|
// ---------- NOTES FOR A PROPER RENDERING IN OPENSCAD -----------
|
|
// First of all, make sure you are using the latest version of OpenScad (>= 2014.05.31)
|
|
// Then, it is important to change a default setting. Go to: Edit --> Preferences --> Advanced
|
|
// And increase "Turn off rendering at 2000 elements" to a larger number like 20000
|
|
// -------------------------------------------------------------
|
|
|
|
// ---------- GENERATING THE STL FILES ------------------------
|
|
// In OpenScad, it is possible to preview designs (F5 key) or to render them (F6 key)
|
|
// to be able to export them as STL files ready for 3D printing.
|
|
// Please note that some parts will only be present in the preview, but not in the
|
|
// final render. This is normal, as they are used only as a reference and do not need
|
|
// to be 3D printed.
|
|
//
|
|
// The main file that needs to be opened with OpenScad is Cyclone.scad (this document).
|
|
// From here, it is possible to select most of the parts, using the root modifier (!).
|
|
// Place it before a function to exclusively render that subtree. When used, for instance, as
|
|
// !Cyclone_Y_frontFrame();
|
|
// it will show only the frontal Y axis frame. Rendering it with F6 will output only
|
|
// that part, which will be ready to be exported as STL.
|
|
//
|
|
// It is also possible to generate larger STL files that contain multiple elements,
|
|
// and afterwards split them. This can be achieved with a software like Cura, that
|
|
// also allows easy rotation and positioning of the models for printing.
|
|
// To split STLs in Cura: right click over the part --> "split into parts"
|
|
