6.1 Maintenance Schedule

This maintenance schedule is for reference only. Should you use the laser engraving and cutting machine more frequently, adjust your schedule according to your usage frequency. Before maintenance, check Snapmaker’s Limited Warranty so as not to void your warranty.

 Turn off the power supply before maintenance.

• Daily

• Every Month

• Every Three Months

6.2 Daily

6.2.1 Check the Cables

Check if every cable is plugged into the right socket, in the right direction.

• On the Controller

(A350/A250)

(A150)

• On the Converters

Snapmaker 2.0 A150 has no Converters.

• On the Laser Module

6.2.2 Check the Support Platform

Check if the Support Platform is assembled in the correct direction. The front without screws should face up, and the rear with some screws faces down. The reversely installed platform will be higher than the correctly installed one.

Check if the Support Platform is flat and stable, fully tightened with screws. If not, loosen all screws and reassemble the platform.

6.2.3 Check the Laser Engraving and Cutting Platform

• Check the Laser Engraving and Cutting Platform

Check if the Laser Engraving and Cutting Platform is flat and stable, and fully tightened with screws. If not, reassemble the Laser Engraving and Cutting Platform.

• Clean the Laser Engraving and Cutting Platform

Dust and debris accumulated on the Laser Engraving and Cutting Platform not only make it difficult to fasten materials on the platform, but also pose a fire hazard.

To avoid this, you should check if the Laser Engraving and Cutting Platform is clean. If not, use a stiff brush or vacuum to clean it. You can also take down the platform for cleaning and install it back to place after.

6.2.4 Check the Built-in Fan

The Laser Module uses a built-in fan to dissipate heat as well as prevent dust accumulation on the laser lens. If the built-in fan does not work normally, the laser inside the Laser Module may become overheated and prone to damage.

To avoid this, take the following steps to check the built-in fan each time before you use the laser engraving and cutting machine:

(1) Put on the Laser Safety Goggles.
(2) On the Touchscreen, swipe left to select Control.
(3) Tap Laser Power. Adjust the laser power to the lowest value, and turn on the laser.
(4) Put the end of a strip of paper or a soft feather under the lens hood, as shown in the pictures. Be careful not to expose your body parts directly under the laser beam.

(5) If the paper or feather is moving with the flow that comes out of the lens hood, it indicates that the built-in fan is working. If the paper or feather is sucked into the lens hood or air flow cannot be detected at the mouth of the lens hood, the built-in fan may be stuck or broken. Maintenance or replacement by professional personnel is required.

6.2.5 Check the Camera and the Camera Light

Check if the camera captures a clear image. A blurry image may be caused by dust accumulation on the camera lens or week light. If the image is not clear, clean the camera lens and the camera light with a piece of soft cloth. Also, due to the qualities of polycarbonate which is used to synthesize the lens, you should use PH neutral detergent or water to clean the lens and avoid scraping it.

If the light is still week, the camera light may be broken. Maintenance or replacement by professional personnel is required. If the light is bright, but the camera capture image is still blurry, the camera may be broken. Maintenance or replacement by professional personnel is required.

6.3 Every Month

6.3.1 Clean the Linear Modules

Keeping all Linear Modules free of dust and foreign matters helps reduce friction and noise while the Laser Module is moving. To do so, gently wipe the Linear Module surface using a piece of dry cotton cloth.

While cleaning, do not press the steel strip.

Do not dismantle the Linear Modules yourself, as doing it will void your Snapmaker’s Limited Warranty.

If the steel strip comes loose, contact us at support@snapmaker.com.

6.3.2 Clean the Side Covers

The Laser Module has two side covers, each with a vent and dust-proof net for heat dissipation for the fan inside the Module. If blocked by dust, the nets will prevent the vent from functioning. Failure to cooling down the internal components will cause the Module to malfunction.

To avoid this, you should check the vents and dust-proof nets monthly. Use a brush, swab, or vacuum to clean the dust on the vents and nets.

6.3.3 Check the Exhaust System

If you use an exhaust system, always inspect the exhaust fan and duct work for obstructions and ensure proper air flow before each use. Unobstructed and properly maintained exhaust fan and duct work will reduce the risk of fire and extract caustic fumes and smoke. Check the following parts before each use:

• Fans

Dust and debris can easily accumulate on the exhaust fans and make the fans stuck. Clean the fans each month to ensure that they work properly.

• Filters

If you use an air purifier, follow its user manual. Replace the filter when its life is running low. The inside of the filter may be filled with poisonous chemicals, so do not try to take apart and wash it.

6.4 Every Three Months

To keep your laser engraving and cutting machine and Luban up to date, update your firmware and software every three months.
