All of a sudden my walking foot is skipping stitches. i cleaned my machine and changed my needle, but it's still happening. any advice would be appreciated. thanks

sounds like there might be some threads caught between the tension discs. Try using a small strip of fabric to 'floss' between them. You might also have some thread caught in the hook assembly.

Hi, I am a Bernina tech and can tell you what the problem is. The problem is that the spring on your BSR is weak. Bernina has an upgrade to adding a heavier spring that solves this problem. The older lighter springs on the BSR is shiny. The newer heavier updated spring is dark. Ask your dealer/tech to change this spring to a new one or give you a newer updated BSR. Also be sure they updated the BSR to the latest firmware.

Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out.

You may need to increase the foot pressure to cope with the heavy denim material. Look carefully at the material as the machine tries to stitch ... if the foot is not keeping the material firmly on the stitch plate, it might be riding up on the needle (denim tends to be rather 'grippy') which will prevent the thread loop being formed correctly below the stitch-plate and therefore not getting picked-up by the CB hook. Changing to a bigger diameter needle might actually make the situation worse in this case ... go back to an 80 and try again.
