This is merely terminology, but the Juki is not a longarm. Longarms typically have 18" or more of throat space, while the Juki (if I remember correctly) is about 8.5". Some of the problems and techniques will be the same for the Juki and for a longarm, but many will be different. You may have better luck rephrasing your title to ask for information about quilting with the Juki on a Grace Inspira frame. There are lots of YouTube videos that may help you, and I think there's a yahoo group devoted to quilting on the Gracie, as well as several others for Juki users.
