Anyone have this problem with Juki TL98Q?
My Juki is on a frame and quilting ok, but when I push the button for needle up, the needle will go up & down several times before stopping. When it does stop sometimes the needle is up, sometimes down & sometimes it's half way in between. Anyone know what's going on? It's an older model Juki. If this has happened to you, is it expensive to repair?
