This is so helpful! I know this is from an old post, but I am a newbie at quilting on a frame. Just purchased the Viking Mega quilter and Inspira frame from a lady in Tennessee. After taking apart and moving, it sewed perfectly the first time with no adjustments! My only disappointment was the bowed panto shelf. This is such an easy fix, can't wait to try this. I'm still practicing, anxious to do an actual quilt top now. Thank you!!!
