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!

Hi, all sorted with steppers but now will not read sd card! Any ideas please.
Ron

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

where can I buy stepper driver chips for gt2560 board?
