Pasta maker tips/tricks/recipes?

My hubby bought me a pasta maker (roller?) at a flea market for $5 and I am hoping someone has tips/tricks to using it. It did not have the book of course but I have found a few articles about making and rolling the dough but I want advice from a "real" person. So, anyone have tips? Recipes for pasta and/or filling for raviolis and things? Thank you!
