Installing RepRap on your computer
The RepRap software currently supports 32-bit Linux and Microsoft Windows. We are working on adding Mac and 64-bit versions.
You will need Java on your computer. If you don't have it already, get it here:
You will also need to download and install the Arduino development environment to build the firmware for your RepRap machine. That is available here:
Finally in this prerequisites section, you will need to download and install the Sanguino add-ons for Arduino. Get them here:
Start by downloading the RepRap distribution from Sourceforge:
There are a number of files and packages from the project available there, but the main download (which is about 65 MB) will have a name like reprap-nnnnnn-yyyymmdd.zip. This is the one file you want. It is the main Sourceforge download for RepRap; nnnnnn is the name of the current RepRap machine and yyyymmdd is the date of the release.
You can install and use RepRap in your own file-space under Linux. If you want it to be available system-wide to all users (see below), you will need superuser privileges.
In your own space
Unzip the downloaded file:
$ unzip reprap-nnnnnn-yyyymmdd.zip
This will create a directory called reprap-nnnnnn-yyyymmdd.
