My 1500th blip! Practically forgot about it as the mill got stuck in the morning, so I had to dismantle it to see what's wrong. It made the rest of the day quite busy and no particular ideas to celebrate the milestone came to my mind.
The reason for the problem was the "porridge" on the right roller. I have mixed a little bit of not-exactly-dry oats in the mixture (to get rid of it before the spring and warmer weather) and it doesn't seem to work in cold weather.
PS. I didn't count the grains. Probably a lot more as 1500 is just about 50-60 grams.
