How to Replace the Z-Axis Metal Plate on Nano Duo

In the Nano Duo, the metal plate in the middle is designed to be thin to allow the L-shaped support frame to fit tightly against the column. However, the thin metal plate is prone to creasing when subjected to external pressure.
If the metal plate is creased, it can be replaced by following these steps:

1. Rotate the hand-tightening nut counterclockwise to remove the L-shaped support frame.

2. Use a hex wrench to remove the 4 screws shown in the figure and take off the toothed connector.

3. Remove the positioning pieces at the top and bottom of the column and take out the damaged metal plate.

4. Place the new metal plate in position and reinstall the positioning pieces at the top and bottom of the column as shown in the figure.

5. Use the hex wrench to tighten the screws to secure the toothed connector, then reinstall the L-shaped support frame. The metal plate replacement is now complete.
