Thanks for starting this thread. Even though I've had my long arm for 3 years I'm still learning. I bought the Quilt Motion robotics and it's been a big learning curve. Thankfully I had a great tech on the phone last week who helped with my issues and was able to get answers to previous problems that I had. Thanks paper princess for the website on timing, that is an issue that I think I'm having. I get skipped stitches or stitches that look like they are sitting on top.
