    I just loaded up my printer and tried to test the x axis and then it happened. It blinked orange and stopped working. I then restarted and it turned on as usual but then did the same thing. Any tips

    update: it only appears to happen when an end stop is hit, but why?

    The LEDS are not always consistent, look at the board layout and be specific which LEDs are on.
    Normally there is an LED (red) for the MOSFET on D9 so that light is on when the MOSFET has power. Your board may be different or you may be talking about a different LED.



    (the one for D10 is often yellow for example, but sometimes RED)

    If you can't tell which LED it is, use a picture or the schematic to call it out so we know which ones you mean.

    I think this may be due to the arduino over heating, any tips?

    Well, if you think the Arduino is bad, replace it. I don't have any suggestions for troubleshooting it.
    That will require you to reload the firmware after you replace it.

    LED1 is connected to D13, so is firmware controlled (D13 is the Arduino "test LED" and is used for indicating RAMPS ENABLED)
    LED2 is on when D8 is on
    LED3 is on when D9 is on
    LED4 is on when D10 is on

    So your LED is normal (except when it turns off)

    Check your endstops and per the connection picture above make sure you do not have them jumped from - to + rather than from - to S
    Some RAMPS boards have all 3 pins populated and the same style and it is easy to put an endstop across the -/+ rather then across -/S and if you do it wrong then when the endstop triggers it is shorting the power supply.
