milling grain

I am new to this site and didn't realize when I posted the following in a blog that I really need to post in a forum. Sorry for the double post. Here goes......

I am really new to grinding my own grain at home. I purchased the Family Grain Mill and at this point have not successfully ground any grain. I am using a good quality organic spelt and soft white wheat berry grain. I have tried baking several different things...tortillas, artisan bread, and crackers. At this point I cannot get the grain fine enough. Everything is turning out tough and chewy.
