3D Software:
- OpenSCAD is a script-based 3D editor. it can make use of parameters, conditions, for and while loops, etc... This is currently Petaflot's choice
- http://www.3dtin.com/ Online in the browser
- http://www.netfabb.com/download.php (Linux version)
Printing software:
- http://slic3r.org/
- https://github.com/daid/Cura

The heater may be blocked inside
- Needs to be removed and cleaned
- Head may be replaced by the new one
Needs a new tube and fixation
One of the nozzle is loose. When the extrusion begins, the pipe move
- Nemen has printed a piece for fixin'

Software is kind of crappy

it's the only software worth it
Yes, you will need PyOpenGL for it to run. Displaying nice 3d images is not that trivial.

Recommended: Use the dev version on github: https://github.com/daid/Cura.git (12.10 when I'm writing)
Required packages: wxPython and PyOpenGL.
You can use a python virtualenv.

On first Cura start, you don't need to upgrade to Marlin firmware because it's already done.
You should run the checks, at least to check if USB connection between PC and the printer is working. For temperature check, the printer need to cool down (to ~30) before heating and check, it can take looong time.
Now you can use Cura to print objects.

Load a .stl model.
Change orientation, size, etc...
Click on the Prepare print button.
Software will slice the object into GCode. The more you choose a large scale object, the longer the execution time is.
When it done, click on Print button to open the Printing dialog.
Wait the software connect with the printer, Connection button will turn from clickable to readonly and Print button will turn from readonly to clickable.
Set the temperature with the arrows (yeah it's not working by putting the number directly)
Wait a bit so the hot end is distributively warmed
Extrude before printing, so the wire is at the start of the hot end
Make sure the wire is extruding correctly (the output wire is regular)
Click the Print button.
KEEP YOUR EYES ON THE PRINTER THROUGHOUT THE PRINTING PROCESS!!! And clean which could interfere the printing.

If a pile of plastic has formed in the extruder, remove the wire complitely and cut it
