Did you check to be sure the finger/lever in the back was fully engaged when you put on the foot? I've had it pop/slip out when I was sewing something bulky so had to keep an eye on it. It wasn't something I could hear but it was clear that the layers weren't moving together.

Well that has surprised me ... I wanted to sew a piece of fabric with fairly stiff interfacing on the wrong side, to another un-interfaced piece of fabric, which was against the feed dogs. I had the zig zag plate & the dual feed foot. But when I commenced sewing it would not feed at all, nothing! I did test the sewing on just plain fabric & it worked.
I then changed the plate to the straight stitch & tried again, nothing! So then I removed the dual feed foot & used the ordinary zig zag foot, Yay, it feeds perfectly. Soooo, I am stumped as to why this is so. I would have thought the dual feed foot would feed fine with a few layers, maybe it was the stiff interfacing in the middle of the two fabrics ...?
