Hi!
I bought a reprap world thermocouple K type from E3D for my shiny new e3D hotend and hooked it up to my ramps board.
Unfortunately the temperature shown is 500°C, sometimes 499°C.
I think that I connected everything proper, the thermocouple V1.0 Board gets its 5V and GND, the analog pin I used is Pin 3 , as shown here:
http://reprap.org/wiki/ExtThermoCouple_1.0
Marlin-Wise i changed the following in configuration.h:
#define TEMP_SENSOR_0 -1
The problem MIGHT be on pins.h where I did not know where to put pin 3, since I found two places within the RAMPS section where
#define TEMP_0_PIN 3
is set...
#1: Could someone please tell me on which line in the current pins.h I should set #define TEMP_0_PIN ?
#2: Is it really pin 3 that is shown in the picture on the wiki link above? I heared that some ramps pins are not correctly numbered
#3: any other suggestions why this could happen?
Ah, the 500°C also get reported when I disconnect the thermocouple and the thermocouple board, so it seems to be a configuration fault.
Thanks!!
