Machine repair
Took machine to repair. With experience was easy fix. The repairman has 5.0 rating-that’s right; perfect. Told him problem and left sample of fabric giving fits. He fixed part of problem. I Tested machine with provided fabric. Not one stitch. Yep! Didn’t make even 1 stitch. He said it needed walking foot. NOT!. I do free motion quilting. After swallowing his pride, he fixed it in ~1minute=easy fix.
Lesson; even the best aren’t perfect. Test drive before driving 1.5 hours home.
