bobbin pulling up

[twinsmom2]

I am working on a very large biker patch - doing satin stitch column outline. The top thread seems to be pulling up bobbin in a definite pattern every few stitches. Changed out the little red wheel, checked bobbin tension, even tried standard actifeed (10) instead of Auto. Fabric is flock with a twill applique over some of it, but seems to be happening on single layer as well as multi-layered areas. Backing is a loose but crisp light woven fabric. Density of satin stitching is 3.8 density. This problem seems to be escalating for no reason. I am on the third try. Any input is appreciated. This is very frustrating.

What version of software? XT machine? Are yo u using auto or standard actifeed?

If you are using auto actifeed, try using the auto lower limit settings under Settings, thread feed and increase it up a cople of points or more. This will increase the amount of thread fed to the design. Use of the "Column feed" on this same page will help also as well as use of the run/fill tool to feed more thread to the stitch to keep it from pulling the bobbin to the top....

Also make sure you bobbin is clean including under the Pressure spring. If you have one chang the case.

Also make sure your tension is set (3 or 4 inch drop on the test)

if tha does not help kick the Lower thread feed limit to about 5.

Can you change these settings in the middle of the design?

Yes just stop and then you can.
