I've had my HQ16 for several years(7) and have never felt comfortable quilting with it. Subsequently, haven't used nearly as much as I would like. In regulated mode, when I first press Start the machine takes off like a house a fire. There's no such thing as a slow start. It does calm down somewhat after a few seconds, but it never seems to want to go at a very slow pace. I always feel like it's rushing me. Is this normal response, or could there be something that needs adjusting?
