Frequently Asked Questions
What makes the IDT system better than a standard walking foot? Unlike a bulky, clip-on walking foot that can block your view and rattle as you sew, PFAFF's Original IDT system is fully integrated into the internal mechanics of the machine. It works silently and matches the feeding speed of the bottom feed dogs exactly, keeping thin background fabrics and thick quilt sandwiches perfectly aligned without shifting.
Can I lower the feed dogs for free-motion quilting? Yes. The quilt ambition 635 features an easily accessible external lever to drop the feed dogs completely. Combined with the included Open Toe Free-Motion Foot, you can guide your fabric smoothly in any direction for echo quilting, thread sketching, or stippling.
What is the benefit of the Bobbin Thread Sensor? The sensor continuously monitors the thread on your bobbin. Instead of running out of bobbin thread in the middle of a complex decorative stitch or a long quilt seam, the machine alerts you on the color touchscreen when your thread is low, so you can stop and refill it before the seam breaks.
