.04 would be way too fine for any espresso on my Hiku. .07-.08 seems to work well for my pump machine. A little coarser for the spring lever.

Yes the inner burr is tighten sufficiently, too tight and the burr rub would get worst at earlier settings.

Grind settings at 0.7 is too coarse (visually) for espresso. my V60 settings is around 1.2-1.4.

This grinder right out of the box was giving me problems, the three lower screws were tighten too tightly, causing the adjustment ring to be unable to move. Took me a while to figure out how to resolve it as it did not come with any instructions. An expensive KS lesson learnt for me.

It certainly sounds like you got a lemon. Have you asked Kanso to cover the return shipping cost?

I tried the Hiku with my Pavoni. There I had great results! So I might keep my Hiku as espresso grinder. Just cannot get it to work with my v60, not coarse enough and really lack flavor and get higher body results. Time to open up my Hiku to inspect the build.

Any updates of adjusting your Kinus? Anyone get their's straightened out?

Based on my own experience with Hiku and reading reviews to know if I had a defective unit, I don't believe I had one. I believe Hiku is not a grinder well suited for pourover range. Not a homogeneous enough grind and at pourover grind sizes little adjustments are simply not possible.

Not homogeneous for a grinder points to decentering, and this can be easily diagnosed.

I didn't feel the need for little adjustments for any of the brew methods, is not critical as for espresso.
While for espresso the range on my Kinu/Pavoni is limited between 1.2-1.3, for brew I feel free to swing between 2.0 and 3.0, without worry will miss a good extraction.

The original burrs do seem to be optimized for espresso & they do a great job in that range. Not too long ago they posted a photo on Instagram of a new set of "brew" range burrs they plan to offer. No idea when they will be available.
