Extruded motor not turning

[Diemonik]

I used the firmware you sent and now nothing works , the lcd makes a beep loud noise and doesnot display anything ,I had to unplug the lcd to make it stop... now the printer does not work .. what now ??

The LCD makes noisy beep because you connect the cables wrong. The slot beside the SD card is connected to "SD Card" on mainboard.
And so far, you have not told me if you have check if the extruder motor driver is fine by swapping with other motor driver.

Lcd was working before I added the firmware , and I had swap the motor and it work if I plug it in x or y , just in the extruder area none of the 2 extruder motor move , but if I plug them else where they work...

Is the motor driver (we sent A4988 usually) fine? You can check it by swapping it with x motor driver.
