Hi, the control board on my i3 pro b stopped working so I have fitted a new gt2560 rev a board. I have Arduino 1.0.1 on my laptop and uploaded marlin firmware but there is no response from any steppers and I don't think it is getting up to temperature even though the lcd indicates it is. I can't purge any filament at 215 degrees. The nozzle is not blocked! It will respond to temp setting in Repetier but still no stepper movement. Am I missing something!

To make things clear, it will read existing files already on my card but not newly added ones. Why?
