I use 5.5 or 5.4 with my 1/4 inch walking foot and 3.8-4.0 for my regular 1/4 foot. You can set those as memories in your 1-4 stitch positions.
I have found that when I cut my my Accuquilt Go I have to skinny up my stitch. Seems I cut on the outside of the line when I rotary cut and the Go must go to the in or just a smidgeon inside the line.
