That might be the difference.
This has nothing to do with the feed system since the feed dogs are not used to move the quilt when doing ruler work. Lowering the foot as low as it can go would in fact cause exactly the problem I'm talking about if you have areas on your quilt where multiple seams come together because that area can be just enough thicker than the rest of your quilt to cause the foot to catch. That's the difficulty I was talking about.
