Can anyone help? axis Z

Can anyone help?
I am not be able to pitch Z
I’m a week trying to tune the z axis
Any tips?

Hi,

Could you be a little more specific?
Have you checked your threaded rod? Is it straight?
Have you installed some of the basic (and mandatory) modifications of the Z axis (motor mount and flex coupler) …

It’s all right in my rod z
and installed a component of cnc that is flexible allowing better quality.
estruder the bed and never get the correct distance. : s
