Has anyone had problems with their grinder accumulating grinds in the exit port of their Rocky? If I don't remove the chute and clean out the discharge port, each time I fill the portafilter, I won't be able to fill one, a second time. I roast my own coffee beans and do use a real fine grind setting. I'm wondering if there is an easy fix to this problem. It never happened before, when I was using previously roasted beans, just since I have been roasting my own. Is there a correlation? If so, what is the solution?
