If it is recessed, I still think it is a drag issue. Maybe the weight of the quilt dragging off the edge of the table directly in front of you?
If it isn't a recessed set up you could try piling up some phone books or something to have a larger surface area for the quilt to rest on as you are feeding it into the machine. A long time ago, someone posted a picture of their setup. They got some of the really thick foam insulation and built a surface all around their machine bed so everything was level with it. Another option is the one Dunster described building a system hanging from the ceiling to support the quilt's weight.
Hello Feline Fanatic. After considering this and presser foot pressure, I did some experimentation and found the presser foot pressure has had a very good effect. Still not right but getting closer. As soon as I can get back to sewing, I will adjust my table setup as well. The table behind my sewing surface is a foot shorter than the surface. Luckily, its height is adjustable. I will work with it today. I'm feeling optimistic about these changes and hope to post a picture of consistent stitch length. Thank you!
