[Uneven, rough, curves after slicing]

Thanks @GregValiant for the idea. Even if the offsetting does something unusual, like creating a spline, the outside of the model is formed from the original ellipse, and yet it is having the same problem when I slice it.

Here is the 3mf file. I hope someone can figure it out!

Just please note that I had to use an add-in to export it as a 3mf, and that add-in can only export with poor quality and at a 1:10 scale. I've also included an stl (medium refinement, and to scale) in case that helps.

 

Thanks for the quick replies!

[Uneven, rough, curves after slicing]

Thanks @gr5 and @GregValiant!

 

Some updates: to eliminate issues the thin walls might be causing, I exported just the problem section and scaled it up 300% in Cura.

 

I tried both of the Cure versions gr5 recommended. The Alpha wouldn't slice it at all. The burtoogle version was every so slightly better, but still pretty bad. 

 

I also tried exporting it at different resolutions. In the pics, the top is medium resolution, and the bottom is low. I have the maximum deviation at 0.5, but that's actually what the default was on my profile (Anycubic Mega-S printer). Increasing it to 1mm or even 2 or 3mm sadly didn't help.

 

The curves that I'm having trouble with were made from ellipses that were then trimmed and offset in Fusion if that helps anyone figure anything out.

 

Thanks again for the tips so far!

Thanks for the reply!

1) I did print it, and unfortunately it was just as rough as what the preview showed. 

2) I didn't watch the printing, but I'll try another print and keep my eye on it. I increased the number of polygons and it still had the same rough surface... I didn't think about reducing them.

3) I'll try both versions and see what they can do. Thanks a lot!

 

Hopefully, I'll have a promising follow-up post soon!

Hello,

I am slicing an stl file exported from Fusion 360, but when I do so, a smooth curve is sliced into an uneven, rough shape (see attached). Does anyone know why this is happening, or, more importantly, how to fix it? Thanks for the help!
