I have a Brother CS6000i and if you hold the + sign while turning it on, it will set the default position permanently to the center (or until you manually do this again to change it back to the left). I was changing it to center EVERY time I turned it on until I read my manual and discovered I could change the default position from left to center where I need it to be every time. Check your manual -- if you have an electronic machine you can probably easily change the default position!
