I have a Bernina 730. I have threaded it correctly. If I pull the material it moves....it was fine last week. It's thin material (felt square) The material does not move on it's own....PLease help.
Are the feed dogs lowered or just not moving? Some machines have a switch to lower the feed dogs for darning and free motion sewing. Look in your manual. hth
Have you changed the pressure on your foot? My machine has a setting that I can change the pressure that is put on the sewing foot depending on the fabric weight. But the feed dogs sounds like a better answer if you've done nothing else to change settings.
Have you checked your stitch length?
