some issues after a long period without use of my printer (MendelMax II)

Hi all of you,
After a long period (more than 2 months) without using my printer, I decided to make a job and I encountered the following issues:
The displacement along X, Y and Z axes go to the wrong way.
I have corrected this, inverting the connectors on the board, but curiously, the end stop along Z axes works very curriously:
When I press "Z home", the nozzle goes up of 5 mm.
when I press simultaneously the "Z end stop" and the "Z home" buton, the nozzle goes donw and stops only when I release the "Z endstop" !

I have also loosed the bed temperature control.
I precise that the temperature sensor works perfectly, when I invert it on the board with the nozzle temperature sensor.

I have tryed to reload the Arduino 1.6.13 software but this time I get an error massage (see the atachment).

Thank you in advance for your help,
Best regards,
Jacques

Hi every body,
I must apologize, because I think I have send my question to early !
In fact, I just realized that you should not use Arduino if "Pronterface" is connected to the printer.
Neither should the LCD screen be connected!

At the moment, my printer can run again for the following reasons :
After having disconnected all the divices from my printer, my Mac excepted, I have reread the "Configuration h" and I have seen that the command of end stop Z was in a wrong state.
It was put :
"#define Z_MIN_ENDSTOP_INVERTING false //..."
I have replace this commad by:
"#define Z_MIN_ENDSTOP_INVERTING true //..."

The effect is that now the Z homing works normaly again.

Strengthened by this success, I have given a look to the temperature setings, and I discovered that the default seting of the bed sensor was :
"#define TEMP_SENSOR_BED 0"

while just above it was written :
"3 : Mendel-parts thermistor (4.7k pullup)"

so I have replace the
"#define TEMP_SENSOR_BED 0"
by
"#define TEMP_SENSOR_BED 3"

and it works now marvelously well.

Still pardon for the inconvenience!
Pearhaps my experience could serve to any body...
My best regards to all of you
