I Will try ,but now i make an experiment and i found the problem. The problem Is that when It do G28 and G29 (when it Is printing) It work fine but at the end the extruder go up and print on air ,(and It say Z 0,15 mm) . What Is the problem? If i take off all G28 and G 29 commands ,and I do manually It work…I understand! When i do manually i need to do G1 Z0 because if i don’t do that command It will print at the last height even if the height Is more than normal .The problem Is that the printer don’t save the Z axis height .

You will need to do exactly like in the link above, an adjust the z value until its perfect. Ps my z offset is 1.5, put this value and observe the modification. If you do not succed contact me. Let me know if you succed
