  • First off, your Default_Max_Feedrate for Z is way too high 4000 steps/rev , you have it at 10.
    #define DEFAULT_MAX_FEEDRATE          { 200, 200, 2, 25 }
    #define DEFAULT_MAX_ACCELERATION      { 2000, 2000, 100, 10000 }

    After changing these and uploading the new firmware settings, you must send the commands M502 followed by M500 to update the eeprom
