    seems like you have the z steps/mm set wrong in your firmware
     What type Z rods are fitted? M5 threaded rods, M8 threaded rods or M8 4 start lead screws ?
  • danirodaniro
    M8 THREADED RODS, DEFUALT STEPS ARE 2560 STEPS/mm
  • MartinHMartinH
    And what controller board ?
  • danirodaniro
    solved, changed the steps of z to 426.67.

  • danirodaniro
    control board SANUINOLOLU 4A4998
  • MartinHMartinH
    426 is more a 4 start lead screw size
    make sure you have the 3 jumpers installed under each 4998 driver pcb to set 1/16 microsteping.
