I've got an SKR 1.3 and the thermistor input for extruder 2 has gone bad.
In firmware, I've attempted to change the
TEMP_1_PIN to another in
pins_BTT_SKR.h and I've also defined
TEMP_1_PIN to another pin in
pins_BTT_SKR_V1_3.h but regardless of which pin I choose, the printer ignores it and still defaults to the dead input (
P0_25) I've made other changes in firmware to confirm that it is updating, but still - the second extruders temp input will not change.
Original code in pins_BTT_SKR.h
#ifndef TEMP_1_PIN #define TEMP_1_PIN P0_25_A2 // A2 (T2) - (69) - TEMP_1_PIN #endif
I've changed this to
#ifndef TEMP_1_PIN #define TEMP_1_PIN P1_28 // A2 (T2) - (69) - TEMP_1_PIN #endif
I've also commented out anything that referenced
P1_28 and added a
#define TEMP_1_PIN P1_28 in front of this and that didn't work either. I then moved that define to pins_BTT_SKR_V1_3.h and that still didn't work. It's still looking for a signal on
P0_25. I've also tried other available pins. It won't change. I must be missing something somewhere...
