Cleaning and Maintenance of Laser Module for xTool M2
Video tutorial
Clean the lens protector and nozzle
Laser processing often produces a large amount of smoke, which may cause the lens protector to get dirty or block the nozzle. If they are not cleaned in a timely manner, the laser power may reduce, and the laser module may be damaged.
- Avoid scratches: The surface of the lens protector is fragile and may easily get scratched. When installing, replacing, or cleaning the lens protector, be very careful and avoid sharp objects contacting the protector.
- Working environment: Poor environmental conditions may accelerate the aging and damage of the lens protector. Therefore, keep the inside of the device dry, free of dust and corrosive gases, and ensure that the exhaust fan works properly.
- Regular check: Regularly check whether the lens protector is installed firmly in place. If it is loose or displaced, adjust and fix it promptly.
- Regular cleaning: The lens protector may accumulate dust, dirt, or other impurities that reduce the laser transmission rate. You need to clean it regularly.
- Regular replacement: An overly worn lens protector may reduce the transmission rate of the laser or even cause device faults. You need to replace it regularly based on the use of the device and the wear of the lens protector.
Tools required
- Hex screwdriver
- Lint-free cloth or a cotton swab
- Ethyl alcohol
Cleaning steps
⚠️ When performing the maintenance, please turn off the device and unplug the power cable.
When the software prompts a cleaning reminder, follow the steps to clean the lens protector and nozzle.
(1) Remove the laser module from the device.
(2) Remove the nozzle from the laser module.
(3) Use a lint-free cloth or a cotton swab moistened with ethyl alcohol to clean the lens protector and nozzle in order.
💡 With the air assist set, you can clean the laser module at a lower frequency.
Clean the exhaust fan
Cleaning the exhaust fan can:
- Prevent overheating and protect the laser module. During processing, the laser module generates a large amount of heat. The fan assists in dissipating the heat, maintaining the laser module's operating temperature within a safe range. If the fan accumulates excessive dust or is clogged, it leads to a decrease in heat dissipation efficiency, and the laser module may be damaged due to overheating.
- Prevent electrical malfunctions or fire risks. Dust accumulation not only affects heat dissipation but also increases the risk of electrical failures or short circuits, particularly in high-temperature environments. Cleaning the fan reduces dust accumulation, decreases the potential risks, and ensures safe device operation.

Cleaning steps
• Ensure that you disconnect the cable from the main control board during cleaning. Avoid using excessively wet towels, as excessive moisture may seep into the device and cause a short circuit in the electrical circuit, which may damage the laser's main control board.
• Make sure to reconnect the cable securely after cleaning and avoid pulling the cable with excessive force.
(1) Turn off the device, disconnect the power supply, and remove the laser module.
(2) Remove the screws, and remove the exhaust fan from the laser module.
(3) Use a lint-free cloth or a cotton swab moistened with clean water or ethyl alcohol to clean the fan.
