Hi-- As soon as I turn my printer on (Prusa Mendel) the LED4 light immediately turns on and the Hot End starts heating up indefinitely. It's as though it was given a command to heat up and it can't reach the requested temperate but it keeps trying. I've turned it off and on multiple times, and I've tried pressing both reset buttons on the RAMPs board and underneath on the Arduino, but to no avail.
Is there any way to get it to stop a command and reset entirely?
