3d printer

Issue to fix

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 begin, the pipe will move.
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.
Click the Print button.
KEEP YOUR EYES ON THE PRINTER THROUGHOUT THE PRINTING PROCESS!!! And clean which could interfere the printing.
