I'm just starting making chocolate at home and use my "Ultra Grinder+" for the second time and I have a small problem about the stones, when I had ingredients, one or the other stop spinning. It is always only one who stop. I cannot see any sugar stock somewhere or anything else, the chocolate isfluidso I don't understand, why one stone doesn't spinne.
Should I worries about that or not and is there anything I can do to fix that? Even if this doesn't damage anything, I imagine this slow down the process as only one stone do the work!
Any advice will be welcome, thanks by advance.
