If step is set to 0.003, there's a gap in the figure. 0.002 and 0.001 go back to no gap. That's all I tried. The difference is that 0.003 doesn't fit evenly into 1 so the for loop needs to be adjusted to compensate.

It will look better if the step size evenly divides the range, but if you
really want to use a stepsize that does not, add closed=true to the
path_sweep call in order to close the shape. That will eliminate the gap.

Adrian, I added closed=true and it threw up a syntax error. So I updated
my bosl2 from github- no difference. If I change it to closed=false it's
happy, but it won't work with closed=false.
Any ideas?

I got an error when I used closed=true with a step that divides evenly into 1 but when the step doesn't divide evenly into 1 the closed=true works (no error message and no gap in the structure).

more generally the equation will be of the form

path=[for(t=[0:359])
[10cos(pt)(a+cos(qt)),

you can vary the values of a, p and q

If step is set to 0.003, there's a gap in the figure. 0.002 and 0.001 go
back to no gap. That's all I tried. The difference is that 0.003 doesn't
fit evenly into 1 so the for loop needs to be adjusted to compensate.
If you start out with:
numsteps = 200;
step = 1/numsteps;
it'll be obvious if you put in a non-integer.
