The settings for balancing have nothing to do with the fabric you are holding and sewing.. What they will change is how much the fabric will move on the machine with the feed dogs. It's like balancing a buttonhole. If one side of the buttonhole is too long, you either shorten or lengthen the other side in the software in the machine. You don't drag or pull the fabric to balance. The same goes for side to side balance.
Looking at the screen for a newer Pfaff - it looks a lot easier than the older models!
