@ -46,12 +46,12 @@ Slic3r current features are:
|
||||
* center print around bed center point;
|
||||
* multiple solid layers near horizontal external surfaces;
|
||||
* ability to scale, rotate and multiply input object;
|
||||
* customizable initial and final GCODE (using command line only);
|
||||
* use different speed for bottom layer and perimeters.
|
||||
|
||||
Roadmap includes the following goals:
|
||||
|
||||
* output some statistics;
|
||||
* allow the user to customize initial and final GCODE commands;
|
||||
* support material for internal perimeters;
|
||||
* cool;
|
||||
* other fill patterns.
