Zhangxueyou gave a wrong item, Sanguinololu cannot support a dual extruder.

I saw your pictures and now I have a question, do you mean you pluged a same thermistor into the bed thermistor slot and hotend thermistor to measure the temperature, but you got 2 different values, one is 18 degree and the other is 140 degree? I only want to know that can you get right value from ...

I sent a m119 through repetier host for each endstop. They all showed open. Then i would hold each endstop down and sent another m119 each time and they would show triggered for the one i pressed. That rules out the end stops. I have updated the firmware, no luck. I have swapped around the steppers ...

Please adjust the screw next to the filament hole, it makes the pressure between wheel and filament to be tight or loose.
Sometimes a high temperature is useful.

Did your LCD display right before, even once? How about it when you first used it? We need to confirm it's a software or a hardware issue.

The logic level in endstop is inverse, so it always get a inverse signal which is not expected. There is a simple way to know it's right or wrong. Press the endstop and then home axis, if the axis move in right direction, it means the endstop's logic level is wrong. You had better check X axis ...

dose it move only a little bit? If it's, pls press the endstop and move it again, i guess the endstop signal is missing or get a inverse level.

Could you take a photo for the part you printed and paste it here? It will be helpful.

You don't need to re-upload a firmware, we had uploaded a Marlin firmware for your machine.
Can you home all axis when clicking on HOME button?
Visit the wiki page for your motherboard and it will show you how to connect a LCD screen.

Yes, you are right.
