Marlin 2.1.1.1 build target LPC1768 pinmapping.h says: #define P2_04 0x44
I have this in configuration.adv:
#if TEMP_SENSOR_CHAMBER
#define TEMP_CHAMBER_PIN TEMP_1_PIN // #### Uses E1 thermistor input
#define HEATER_CHAMBER_PIN P2_04
The chamber temperature sensor works - the LCD allows me to set a target chamber temperature.
but the fan never starts.
There is no voltage on HE1 output marked 2.4 : [
github.com]
The fuses are ok.
I have never used HE1 before, so there is no reason to believe that the FET is defective.
I have also this, just enabled, and default PIDs and limits.:
#define PIDTEMPCHAMBER
//#define CHAMBER_LIMIT_SWITCHING
/**
* Max Chamber Power
* Applies to all forms of chamber control (PID, bang-bang, and bang-bang with hysteresis).
* When set to any value below 255, enables a form of PWM to the chamber heater that acts like a divider
* so don't use it unless you are OK with PWM on your heater. (See the comment on enabling PIDTEMPCHAMBER)
*/
#define MAX_CHAMBER_POWER 255 // limits duty cycle to chamber heater; 255=full current
#if ENABLED(PIDTEMPCHAMBER)
#define MIN_CHAMBER_POWER 0
//#define PID_CHAMBER_DEBUG // Print Chamber PID debug data to the serial port.

Additional info: the LCD clearly displays the chamber temp and allows to set target chamber temperature, but the Octorprint, for some reason, does not show anything about chamber-temperature, maybe comething is half-way configured?
