@matej1006
Do you use a magnetic bed?
I have the same problems with a 355x355 bed.

[matej1006]

@cando415
yeah from ziflex, realy and also like almost 1mm deviation

[CanDo415]

@matej1006
tyr the mapping cold and compare with a hot mapping. I think the differences are a problem of the magnethight

[matej1006]

@cando415 i did and there was not a lot of difference

[CanDo415]

@matej1006 so the temperature is not the problem

@cando415 if you have a straight edge you will be able to confirm quickly that its not the bed that is that warped. I think @jay_s_uk was right with the gantry.

@t3p3tony yeah i will just unscrew a little all screw in linear rail and then try.
Maybe i have ma linear rails in back more closer than in the front of printer.
i hope is that
