RepRap Distribution Files
When you download the RepRap distribution from Sourceforge here you will get a file called reprap-nnnnnn-yyyymmdd.zip. The nnnnnn is the name of the current RepRap machine ("mendel" at the time of writing), and yyyymmdd is the date of the release. When you unzip that file it will create a directory called reprap-nnnnnn-yyyymmdd. This page tells you what's in that directory.
Licences and README
There are three files in the directory for these:
LICENSE README README.txt
The README.txt is the same as README; it's just there because Windows likes to have file extensions to hold its hand when it's deciding what to do with things. These three files are pretty self-explanatory.
Programs you run
There are two of these, one for Linux and one for Windows:
These are both scripts. When reprap is run on Linux, and when reprap.bat is run on Windows, they configure the computer correctly then run the RepRap host software that allows you to build things in your RepRap machine.
That host software needs some data files. These are:
reprap-icon.png reprap-wv.stl reprap.properties.dist rr-logo-green-url.png
The reprap-icon.png file contains the RepRap teardrop.
The reprap-wv.stl contains a model of the RepRap machine's build platform that the host software displays in 3D for you to load parts for building onto.
The reprap.properties.dist file contains the default parameters for the RepRap machine. Those are described in detail here.
The rr-logo-green-url.png file contains another version of the logo that the software uses in it's main control window.
The RepRap source files
All the designs for the RepRap machine (mechanics and electronics) together with the firmware that resides in the machine's microcontrollers are in a directory:
You may want to move that directory elsewhere on your computer for ease of access.
The source files for the Java RepRap host software are in the directory:
These are the files that you need to run RepRap on your computer. The main one is:
This is the actual RepRap Java program. There is then a bunch of Java libraries that RepRap needs:
RXTXcomm.jar j3d-org-java3d-all.jar j3dcore.jar j3dutils.jar swing-layout-1.0.3.jar vecmath.jar
There are also Linux-specific library files:
libj3dcore-ogl-cg.so libj3dcore-ogl.so librxtxParallel.so librxtxSerial.so
And Windows-specific library files:
j3dcore-d3d.dll j3dcore-ogl-cg.dll j3dcore-ogl-chk.dll j3dcore-ogl.dll rxtxParallel.dll rxtxSerial.dll
