Hi I've had the Preciso for two months. Upgraded from the Rocky (for use on an equally new Rocket Cellini) and chose this after lots of research over a mini Mazz. Principally because the positive reviews and great customer service if it did indeed break down. Also it seemed the adjustability would result in fewer lost grounds during the dial-in process.
Alas, i am wasting many grinds now. I recalibrated to the near finest setting and have very little espresso play - Macro 0-2 and Micro B-C and only then get the good extraction. Totally unaceptable.
If you are familiar with the troubleshooting guide you can have a meaningful conversation with Baratza customer service tomorrow during hours. I have found them very helpful. If the calibration screw is at finest, then you have another problem and other sections of the guide may help.

Did it use to grind normal? Sounds like something wrong with the adjustment ring. Either way call/email baratza and they'll walk you through what to check or replace. I'm on Macro 8-10 for espresso, usually around 8, dependent on roast type, bean/blend, and dose.

I had similar issues with a 2012 Preciso (I've written about it here before, in fact just a few days ago) and needed to take apart the grinder and add shims under the lower burr (the shims are just metal washers). Baratza supplied them to me and have instructions on their website on how to do this. You may want to do this too, it allows you to grind finer. Call Baratza and see what they suggest...yours is under warranty so they might just do it for you. It's a bit of a pain in the butt to put the shims in but can also be fun if you enjoy taking apart machines.
Hi, thanks for the post. Yes it used to grind normal. I find it very challenging to be consistent. I typically am grinding Intelli or Apollo Espresso from Counter culture. Not too much variety but when dialing in now becomes very hard to replicate.
Already did the calibration but adjustment ring might not be sitting level.
Don't need shims, not when it used to grind fine/normal, that seems to only have effected your unit which is odd as heck as never heard of a shimmed Preciso, had to be one out of wack glitch with production. The grinder was designed with a huge espresso range.
Sounds like its the adjustment ring, had a similar issue once when I recalibrated it to fine. Put a new ring in and been perfect since. Never did really figure out what was wrong with the previous adjustment ring, but I described similar issue and they sent a replacement one out.
What were your settings before re-calibration? Were you at macro 02 then also? - it doesn't make sense if you recalibrated towards increased fineness and then had to grind finer.
My Preciso was purchased in mid 2012. Out of the box, I have always had to grind at either 02 or 03 macro for espresso. I finally decided to recalibrate this weekend. My hope was when I opened it up the calibration would be set at max course - and indeed that was the case. I recalibrated from course to 'normal' - and was expecting to be grinding around macro 10 - but in fact I dialed in at macro 07, which is an improvement.
Unfortunately, I have had the problem too. I believe the plastic starts to bend in the adjustment ring when using light roasted blends, and while I have not had Appollo it sounds to me like it's very light roasted. I busted two adjustment rings when using light blends, however the issue went away when trading out the adjustment rings.
Call/email baratza and you should get it taken care of. Once it gets fixed perhaps stay away from those light roasts, stick to Toscano instead.
I'm having exactly the same problem. Mine grind went to hell after some shipping...... coarse and chunky, and Baratza sent me a great package of the "new" gearbox, white collar, big black ring. I took it to a local repair shop since the gearbox seemed like it would take hours. It returned it to good consistency, but even after re-calibration to the finest setting it was not quite fine enough for my Expobar.
Today, Baratza mentioned that the gearbox had come with shims that could be added to enhance the fine grind capabilities The person who installed the gearbox didn't make the suggested addition of shims. Who knew? I'm kind of surprised by all of this, since it's supposed to be a good grinder for espresso and most of the part had been replaced. I have a Vario as well, which I enjoy, but I thought a second grinder would be handy for decaf without adjusting my "main" grinder.
So, this is my last stab at this machine. I could have bought a new one.
UPDATE: Shimmed to the max and it still isn't quite there on the finest macro setting. Very disappointing. Vario works fine on Macro 2. I really wanted a 2nd grinder for decaf in the evenings. I guess I'll just learn to switch back and forth with the Vario....it's easy to change and i can record what works for each type of coffee to get close.
