Z axis Alignment
For the Vertex 251 - 312 and Excel 50X - 165X models.
Turn the machine off and disengage the Z brake. If the Z-axis is aligned properly the axis would slide down in Z when the machine is off and no brake is engaged, the operator should support the axis.
Push the stage using two hands to the top of the Z travel.
Loosen the two top screws that hold the Z drive assembly to the Z bearing plate and let it fall back to the bottom of the travel.
Retighten the top screws.
Push the Z-axis up using two hands and carefully test if the Z-axis slides down the drive screw. If it does not slide, then the axis is still misaligned.
If still misaligned, repeat step 1 and loosen the two back screws for the spacer between the Z drive assembly and the Z bearing plate.
