I had my machine on a wood floor in an upstairs room. At the time I had a wooden grace frame. When I quilted the viberation of the machine would viberate the frame out of balance. We moved the machine downstairs to a room with carpet and a cement floor. Then I also went to the dealer in Houston and bought the frame that goes with the machine. No problems now. I did learn that when you buy a machine you should buy the frame that is recomended for the machine. The reason I had the wooden frame is another story.I really don't like the carpet on the floor but it is there so I would rather leave it than fuss with DH about removing it.
