Cant produce anything round

[Benhock027 0]

Hi,

Every time I load any model into Cura that has round surfaces, it makes it very faceted and polygon like. It then of course prints this way too.

Can anyone help.

This is your cad software - when you export from cad to stl you can set how many line segments appear in a given arc. (stl format doesn't support arcs and cura doesn't either) Some cad programs do this in distance possibly "error" which might be in mm. Some do it in degrees/angle.

But beware - if you set this too precise it will create too many points and your printer (assuming it has marlin in it - for example 99% of printers on the planet) then it can only plan out 16 points ahead of time and if those 16 points are all in the next 4mm it will slow down like crazy on corners and print ugly corners. So there is a happy medium between more points on a curve and not too many.
