Hey! I have the Bernina 1008...mine has a knob on the right hand of the machine, near the bottom...that knob drops the feed dogs on mine and it may do the same thing on yours. And it's easy to have them dropped for something and then forget to raise them up again...and it won't move! If it's not that, I agree with checking the feed dogs to make sure they're not lint-impacted; next step would be a call to your dealer. And I hear your "sigh"...mine has to go in this week for a bobbin holder problem. Good luck!
