Let’s dive into the essentials of keeping your laser lens spotless and your machine running like new.
Why Laser Lens Cleaning Matters for Your Desktop Laser Engraving Machine
The laser lens is the heart of your engraving machine’s precision. It focuses the beam that engraves your design onto materials. Over time, residue, dust, smoke, and micro-debris can accumulate on the lens, especially when engraving wood, acrylic, or leather.
Neglecting to clean your lens can result in:
-
Reduced engraving accuracy
-
Burn marks or haze on your material
-
Overheating or even laser failure
-
Costly replacements
To avoid performance issues and extend the life of your Monport Mega, consistent laser lens cleaning is crucial.
Recommended Cleaning Schedule
Monport suggests the following Monport Mega maintenance intervals based on machine usage:
-
After 24 hours of engraving: Perform a complete component cleaning.
-
After 4 hours of cutting: Clean the laser head and lens thoroughly.
Always ensure the machine is powered off and unplugged before beginning any maintenance.
Step-by-Step Laser Lens Cleaning Guide
Here is a detailed cleaning protocol to maintain your desktop laser engraving machine and protect its most vital component:
1. Disassembly of laser head housing
1) Remove the screws on the top cover and take off the top cover

2) Remove the screws on the side of the cover and slide it upwards to remove it.

2. Disassembly of Laser Head Components
1) Remove the air nozzle component of the laser head and place it properly on a static-dissipative and clean work surface.

2) Remove the focusing lens mounting base and clean the base with alcohol and a dust-free cloth.

Clean the stains on the laser head. (It is necessary to clean it daily to prevent blockage caused by prolonged use.)

3. Lens disassembly
1) Remove the silicone sealing gasket and the focusing lens assembly one by one. Pay attention to recording the disassembly sequence of each component.

4. Cleaning Operations
1) Clean the focusing lens using alcohol and a dust-free cloth.
2) Wipe the lens radially in a single direction (do not rotate while wiping).
3) Check the integrity of the lens surface and confirm there are no scratches or burn marks.
5. Assembly and Reset
1) Ensure that the convex surface of the focusing lens is facing upwards.
2) Install the sealing components in reverse order according to the original disassembly sequence.
Notes:
● Avoid touching the focusing mirror surface with bare hands.
● The working environment should be kept clean.
