// #define STEPPER_FREQUENCY 153000     // Maximum stepper frequency.

#define HOST_RESCUE 0

#define NUM_FANS 1

Probably so you are right, now I check the firmware and correct and test immediately. Do you know what the #define on configuration.h is?

#define Z_PROBE_TYPE 1          // 0 = no z probe, 1 = default z probe, 2 = Nozzle as probe

#define EXTRUDER_IS_Z_PROBE 1 --> so ist es eingestellt, verbaut ist ein kappazitiver Näherungsschalter mit diesen offsets, welche auch berücksichtigt werden:

#define EXTRUDER_IS_Z_PROBE 1

#define Z_PROBE_REPETITIONS 1

#define Z_PROBE_COATING 0

#define DISTORTION CORRECTION R from 100 to 90

So do I have to reduce these values? #define DISTORTION_XMIN 10 #define DISTORTION_YMIN 10 #define DISTORTION_XMAX 190 #define DISTORTION_YMAX 190 In this: #define DISTORTION_XMIN -90 #d

I can see gain but no bias. I still don't understand what I should put in #define TEMP_GAIN 0? 0 or 1?

#define Z_PROBE_SWITCHING_DISTANCE 5

In configure.h i edited #define TEMP_GAIN 20 (from 0). It is Ok?

On the old firmware #define EXT0_EXTRUDER_COOLER_PIN is set to 7 and if I'm not mistaken it should be wrong because the pin I use for the fan is 6, in fact even on start configuration string the coole

In configure.h i edited #define TEMP_GAIN 20 (from 0). It is Ok?

#define ZHOME_PRE_RAISE_DISTANCE 2

Regarding #define ENDSTOP_Z_BACK_ON_HOME 20 I correct it immediately as soon as I connect the printer.

Ok good luck. Make sure you have set #define ENDSTOP_Z_BACK_ON_HOME 20 or so so you are not directly at the end stops. With 0 at least one will stay there depending on the end stop offsets in eeprom.

#define SDSUPPORT 0 (dachte mann könne den SPI Bus für SD ausschalten oder entlasten..SD brauche ich nicht)
