Issue description

When the focus lens holder is uninstalled, the screw on the holder is stripped.

Possible causes

1. The way of uninstalling the focus lens holder is incorrect.
2. The screw is tightened too much.

Troubleshooting procedures

1. Tighten the screw in the correct direction

Directly face the laser module. Loosen the screw anticlockwise, while tightening the screw clockwise.

2. Use a correct screwdriver

Use the Phillips screwdriver included in the package or a Phillips screwdriver of the same specification to loosen the screw.

3. Remove the holder base

If the screw is stripped severely, follow the steps to remove the holder base.

(1) Remove the laser module's cover. Use a slot-type screwdriver to lower the Z-axis motor shaft to the lowest position.

(2) Use a 2.5mm hex key to remove 4 screws on the back of the holder base.

(3) Take out the holder base, then follow the following steps.

4. Increase the friction

Apply an ultrathin rubber sheet or foil sheet between the stripped screw and screwdriver to increase friction. Then, loosen the screw.

5. Apply lubricating oil

Apply a small amount of lubricating oil to the gap of the stripped screw, such as WD-40. Wait for a few minutes, and loosen the screw.

6. Replace the whole components

Contact xTool after-sales service, and ask for replacing the holder base components (including the focus lens, focus lens holder, holder base, but excluding the nozzle ).
