Used it again today, same beans, same tech, but I closed the burrs by 5 clicks. No more boulders, same-ish fines, still kind of meh taste? I might brew these beans with the LIDO tomorrow to see if it's just the NEWB roasting the beans and not the grinder.
My impression so far stands, it grinds pretty fast and is easy to adjust, providing you know how many clicks you like. I estimate I am about 20 to 40 clicks away from closed. Just a guess.
