MKS 1.4 AD597 Thermocouples

I'm on the verge of getting this Printer going, still stuck on getting thermocouples working
repetier temps are both 499.5 deg. Error:MAXTEMP triggered, system stopped!
Is it because of the wrong pin setting on aux-1
5V GND D2
5V GND A3D57

Configuration.h
Thermal Settings -1 : thermocouple with AD595

#define TEMP_SENSOR_0 -1
#define TEMP_SENSOR_BED -1

pins.h

#ifndef TEMP_0_PIN
#define TEMP_0_PIN 3
#endif

#ifndef TEMP_BED_PIN
#define TEMP_BED_PIN 4
#endif

not sure what to do!

"5V GND D2" but yet firmware say #define TEMP_0_PIN 3

you cant use D anything you have to use the a ports, A3 and A4 on aux1

Please show picture of how you have it wired

I just reconnected thermocouples and reflashed the firmware with the same settings as my previous post.
The thermocouples connected are brand new and I have a green led on ad597

Have just noticed that if my power supply is unplugged the extruder/bed temps fluctuate around 486-490 deg
When powered on the temps are constant 499.5 deg.

Well the bed thermocouple (plugged into +5, gnd and d2) is not going to work... as it needs to be +5,gnd and A4, on the next row... It has to be a (A)nalog pin

So for now I would disable the bed thermocouple and remove that from d2 asap! (your feeding a analog voltage into a digital line)

I would just concentrate on the hot end for now.

Now there are various type of thermocouple, what did you get?
Its meant to be for a K -type Thermocouple

Okay removed D2 connector, It is a K-type Thermocouple 0-600° I uploaded a Clean marlin firmware 1.1.6 still the same issue.
