Hi, do you have the PRO license? If so, you can set the
oversample resolution on the "Misc" tab . Oversampling is the 'grid' or 'mask' Kisslicer applies to the model for slicing. Normally it's 0.1mm, but for this kind of objects I use 0.04 / 0.05mm. How smaller the oversampling, how longer it takes time to slice.
I use crowning not so much (I have disabled it with-1), but I assume that 1mm is still a good start.
Anyway: the reason of the system of oversampling is giving results a you show unfortunately, making it better with a smaller number.
What I do with those unwanted results is to use Inset (on the style tab) wit slight negative values (so the model gets bigger) with -0.05mm for example. I adjust it so that with the minimum offset it's giving continues lines.
I hope this helps.
