Hi Dave,
here is the 50mm cylinder in high resolution.
If slic3r follows the original resolution it should generate 360 segments.
I know, this restriction is because a standard RepRap controller can not handle such a data flood.
But i have a very fast CNC controller with ethernet connection.
So he can handle 0,2mm segments at 400mm/sec and more...

I forced the output of my CAD Software to decrease the number of vertices.
Output resolution is now 2° (180 segments)
Now Slic3r generates 188 segments.
How is that ?
I am very confused...

Hi Dave,
I did some more experiments...
Let's say 128 is the highest number of segments for a "50mm cylinder", that slic3r can produce.
Now a simple calculation :
50*3,14= 157mm circumference
157/128=1,23mm radians
So let's just say we have a segment length of ~1,23mm (mathematically not correct because we have 128 chords of a circle)
Than i did a slice of a "10mm cylinder" with 1° angle resolution.
The output from slic3r was 64 segments.
Same calculation again:
10*3,14 =31,4mm circumference
31,4/64=0,49mm radians
As you can see, the "segment resolution" for a "10mm cylinder" is much higher.
This means the presumption of a "minimum segment length" restriction is not correct.
And it confirms your observation with small diameters.
But how can i force slic3r to produce shorter segments for large diameters ?
By the way...
With CURA now i could reach 350 segments for the 50mm cylinder, by tweaking the triangle output of my CAD software.

What poll or survey shows most use SD card?
I would suppose MOST use computer software (repetier-host, Printrun / Pronterface ,
Replicator G / Makerware, XYZ DaVinci )
to drive 3D printers?
and
115200 baud can keep up with any mechanical system.
