Question about Bernina Activa 140
I have a Bernina Activa 140 and need to use 12 wt thread in both the upper thread and the bobbin, stitching 2 layers of cotton fabric and a layer of cotton damask together. I have tried several needles types and sizes including size 80, 90 and 100, different tension settings for upper thread and bobbin thread and tried lengthening my stitches. The stitches just won't come out nice and strait and look a bit wobbly. Has anyone had success with using 12 wt thread in this manner and what settings and needle gives nice stitch results?
12 wt thread generally will not work well in the bobbin...
"Aurifil 12wt Thread
Aurifil 12 wt thread is ideal for hand quilting, big stitch hand quilting and machine quilting. 12 weight thread creates a more defined and often primitive look. It's great for designs that use a longer stitch length if using a machine. When machine quilting with 12 wt thread, use 40 wt in the bobbin, increase your stitch length, lower your tension, use Topstitch size 90 needles and stitch slowly."

SOURCE: i have an 1130 bernina
The 1130 does not have a consumer adjustable presser foot. Check to be sure you are using the correct presser foot .Some feet are slightly different in height which is how the pressure is regulated. If this is not your problem it will need to be seen by a technician.

Are you absolutley sure you're not getting a problem with stitch formation on, for example, wide zig-zag. Check again, using a different colour top and bottom and make sure that the stitch is being formed properly with only the top colour on top and bottom colour on the bottom. It sounds as though the bottom loop is not being picked-up by the hook properly. Make sure you've thoroughly cleaned-out any fluff under the stitch-plate and remove the hook/shuttle and give the hook race a good clean and give it a single drop of oil, even if you've got the lightweight part-plastic hook/shuttle fitted.

it's very possible that the machine is slightly out of time & needs to be service at a sewing machine shop
is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?
is the bobbin in correctly?
is the bobbin warped?
