The same is really true of any of the SS machines. And if the stitches are a little left and right of where you're trying to sew, that's what you're seeing. if the stitches are straight but the thread sort of waves from one side of the hole to the other side of the next hole, that's just the thread, the knot and the fabric dancing.
