I've had that machine since it first came out, almost 10 yrs & love it, it is super, super for free moton. Hints-I find it is better for free motion when it is threaded thru all three holes on that top thingy, there is a picture in the manual, but a nuisance to get floppy thread thru all 3 holes so when I change thread I just tie the ends of the new spool to the ends of the thread from the old spool & pull it thru. Of course the knot won't go thru the needle so at that point I thread the needle manually, do not like the automatic threader.
Also when doing free motion use a stretch needle, size 14, no loopies, no missed stitches. This information was from a Brother tech when I first got the machine, really the best hint ever.
