#1  The 20W laser module can't cut through a 10mm basswood board due to its lens. What can I do?

Possible problem 1:  The lens on the copper cap of the laser module is dirty.

1. Why does it become dirty?

The 20W laser module works at high power. When used to process materials, it provides more energy, and thus a lot of smoke is generated. Therefore, the lens is easy to get dirty.
 

2. What can I do when the lens is dirty?

Use the xTool official maintenance pack or dust-free cloth with alcohol to clean the lens and nozzle on the laser module. If you use machine to process materials for a long time, it is recommended that you clean the lens and nozzle every hour.

You can use the following ways to keep the lens from getting dirty, and the effectiveness from high to low is described as follows:

  • Connect the laser module to an air pump

  • Connect the laser module to a nozzle and apply a sticker on the nozzle

To prevent the lens from getting dirty most effectively, it is recommended that you use an air pump.

Possible problem 2: The lens on the copper cap is damaged.

Solution: Replace the lens. The maintenance pack has provided one lens. If you need more, you can contact our after-sales services to purchase them.

Possible problem 3: Dust is accumulated on the nozzle.

Solution: Clean the nozzle. It is recommended that you use an air pump.

Possible problem 4: The nozzle is blocked, causing the laser beams to be reflected and damage the lens.

Solution: If you use the machine without an air pump, it is recommended that you apply the xTool official sticker or another sticker on the air inlet of the nozzle, or the dust is attached to the lens and accumulates around the laser beam outlet more easily, causing power attenuation, and thus affecting the processing performance.

 

#2  How to avoid rapid power decay due to dirty lenses and clogged nozzles.

1. Clean the laser module regularly

(1) Power off the machine, and remove the laser module from it.

(2) Remove the nozzle and nozzle connector from the laser module.

(3) Clean the inner and outer frames of the light shield with tissues or dust-free cloth moistened with alcohol.

(4) Use the xTool official maintenance pack or dust-free cloth with alcohol to clean the lens and nozzle on the laser module. If you use the machine in a very poor environment, such as one with much smoke and dust, it is recommended that you clean the lens and nozzle every hour.

 

2. Install the nozzle connector and insert the plug properly
