This the the a Fork of the RepRap Java Host Software, which forms RepRapPro's multi-colour/multi-material slicer code. This is a beta-release of this software: it is working, but may still contain bugs. Licence: GPL Download and installation ========================= You need to have Java installed on your computer to run this software. You will almost certainly already have this. To check, open a teminal/command-prompt window and type the command: $ java or, on Windows: C:\> java If you get a load of usage instructions, Java is installed. If you haven't got Java, download the Java JDK: http://www.oracle.com/technetwork/java/javase/downloads/index.html If you are running 64-bit Linux you will also have to install the Java 3D JNI library. For example, in the Ubuntu Software Centre, search for and install "libjava3d-jni". Once you have Java, to install this software download it as a .zip file. To do that click on the little cloud and down-arrow above and to the left on its Github page: https://github.com/sPyOpenSource/slicer which is this page if you are reading this README file on Github. You will get a file called host-master.zip. Unzip the download anywhere you like on your computer, say in a directory called my_download. Some versions of Windows have difficulties if there are spaces in any of the folder names in the tree where you put the download. Replace them with the underscore. For example, if you want to download into: C:\Some Folder\MySubFolder\My Other Folder change the names to: C:\Some_Folder\MySubFolder\My_Other_Folder To run the RepRapPro Slicer Software ==================================== java -jar Slicer.jar User Documentation ================== For details of how to use this software, see: http://reprap.org/wiki/RepRapPro_Slicer Upgrades ======== As described here: http://reprap.org/wiki/RepRapPro_Slicer_Variables when you first run this software it creates a copy in your space of all its configuration files. If you later download upgrades from Github, your configurations will not be overwritten. That way, if you make adjustments, you keep them from one upgrade to the next. All the configuration files are placed in a directory called .reprap in your home directory on your computer (note that the initial "." in the name means that this directory is hidden - you have to enable the viewing of hidden files to see it). If you decide you want to revert your configuration to the standard one, then rename the .reprap directory to, say, .reprap.old then run the software. It will now not find .reprap, and so it will create you a new .reprap containing copies of the standard files from your download. One thing you may well want to preserve even if you do this is the offsets of the heads in your Tricolor RepRap that you have set - these are unique to your machine. (See here: http://reprap.org/wiki/RepRapPro_Multimaterials#Step_5_-_Registration for how to set the offsets.) These offsets will be in the file prologue.gcode in the directory .reprap.old/Mendel-0.5mm (or whatever RepRap machine you are using). Compare that file to the version in .reprap/Mendel-0.5mm (they are quite short). Edit the new file to change the G10 lines to set the offsets for your machine. Experiment with the source code =============================== Download a copy of the NetBean Java Development Environment: To run the software in the development environment open: slicer->src->org.reprap right click on Main.java and select Run as->Java Application and the slicer should run. You can then edit the source code and do what you like with it... X. Wang 12 May 2020
