Query: Too coarse

I bought this grinder based on the number of positive reviews, but have not been happy. I have a home espresso machine that is also produced by Capresso, the Model 302. The espresso maker requires a very fine grind to get good flavor from the beans. If the grind is too coarse, the steam runs through the grounds too quickly and the result is watery, more of an Americano than an espresso. Although this particular grinder has settings for a "Very Fine" grind and the instructions indicate it can grind beans for a Turkish coffee, the best I can get out of it is a medium grind that is barely serviceable for drip coffee. I've taken it apart and cleaned it and have looked for other adjustments to no avail. My old spinning blade grinder produced a finer grind than this machine is capable of, and cost 1/10 as much. I am frustrated and disappointed.
