Help needed with thermistor issue: reconfiguring pins
March 05, 2014 09:02PM
Hello,

I recently ran into an issue where my T0 thermister (for hot end) was either reading 499 or 0. Switching heat bed and hot end thermister connections confirmed the problem was with the connection to T) as opposed to the actual thermistors. I've read on the forum posts for simmilar issues that the pin configuration can be changed so that I can just reconfigure the pins.h in Marlin so that My T1 connection would serve as my T0 by switching its setting to 15.
This is all well and good but I am in the dark as to how to make the T2 connection my new T1.

Working with Motherboard setup 33
the pins.h section I need to mess with is as follows:
#define TEMP_0_PIN 13 // ANALOG NUMBERING
#define TEMP_1_PIN 15 // ANALOG NUMBERING
#define TEMP_2_PIN -1 // ANALOG NUMBERING

Any help would be greatly appreciated

TEMP_0_PIN should be your current hot end thermistor input, which is now set to pin 13. This pin is what has (apparently) died. TEMP_1_PIN should be your heated bed thermistor input, leave this alone. You should be able to use the pin that is currently attached to T2 as your hot end thermistor input. Try setting TEMP_0_PIN to 14, which should be the pin connected to T2. Then you can plug your hot end thermistor into T2 instead of T0.
