Problem with Bernina foot 96 with cup
I have been using the number 9 foot with my Q24, everything perfect, then I switched to the number 96 foot with cup and my stitches became very erratic - skipping stitches and the machine sounding different, as if it were slowing down and then "lunging" forward - never did either of these things. I rethreaded the machine, changed the needle and checked the bobbin thread tension with the gauge - didn't make any difference with the number 96 foot, until I went back to the number 9 foot, then the machine stitched perfect again! Anyone ever see this?
