Maybe picking up a dead thread but I too just picked up a Chandler 217 with the cam box but only one cam.  I'd really like to find the 3 and or 4 point zig-zag cams if anybody knows of a source?

I tried to 3- print them 

worked but i was not 100 % satisfied

the Bernina favourite (household machine) shares the same hook and has the same cams inside

I bought one for the hook and finally pulled the cams out: they are the same as the old bernina 217 cams

the global has an other size cambox and cams i believe

So I bought a stack of cams from a Bernina 830 in hopes of happening upon a 3 stitch zig-3 stitch zag cam in the stack.  Closest I got was a serpentine zigzag with about 9 stitches in a repeat.  So used the cams to engineer a cam to do the 3 stitch zig-3 stitch zag.  It took me a couple of tries but I got it.  Lucky to have a neighbor with a 3D printer to test the design.  Here's a picture of the results of the first and second try, the 3 stitch zigzag and the serpentine cam from the 830 along with a video link.  And a copy of the .stl file in case you want to print one for yourself.

That's good work! We have a section of the forum where people can share digital and laser printer design patterns and programs.

Nice work,

After i made my cams i figured out that by making them a little larger i could make my stitch with also wider.

i bought a wider feed dog needle plate and foot from global (which fitted my older bernina) and was able to enlarge my stitch with

From small to much wider

The stitching on my cam happens at 4 difference radii measured from the center of the cam, from smallest to largest they are 27.8, 28.5, 29.3 and 30.0 mm.  This range drive the needle through the full 6mm of zigzag travel.   How much larger did you go?

I think my machine could go even wider as the first thing the needle hits is the slot in the presser foot.  I'll look into getting one at Global.

I can also put the file in another location but can you point me to the section you think is best?

I recently picked up a bernina that has the fancy stitch cam,  and in the manual it references both cam styles, the small cams and the larger style one which is what the globals come with ( i also have a global 217 with 4-point). So some bernina 217s came with the small cams and others with the larger one?

I had a few manuals that went with the machine -- Adjustment Manual, Instruction Book, Owner's Book, and Parts Book. I had scanned the books and if you're interested, send me a PM with your email address and I'll send you copies.
