Does Cura generate G2, G3, or G5 commands?

[Xeddog 6]

I was just looking through my Marlin configuration and see that Arc Support is used to process arcs via G2 and G3 gcode commands, and Bezier Curves via G5.  I have looked through several of my Cura generated gcode files and there are no G2, G3, or G5 commands in any of them.  One was a cylinder so I would have expected many arcs in that one.  So if Cura doesn't generate these codes I can disable them in Marlin and save a little memory.

Cura does not support curves. It only loads polygonal models which don’t have true curves; only estimations of curves by multiple flat polygons.

Thanks.  That's what I thought.  I just wanted to make sure.

If file size is an issue - you can use Arc Welder which intelligently converts endless strings of G0 & G1 codes into G2 & G3 codes. Cuda has an Arc Welder plugin which does this post-processing conversion.

But Cura doesn't do it natively - I can't see that you'd gain much if Cura did as you'd get pretty much the same result at the end.

Thanks Posital.   I have been using Arc-Welder since it's beta, and of course I have added the Cura Plug-in.  I asked the question here before Arc-Welder existed.
