Hi, all. I've had my Preciso for about a week now and am loving it. After reading pretty much everything I could dig up on the grinder here and elsewhere, I was surprised to find that the micro adjust lever doesn't appear to be stepped on mine, i.e. it doesn't click or encounter extra resistance at all when going from A to B, from B to C, etc., on up to K. I'm not noticing any drift while grinding, so I don't think there's a problem, per se (though I do hear clicks when the micro lever is moved in the YouTube video reviews of other Preciso units by Seattle Coffee Gear and Whole Latte Love). It's just interesting to me that my micro adjustment system seems to be effectively stepless. Should I worry or celebrate? Anyone else going through click withdrawal with the Preciso? ;)
On mine the detents or clicks appear to be the result of the adjustment button interacting with the small radial grooves on the visible A to K scale. In other words, if you sort of push down on that adjustment button as you move it left or right, you should clearly feel the detents. If you lift UP on the adjustment button as you move it, not so much. But it does seem to be stepless, in the sense that you can position it in between detents.
Thanks for the reply. If I push down on the lever as you described I can feel maybe one or two of the detents toward the coarse end of the micro adjustment range, true, but it's really a very subtle thing. And there are still no audible clicks. Stepless, indeed.
The mico arm moves through a full endless 360° circle over & over, but of course is limited to the designed upper frame cutout in the metal & the ABS plastic indexing piece.
With a tiny amount of flex of the indexing arm, sometimes the adjusting tab/button on the top of that arm can slip a tad & result in the less than secure clicks at the detents that you're feeling. This can be fixed easily.
Move the slider off center left or right 2 to 3 clicks (to move the bottom part of the arm away from interfering with the top area of the coffee discharge chute).
Take a very small screwdriver or something suitable to slide up under the bottom curved area of the arm & lift/hold up slightly.
Push down firmly on the adjusting tab/button to snap/click it into its locking position firmly.
I tried reseating the button on the micro arm the way you described. It seemed to make a small difference. Then I happened to be grinding for an espresso and noticed that over the course of the grind the micro arm drifted slightly from D toward E (of course, I was paying closer attention than I usually would!). A Baratza rep. thinks the button's the issue, so he's sending me 3 spares to play with. Works for me. We'll see if one of them makes a difference. Some of this is undoubtedly just fussiness on my part since it's a new machine.
