES matter. Helps with a more consistent grind, however even on a not perfectly aligned grinder you can get great results, but it does limit it's maximum potential in a way.
A well Aligned DF64 with SSP Espresso burrs, vs a not perfectly aligned DF64 with Unimodal burrs, the Unimodals still did a better job (cleaner, less bitter, due to less fines) as expected for brew coffee where that burr excels.
