LED8 on Arduino blinking red?

Recommended Posts

Does anyone know if I should be worried when LED8 on the Arduino board is blinking red when printing?

 

I just happened to notice this and I'm not sure if something is wrong or not. Usually red flashing lights are no good... The printer seems to printing alright though.

Should I be worried, or did it always blink when heating, and I just never noticed before?
