Yep, number on problem with FMQ, we forget that the tension disks need tension and the pressure foot needs to be down....
One way to check just before you put pedal to the metal pull on the top thread.... if it zings through your needle without any tension your pressure foot is still up. If it takes a little more effort to pull the thread through it is down. To test try it when you have your 'piecing' foot on...
