I just found that with the #define FAN_BOARD_PIN of 0.92.3, the fan is on when the bed is heating, but also when stepper motors are active. This near what I want for protect my card, even if the venti

Simplest solution currently would be either#define FAN_BOARD_PIN  pinnumber

//#define COMPAT_PRE1

#define PDM_FOR_COOLER 0

#define DEBUG_QUEUE_MOVE

(See Marlin,configuration.adv.h: #define ENDSTOPS_ONLY_FOR_HOMING // If defined the endstops will only be used for homing)

#define FEATURE_Z_PROBE 1

#define EXT0_TEMPSENSOR_TYPE 97

#define FAN_BOARD_PIN -1

hello AllI want to use termocupler for bed and I have AD595 board  I used ths board merlin firmware and ramps  connect aux1 A3 pin also change #define TEMP_1_PIN 3

* #define EXT0_TEMPSENSOR_TYPE 8

#define FEATURE_Z_PROBE 1

#define FEATURE_Z_PROBE 1

I have a home made Delta printer (Ardunio MEGA, Ramps 1.4) that was working well with .91. I could change the speed setting in Simplify3D and see the effect in the printer. This was after I upped the
