I have two Brother machines of my own and have used other machines. Almost all of them dance if placed on the wrong type of surface. When I attend my weekly quilt along meeting the tables we use are 8 foot long plastic table. It dances all over. I just slow down on those days. Once back at home or any other place where I can place machine on sturdy wood surface such as my sewing cabinet it doesnt dance with me. Trust me its not your machine.
