Hi all! I'm practicing on our new Artistic on a Majestic frame. Everything has been going fine - on my 2nd practice round, working on fixing the tension and trying not to over ride the stitch regulator and get giant stitches, when the machine started humming loudly. I was moving the quilt up for a new section, so I turned it off. When I turned it back, it started slowly stitching, even though it wasn't set to stitch. Has anyone else experienced this? It kind of felt like when something is accidentally pushing on the foot pedal for a standard machine.
