I have big problem with Z i don’t want put negative values on position\_min because i have a mesh of the bed! Can any one help me?

Use position\_min: -3 . Your bed mesh is falling below Z=0 and that’s why you get “out of range”. ---

Bed mesh is not a virtual bed? Why the machine don’t change 0 of Z next move to XY coordinates of mesh bed? Negative position\_min is not dangerous? mesh is useless ? ---

Mesh is just a map of hills and valleys. Some valleys are under 0 because you bed isn’t perfectly flat. Negative position is not dangerous as long as you don’t try deliberate to move your Z under 0 but it’s necessary as a buffer for mesh. ---

No, not possible. You need some head-room for the mesh also in the negative direction. How much depends on the quality of your bed and the respective deviations of the mesh. ---

Thank you, a lot of people and guides they explain the negative value on only for testing and next you need put only 0 because is dangerous have negative value! I thought why are another way for work.
