1.Please describe more specific: What is the first line and 4th line of LCD displaying? I think thermistor is not well connected, but I am not sure which one.
2. Please check if the connection of endstops are correct.

3. Y axis' moving direction can be changed in firmware. Do you have firmware? If not, please leave your email address, I can send you the firmware.
4. The extruder motor can not move unless the temperature of extruder is more than 180 degrees.

I can not see any file in Arduino1.0.1. You should drag all the files of firmware into Arduino.

Ok I understand now. Now issue 2 and 3 are correctly solved.

Thank you very much
