Yes, I was just reading the manual, and the cams are built-it. I will need to find the pattern wheel. Nothing seems to be gummed-up. The reverse was a little sticky, but is OK now. This machine has 14 attachments, including a hopping foot for free-motion embroidery or quilting. It looks like it was hardly used. The couching foot still has the string through the hole. That foot is my favorite way to do ruffles / gathering. We are going to be friends.
