Niche Zero: Cleaning & Calibration 

no, it's just a marker. it would be unnecessary. when you twist all the way, nothing about the dosing funnel tells the grinder when to stop, it's the burrs. the calibration dot is then used mark that stopping point and to tell you how it relates to the grind size marks, because neither the calibration or the dosing funnel knows when to stop. the threads do not tell you when to stop, and that makes sense if you change burrs as they will have a different stopping point.

@@mescellaneous Thanks for the response, but I solved the problem that was causing me to ask that question 10 months ago haha. Useful info in case anybody else comes by who is having an unknown issue that makes them start to question silly things like this. When I was breaking in my grinder I had some issues that were resolved by taking it apart and cleaning it a couple of times, as the burrs weren't aligning properly I'm guessing due to debris, so when I took it all the way to the finest espresso setting it was still almost french press coarse. I asked this when I was troubleshooting why that was happening :)

It says it underneath each setting FINE........ ESPRESSO.....FILTER. If making espresso put in in espresso and than add or subtract each notch to your liking, if your espresso is to fine your machine won't drip any 💧 if it's to coarse than I'll drip to fast. So adjust till it's right, each bag of coffee beans has its own setting that you'll need to adjust to, you'll waist a few shots till you get it right but than leave it on the seating till you get a new bag of coffee
