I just finished assembling and I connected the printer. I followed all the steps and connected the USB cable by selecting the COM port of the printer. I selected the tab "Arduino / Genuine Mega or Mega 2560" because I had no selection suggested by the instructions. Then I dragged the file and hit send on the tab "Configuration h" getting the following error:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
qr_solve.cpp:7:18: fatal error: time.h: No such file or directory

can someone help me?

Try to use arduino 1.0.1, it has the time.h library.

Thank you. Now go. I have to use the same version.
Can I change the language in some way or are there problems? I saw flags that show my tongue. If there were no conflicts would love to have it on display.
I am not at all clear is the initial adjustment. There are videos that show?
I do not understand how to assign the position 0 with the heads centered on the vertical axis. I do not understand how to adjust the maximum z and how to calibrate the probe axis x. Somehow I have to define a delta between the nozzle and the probe triggers when the switch so that it calculates the exact plan relative to the nozzle.

You can change the settings in language.h tab in the firmware, and re-install the firmware.
For the initial adjustment, you can see whether you can find it here:

I do not know what it's called the flag indicating why you cut the screenshot at the top where I could see where change but I do not know how to reinstall the firmware

You can find it in the tab language.h in your firmware. and refer to the link here to re-install the firmware:

I'm having a similar issue with my Prusa I3 X except that my error message is:

In file included from Marlin.ino:8:0:
C:\Users\Michael\Documents\Arduino\libraries\Marlin/dogm_font_data_marlin.h:12:25: fatal error: utility/u8g.h: No such file or directory

Error compiling.

You can refer to the information here:
For LCD12864
3.2.1 Check your arduino library folder, see if there is a library named U8glib. If not, download the marlin firmware and find the corresponding folder for your arduino version.
catalogue：\ArduinoAddons\Arduino_x.x.x\libraries
https://github.com/MarlinFirmware/Marlin
(refer to picture 1)
3.2.2 Restart your arduino and load the u8glib library：sketch>import library>u8glib
(refer to picture 2)
3.2.3 Reburn your firmware, and change the corresponding settings for LCD12864 in configuration.h tab.
Delete the “//” from "//#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER":
Change the codes :

// The RepRapDiscount FULL GRAPHIC SmartController (quadratic white PCB)
//http://reprap.org/wiki/RepRapDiscount_F ... Controller
//
// ==> REMEMBER TO INSTALL U8glib toyour ARDUINO library folder: http://code.google.com/p/u8glib/wiki/u8glib
//#defineREPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

to those ones:

// The RepRapDiscount FULL GRAPHIC SmartController (quadratic white PCB)
//http://reprap.org/wiki/RepRapDiscount_F ... Controller
//
// ==> REMEMBER TO INSTALL U8glib toyour ARDUINO library folder: http://code.google.com/p/u8glib/wiki/u8glib
#defineREPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

3.2.4 Choose the language, open ”language.h” in the firmware, find the following codes and choose the corresponding one for yourself.
