Recommended Frequency
Once every 1-2 weeks, depending on the frequency of usage and material
Maintenance Steps
If the engraving material is paper or wood, it is more likely to cause dust and tar oil to stick to the reflective mirrors. You can use cotton swabs with a small amount of alcohol to clean and wipe until the mirror surface is stain-free.
Preparation Items
Cotton swab, 75%~99% alcohol
There are three reflective mirrors, one focus lens, and one laser tube output lens that need to be cleaned in Beambox II, and their positions are shown in the picture.
Maintenance Steps
1. Clean the laser tube output lens
The laser tube output lens is located on the low-pressure side of the laser tube (close to the 1st mirror). You can open the back cover and wipe it, as shown below.
2. Clean the first reflective mirror and beam combiners
The first reflective mirror and beam combiners are located on the low-pressure side of the laser tube facing the chassis. You can open the back cover to clean the beam combiners and the first reflective mirror.
Alternatively, you can wipe the first reflective mirror from the front opening, as shown below.
3. Clean the second reflective mirror
The second reflective mirror is located on the left Y-axis guiding rod.
4. Clean the third reflective mirror
The third reflective mirror is in the triangular mirror holder on the X-axis linear rail.
5. Clean the focus lens
The focus lens is under the third reflective mirror inside the laser head.
a. Lower the platform
b. Put the material in the center of the bed to prevent the lens from falling.
c. Remove the focus lens.
d. Take out the focus lens and then clean it.
6. Put the focus lens back
The focus lens is under the third reflective mirror inside the laser head.
