1000 Thanks ......

I wanted to be sure before doing anything.
Now I just have some works to solder and preprare the card as you show it in your "How to".

Download this file, its the soon-to-be-released Arduino 1.05 version:

Select File->Examples->SolidoodleMarlin , set the correct Motherboard value to 33 or 34 in Configuration.h, set the Solidoodle to the right model (2/3), Select the RAMPS comport under Tools->Serial, and choose Arduino Mega 2560 under the Tools->Board menu.

Compile, Upload, done.

I have this card :

It have a: Atmega 2560 (Arduino compatible)

A force de lire plein de thread différent j'arrive à me perdre mais j'ai bon espoir d'aller jusqu'au bout, si j''y arrive je ferais surement un tuto en français .

there is another think to change if i remember, it's the connection of the 3 endstops ..

Just another question, the power unit ,sold with the SD2,  is enough powerfull for th ramps or do I have to buy something more powerfull ?

answer 1 : 

[1]You can use the same firmware, you just select option // 33 = RAMPS 1.3 / 1.4 (Power outputs: Extruder, Bed, Fan) /  when setting up the marlin firmware. You do this by changing line 54:

When you say the same firmware  do you mean the firmware that is already in the ramps 1,4 when you buy it ?
How to change those line ?   in repetier host or in the arduino software ?

answer 2 :

[2]You install it on the board the same way as the SD Motherboard.

Thanks for the explanation I never had to modify or to change the firmware of the SD board so I was unable to know how to use Arduino software(you can change some settings(filament multiplier and PID for the hot end) in the eeprom with repetier host ).

answer 3: Ok I already know how to do it so !

I've read the how to for the ramps 1,4 on the forum but I must admiot I did not understood all.

[1]Where to find the firmaware ?
[2]How to install it on the board ?

[3]How to put parameters in repetier(is it the same as for the SD motherboard ?)

[4]PS: I would also thanks LAWSY for all the things he's making for us  !!!

[1]You can use the same firmware, you just select option // 33 = RAMPS 1.3 / 1.4 (Power outputs: Extruder, Bed, Fan) /  when setting up the marlin firmware. You do this by changing line 54:

#define MOTHERBOARD 62 //{SD Patch}

to

#define MOTHERBOARD 33

[2]You install it on the board the same way as the SD Motherboard.
[*]Download and install Arduino 1.0.5 or >[/*]
[*]Download the latest marlin for solidoodle firmware from Lawys or Adrians github (search forums for address)[/*]
[*]Open marlin firmware in arduino and set options in Configuration.h (be sure to change #define SOLIDOODLE_VERSION 2 to 3 if you have a SD3) [/*]
[*]Choose your board type in Arduino by going to the tools > board menu[/*]
[*] Select your com port [/*]
[*]Compile and Upload[/*]

[3] Same way as stock board

[4]Ditto
