9. Clean the mirrors above the laser nozzle assembly and the lens on the other side.
10. Reassemble the laser nozzle in reverse order, ensuring all components are securely fastened.
Cleaning the Machine Interior
1. Remove the front and rear screws of the cover.
2. Disconnect the LED light bar cable, door sensor cable, and push button cables.
3. Carefully remove the cover by pulling up. Use caution, as it's made of glass.
4. Repeat the process for the left side cover, removing the screws and disconnecting the cables.
5. Remove and vacuum the tray and honeycomb bed using the cordless vacuum with a brush attachment.
6. Remove the dust covers for the tube and electronics using Allen wrenches.
7. Vacuum all surfaces, including fans and hard-to-reach areas, using the brush and crevice attachments.

Cleaning and Lubricating the Rails
1. Use a cloth to thoroughly wipe down the X-axis rails on both sides.
2. Clean the recessed attachment points on the linear rails using Q-tips.
3. Wipe down the Z-axis rail and the linear bearings behind the laser head.
4. Clean the linear bearings underneath the gantry along the Y-axis.
5. Apply a thin layer of white lithium grease to all cleaned rails and bearings.
6. For the Z-axis screw, apply grease using a towel in an up-and-down motion.
Reassembly and Final Touches
