My feed dogs would not raise into the proper position no matter where the lever was set. After numerous unsuccessful trips and complaints to the dealer where I bought it, I finally took it to another repair shop where it was diagnosed as missing a screw inside the machine that should have been there all along. Once that was finally in the proper position, I could sew and FM quilt. Before the screw, they wouldn't fully go down either which made it impossible to do any free motion quilting. One missing screw made for a very miserable year with a brand new machine.
