Just got my new toy tonight and followed the video posted for unboxing and setting it to the finest setting. I ran through 600 grams of soft white wheat at the fine setting (one smidge above where you hear the stones touch) and it finished the job in 2 min 36 seconds. Flour temp was 104.7 F.
I started with rice on a course grind just to run some though to take off any manufacturing residue as a precaution. Eventually ran the rice through on the finest setting. I am not even sure if flour is the right word- dust is more like it! Unbelievable how fine this thing mills compared to my Nutrimill Classic. I love this thing!!
