If you want greater control over the mesh process you can create a macro called mesh.g and place it in the system tab. Inside that macro you can set the jerk and acceleration limits you wish for the Z axis and setup M558 however you like and then call G29 S0 to start the mesh creation. Then you can reset the z axis values back to whatever you want for normal operation.
To call mesh.g send G29 to start the process.
