I have a Janome Horizon 8900. I have used the serpentine stitch with the walking foot for the majority of my quilting with no problems. I can adjust the length and width of this stitch. Then I wanted to try zigzag stitch with the walking foot. I posted a question to the Janome forum asking about the zigzag and walking foot. I was told also not to try to go in reverse, use the correct plate (not single hole), and would not have a problem with zig zag. I only used the default settings. There is a setting 9 and 10 for the zig zag. I used 10 which was for the right zig zag. I would have preferred wider and longer zig zag but was afraid I would break a needle or walking foot. It did zig zag.
