Hi all i haven been working with my printer for a few months du to renovation did turn it on a bit a go but never got in to my problem the hot end just heats up no mater what even on 5v usb power it still heats up tryed reuploading marlin and still nothing any sugestions thanks

Is the temp working good?

Ya but it dus not stop just keeps climing

// The minimal temperature defines the temperature below which the heater will not be enabled It is used
// to check that the wiring to the thermistor is not broken.
// Otherwise this would lead to the heater being powered on all the time.
#define HEATER_0_MINTEMP 5
#define HEATER_1_MINTEMP 5
#define HEATER_2_MINTEMP 5
#define BED_MINTEMP 5

Check this part of your firmware setting, might have the wrong numbers.

Would it still show the temp on the screen if that hapend

Ok i just tuck my board out of myvprinter and found this its a burned out part of the in the thermister the whered thing that is that tue temp still shows on my lcd and sugestions on a fix or patch

Just follow to next solder spot and solder a cable with 2 pin terminals on the other end, cut the copper trace to prevent further shortages.
