Wrong cut

[cncnescu]

I already checked the backslash and is max 0.03mm on all axis. When I cut a normal wood plate(acacia for ex) along the fiber I will get the right dimension and this I will get regardless of the fiber orientation of the wood plate if x along the fiber or y along the fiber. Against the fiber is always the wrong dimension.
In MDF bought dimension are more or less equal but bought wrong.

What are your steps per mm settings for x and y axis ?

I checked this at the beginning and it was fine...320 steps/ mm, 1600 micro steps on the stepper drive, 5mm / rev on the ballscrew.The same settings for all axis
