My new machine is working out great to sew my puffy pillows together for my puff quilt.  I had to change the needle to a much smaller and shorter one. So that threw off the timing and the tension was set so tight that it was cinching up the fabric. Even the bobbin was winding so tight. I always have to reset everything when I bring home a new industrial. The real test will be when i go to sew a banner using nylon fabric and zigzag as fast as i can go.
