firmware from the arduino project and updated #define MAX_JERK to 4.0, and changed acceleration as well  Again no change when I view the Jerk value or Acceleration values in the printer configuration

#define MOVE_X_WHEN_HOMED 0

#define MAXTEMP 275

#default_parameter_BED_TEMP: 60

#define FAN_PIN                                9

#define PID_CONTROL_RANGE 20

#define HAVE_HEATED_BED 0

#define PID_CONTROL_RANGE 20

In der Firmware ist der Punkt #define PID_PARAMS_PER_HOTEND auskommentiert. Vermutlich ein Flüchtigkeitsfehler. Ich hab mal die aktuelle 1.10 neu kompiliert und diesen Wert einkommentiert und es funkt

uncommenting this also had no effect //#define IGNORE_TMC5160_FEEDBACK

#define MIXING_EXTRUDER 1

#define NUM_EXTRUDER 3

#define ORIG_E0_STEP_PIN         26

#define EXT2_TEMPSENSOR_PIN TEMP_3_PIN ?

 #define EXT2_TEMPSENSOR_PIN TEMP_3_PIN                        ^

#define IGNORE_TMC2209_FEEDBACK

Right now, D10 will turn on and off with the m106 and m107 commands. I edited #define FEATURE_FAN2_CONTROL to be set to 1. This makes it so whatever FAN2_PIN is assigned, it will be controlled by M106

#define EXT0_ENABLE_PIN ORIG_E0_ENABLE_PIN

#define EXT0_ENABLE_PIN ORIG_E0_ENABLE_PIN
