The grinder is ready for prime time. The manual is not. I finally got mine programed and it's working like a dream.
Even the menu system is a bit quirky. For example, when you get to this edit screen, the blank upper right tile accesses the advanced menu. Nowhere does it indicate that!
And pressing the "900RPM" button gets you into the RPM adjustment menu. Pushing and holding the same button gets you into a deeper level.
So it seems everything has been thought out functionally, just not programming-wise.
I would anticipate a firmware upgrade at some point.
