On the start Gcode you must have The command G29 after the G28 command to enable autoleveling process.
For the Z offset you must adjust with the Gcode on the termininal
M851 'Show the current offset on EEPROM
M851 Z-1.0 'SET the offset to 1mm (Value to be adapted) if you increase th value ex Z-1.2 the nozzle will be close the bed
Dont forget to do M500 after to store the value on EEPROM.
