Need help with sanguino (2 replies)

Hi everyone

I've got a pusa i3 with sanguino board. Suddenly while i was printing the printer stopped and showed on lcd screen error maxtemp at extruder's thermistor. I changed thermistor, i tried to re upload the firmware but that issue continued to appear. Finally i replaced sanguino with an arduino mega plus ramps 1.4 and worked fine. Is there a solution to fix sanguino or is it dead ?

thanks in advance
