fix typo that put things in the wrong position use int() builtin instead of POSIX::floor() fix typo use alternate method of creating local routines remove aliases for new duplicate option use coderefs for linear interpolate function, make binary insertion sort inline add \n at end of die message regarding too many objects for print area fix case where no duplication is done fix whitespace according to slic3r coding style assume 200x200 bed area if center is 0,0 Some cleanup to the autoarrange duplication logic

_Q: Oh cool, a new RepRap slicer?_
|
|
|
|
A: Yes.
|
|
|
|
# Slic3r
|
|
|
|
## What's it?
|
|
|
|
Slic3r is an STL-to-GCODE translator for RepRap 3D printers, aiming to
|
|
be a modern and fast alternative to Skeinforge.
|
|
|
|
See the [project homepage](http://slic3r.org/) at slic3r.org
|
|
for more information.
|
|
|
|
## What language is it written in?
|
|
|
|
Proudly Perl, with some parts in C++.
|
|
If you're wondering why Perl, see http://xkcd.com/224/
|
|
|
|
## What's its current status?
|
|
|
|
Slic3r current key features are:
|
|
|
|
* multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required;
|
|
* easy configuration/calibration;
|
|
* read binary and ASCII STL files as well as AMF;
|
|
* powerful command line interface;
|
|
* easy GUI;
|
|
* multithreaded;
|
|
* multiple infill patterns, with customizable density and angle;
|
|
* retraction;
|
|
* skirt;
|
|
* infill every N layers (like the "Skin" plugin for Skeinforge);
|
|
* detect optimal infill direction for bridges;
|
|
* save configuration profiles;
|
|
* center print around bed center point;
|
|
* multiple solid layers near horizontal external surfaces;
|
|
* ability to scale, rotate and duplicate input object;
|
|
* customizable initial and final G-code;
|
|
* support material;
|
|
* cooling and fan control;
|
|
* use different speed for bottom layer and perimeters.
|
|
|
|
Experimental features include:
|
|
|
|
* generation of G2/G3 commands for native arcs;
|
|
* G0 commands for fast retraction.
|
|
|
|
Roadmap includes the following goals:
|
|
|
|
* output some statistics;
|
|
* support material for internal perimeters;
|
|
* new and better GUI;
|
|
* more fill patterns.
|
|
|
|
## Is it usable already? Any known limitation?
|
|
|
|
Sure, it's very usable. Remember that:
|
|
|
|
* it only works well with manifold and clean models (check them with Meshlab or Netfabb or http://cloud.netfabb.com/).
|
|
|
|
## How to install?
|
|
|
|
It's very easy. See the [project homepage](http://slic3r.org/)
|
|
for instructions and links to the precompiled packages.
|
|
|
|
## Can I help?
|
|
|
|
Sure! Send patches and/or drop me a line at aar@cpan.org. You can also
|
|
find me in #reprap on FreeNode with the nickname _Sound_.
|
|
|
|
## What's Slic3r license?
|
|
|
|
Slic3r is licensed under the _GNU Affero General Public License, version 3_.

|
|
--bridge-flow-ratio Multiplier for extrusion when bridging (> 0, default: 1)
|
|
|
|
|
|
|
|
If you want to change a preset file, just do
|
|
|
|
slic3r.pl --load config.ini --layer-height 0.25 --save config.ini
|
|
|
|
If you want to slice a file overriding an option contained in your preset file:
|
|
|
|
slic3r.pl --load config.ini --layer-height 0.25 file.stl
|
|
|
|
## How can I integrate Slic3r with Pronterface?
|
|
|
|
Put this into *slicecommand*:
|
|
|
|
slic3r.pl $s --load config.ini --output $o
|
|
|
|
And this into *sliceoptscommand*:
|
|
|
|
slic3r.pl --load config.ini --ignore-nonexistent-config
|
|
|
|
Replace `slic3r.pl` with the full path to the slic3r executable and `config.ini`
|
|
with the full path of your config file (put it in your home directory or where
|
|
you like).
|
|
On Mac, the executable has a path like this:
|
|
|
|
/Applications/Slic3r.app/Contents/MacOS/slic3r
|
|
|
|
## How can I specify a custom filename format for output G-code files?
|
|
|
|
You can specify a filename format by using any of the config options.
|
|
Just enclose them in square brackets, and Slic3r will replace them upon
|
|
exporting.
|
|
The additional `[input_filename]` and `[input_filename_base]` options will
|
|
be replaced by the input file name (in the second case, the .stl extension
|
|
is stripped).
|
|
|
|
The default format is `[input_filename_base].gcode`, meaning that if you slice
|
|
a *foo.stl* file, the output will be saved to *foo.gcode*.
|
|
|
|
See below for more complex examples:
|
|
|
|
[input_filename_base]_h[layer_height]_p[perimeters]_s[solid_layers].gcode
|
|
[input_filename]_center[print_center]_[layer_height]layers.gcode
|
|
