THANKS FOR YOUR HELP

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 ?

M8 THREADED RODS, DEFUALT STEPS ARE 2560 STEPS/mm

And what controller board ?

solved, changed the steps of z to 426.67.

control board SANUINOLOLU 4A4998

<font face="Arial, Verdana">426 is more a 4 start lead screw size</font>

make sure you have the 3 jumpers installed under each 4998 driver pcb to set 1/16 microsteping.
