Hi all,
I'm new here too, and new to 3D printing, and running into a similar problem. If I don't have "Only follow mesh surface" ticked, Cura only generates Gcode for the end of my object (code size is 15KB).
If I do have it ticked code size > 400KB, but it doesn't print anything but the mesh surface. No flat end, no raft (if specified), no brim (if specfied).
The part I'm trying to print is downloaded from http://www.thingiverse.com/download:108451
I'm scaling it down 50% so it fits my little printer, but the same applies if I print it full size.
Xray view doesn't show any red lines.
Changing the shell width didn't seem to help.
Frank
