RepRap X2V3

Overview Hardware Electronics Firmware LCD Support Host Software & Printing

Host Software

X2SW Software Bundle There are no specific requirements for the host software to transition from RepRap X2 to X2V3. The latest versions of X2SW Software Bundle will work for both X2 and X2V3 as well as usual single extruder printers. Starting with the version 1.1.0.7 the RepRap X2V3 profiles are bundled with the installer. It is however recommended to upgrade to version 1.2.x.x to realize all the benefits of the dual extrusion printing. The latest profiles can always be loaded using X2SW profile manager from the online repository (chose under "RepRap/X2V3" branch in the profile tree). The X2SW profiles contain in itself the configuration of the printer UI and various slicing profiles for Skeinforge and Slic3r slicers bundled with the software package. As the new profiles get published the announcements are posted on the forum pages of the web site.

Skeinforge

Here is the list of the Skeinforge slicing profiles available at the moment: In order to choose a profile go to "Settings->Slicer Settings" and pick the desired profile in the "Profile Selection" drop-down box. Then slice the model by opening its STL file in the Pronterface UI. After slicing is finished (might take a while for complex objects) it's ready to be printed.

ABS-0.35-Parts
This is a standard single extruder ABS printing profile.
How to print: ABS-0.35C-BASE and ABS-0.35C-INSERT
These profiles should be used together. The model has to be represented by 2 STL files. The first one will be printed with material loaded into extruder 0. The second will be printed using extruder 1. The second material can be ABS of different color or HIPS for printing manually generated support. The profile can be tweaked to work better with other than normal ABS or HIPS materials. For example it can be a conductive plastic or plastic with different properties for improving the final object flexibility or strength. The example of printing ABS inside HIPS support can be seen in the beginning of the video here http://www.youtube.com/watch?v=AEW-DNo0GxI.
How to print: ABS-0.35D-Parts
This profile is for printing in ABS. It prints the same object from both extruders simultaneously. It's done by making the extruder 1 motors copying the steps made by extruder 0. The extruders have to be identical and use identical filament to achieve good results. The printing volume is reduced to 100mm on the X axis when this profile is in use.
How to print: ABS-0.35DM-Parts
This profile is for printing in ABS. It prints the mirrored copy of the object from the second extruder. It's done by making the extruder 1 motors copying the steps made by extruder 0 but some of them in opposite direction. The extruders have to be identical and use identical filament to achieve good results. The printing volume is reduced to 77mm on the X axis when this profile is in use. The example of printing two symmetrical parts for X2V3 machine using this profile is shown in the following video http://www.youtube.com/watch?v=9c2cHfZs8kg.
How to print: ABS-0.35S-Parts
This profile is for printing in ABS from extruder 0 with Skeinforge generated support printed in HIPS from extruder 1. The example is the model of a cat shown in about 2 minutes from the start of the video here http://www.youtube.com/watch?v=AEW-DNo0GxI. Skeinforge uses the same settings to generate G-code for printing the object and the support structures. Therefore, the filament of identical diameter has to be used in both extruders.
How to print: PLA-0.35-Parts
This is a standard single extruder PLA printing profile.
How to print: PLA-0.35C-BASE and PLA-0.35C-INSERT
Just like their ABS counterparts these profiles should be used together. The procedure is exactly the same. The profile is usually used for printing in PLA of different colors, but can be used for other material mixes with minor tweaking. The example of the dual color medallion printed using this profile can be seen at the end of the video here http://www.youtube.com/watch?v=AEW-DNo0GxI.
How to print:
Slic3r

The Slic3r profiles include following...

Printer Settings: Note: Due to a bug in the v1.2.5 mod X2 of Slic3r the "double" and "mirror" profiles should be used for slicing in Slic3r plater UI. The plater UI can be brought up by pressing "S3rPlater" button in the Pronterface window (available if Slic3r is selected as your slicer). When the plater UI opens click "Add" or drag and drop the STL to the preview window. After the slicing is done click the "Export G-Code" button and when done exit the plater UI. The generated G-code will be loaded to Pronterface automatically.

How to Print
For the single extruder printing use x2v3 Printer Settings configuration. You can check and/or modify all the Slic3r slicing settings by going to "Settings->Slicing settings" from the Pronterface UI. The "File->Open" menu brings up the file selector dialog where an STL or G-code file can be picked. If the STL file is selected it is automatically sliced and the generated G-code is loaded. If a G-code (*.g) file is selected the G-code is loded as is. If you would like to use the dual extruder capabilities for printing support or infill in different material or color modify the "Multiple Extruders" configuration under the selected "Print Settings" profile.
Slic3r also allows to load multiple objects, chose what extruder to use for prinitng each of them and then slice them altogether. In order to use this Slic3r advanced dual extruder printing capability start the Slic3r Plater UI and do the following: The per-object settings are available when clicking on the "(+)" icon under the Extruder selection drop down box. After the slicing is done click the "Export G-Code" button and when done exit the plater UI. The generated G-code will be loaded to Pronterface automatically.
