I just made the four main adjustments to my machine as suggested by the gentleman (a design engineer). It's really strange that you can do free motion quilting with the feed dogs up, but this machine can. I guess the problems with proper engineering and factory adjustment makes it possible. If I tried that on my Singer, it would just balk at me trying to move the fabric randomly. But the Jazz 2 doesn't seem to notice the raided feed dogs during FMQing. I just did one test, and will do several more before I expend a hard made quilt to it. Stitches had no problems, other than my need to practise with the machine as it is now. Hopefully I can use this machine for the purpose I purchased it for, FMQing.
