OK I got this by discovering that it doesn't like big changes in parameters at once, but little by little.

To get it to Outer_circle_rad 57mm, I had to step from 65 mm to 61 mm and only then to 57 mm.

If I tried a bigger change directly from 65 mm to 60 mm the design went crazy.

So it seems temperamental but with a bit of coaxing you can get it there.
