In the Nano Duo, the metal plate in the middle is designed to be thin to allow the L-shaped support frame to fit tightly against the column. However, the thin metal plate is prone to creasing when subjected to external pressure.
If the metal plate is creased, it can be replaced by following these steps:

1. Rotate the hand-tightening nut counterclockwise to remove the L-shaped support frame.

2. Use a hex wrench to remove the 4 screws shown in the figure and take off the toothed connector.

3. Remove the positioning pieces at the top and bottom of the column and take out the damaged metal plate.

4. Place the new metal plate in position and reinstall the positioning pieces at the top and bottom of the column as shown in the figure.

5. Use the hex wrench to tighten the screws to secure the toothed connector, then reinstall the L-shaped support frame. The metal plate replacement is now complete.

If wavy traces appear during border tracing, this issue is caused by the old firmware. You can resolve it by updating the firmware.

Step-by-step instructions:

1. Download the latest firmware from the official website and save it to the SD card.
Turn on the machine and insert the SD card into the slot on the side of the machine. When an upward arrow and the word “SD” appear on the main interface, it means the file has been successfully read.

2. On the main interface, tap the “Settings” option to enter the settings screen, which includes basic settings such as network, language, etc.

3. Tap the “Firmware update” option to enter the upgrade screen, then tap the upward arrow button to start the component upgrade.

4. “Screen” represents the screen component upgrade, “Galvo” represents the galvo component upgrade, and “Main Control” represents the main control component upgrade. Select the component you want to upgrade to proceed.

Note: When there are no new firmware components on the SD card, the screen will display “Retrieval failed.”

Nano DUO is equipped with a built-in screen that allows for basic operations. The steps to switch between red and blue laser engraving are as follows:

1. Tap File scanning and select the desired engraving file.
Note: Make sure the SD card is inserted into the slot.

2. In Light Source, tap the dropdown menu and select:
450 nm [Blue Laser] or 1064nm [Infrared Laser]

Note: Only files generated by LightBurn and LaserGRBL support red and blue laser switching. Since LaserBurn integrates commands that enable simultaneous dual-laser engraving into the *.gc file, the light source cannot be changed through the screen.

1. LightBurn
After successfully connecting to Nano DUO, enter the following commands in the console input box and press Enter to send:
$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

2. LaserGRBL
After successfully connecting to Nano DUO, enter the following commands in the console input box and press Enter to send:
$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

3. LaserBurn PC

On the control page, click Engraving, and you can directly control the LED light using the LED Light button.

As shown in the right image below, click the top menu button, enter the command in the input window, and click Send to send:
$nano/led=off 【Turn off LED】
$nano/led=on 【Turn on LED】

Nano DUO is a high-speed engraving machine, and sometimes engraving lag may occur when the data transmission speed is slower than the engraving speed. To prevent lag, you can apply the following settings:
Note: Engraving via SD card will not experience lag.

1. LightBurn
Click the button in the top menu bar, enable the Enable GCode Clustering option, and click OK.

2. LaserBurn PC
Click the button in the top menu bar to open the Machine Settings interface, enable the Enable GCode Clustering option, and click Save.

During engraving, if the machine suddenly stops, it is mainly caused by the following two reasons:

1. Data Loss
If connected via a data cable, a loose port or a damaged cable may cause the port to disconnect. Please replace the data cable.

2. Machine Alarm
During engraving, if the machine experiences shaking or tilting, an alarm will trigger, the red light will turn on, and engraving will stop. Once the alarm is cleared, engraving can resume normally.
If the alarm does not automatically clear, connect the machine to a computer, open LightBurn or LaserBurn software, and enter $X in the console to clear the alarm.

Troubleshooting:

1. Network
Check whether the Nano Duo and the computer are on the same network. If they are not on the same network, IP connection will not be possible. Network settings can be configured via the machine’s screen or the mobile app.

2. Machine Occupancy
Check whether the Nano Duo is already connected via IP to another device or software. The Nano Duo only supports one device/software connected via IP at a time.

Follow these steps to clean the laser window lens and galvo mirror:

1. Prepare alcohol and a lint-free cloth.

2. Rotate counterclockwise to remove the laser window lens. The galvo mirror and the laser window lens are shown below.

3.Moisten the lint-free cloth with alcohol and gently wipe the front and back surfaces of both the galvo mirror and the laser window lens. Make sure to dry off any alcohol completely to avoid watermarks.

4.After cleaning, reinstall the laser window lens by rotating it clockwise back into place.

To lubricate and maintain the moving parts, follow these steps:

Remove the L-shaped support bracket

Turn the hand-tightened nut counterclockwise to remove the L-shaped support bracket.

Remove the column housing

1. Use a hex wrench to remove the 12 screws on the inner and outer sides of the column.

2. Remove the positioning plate and column cover to take out the column housing.

Remove the slider screws

1. Use a hex wrench to remove the 8 screws at the front and back that fix the slider in place.

Apply lubricant to the guide rails

1. Push the slider to one end of the guide rail.

2. Use a brush to apply lubricating oil to the contact surfaces of the guide rail.

3. Push the slider to the other end and apply oil again, ensuring an even distribution of lubricant along the contact surfaces.

Reassemble and clean

1. Wipe off any excess lubricant around the guide rails.

2. Refix the slider with screws.

3. Reinstall the column housing, positioning plate, column cover, and L-shaped support bracket in order.

The lubrication and maintenance of the moving parts are now complete.

To replace the coupling, follow these steps:

Remove the L-shaped support bracket

1. Turn the hand-tightened nut counterclockwise to remove the L-shaped support bracket.

Remove the column housing

1. Use a hex wrench to remove the 12 screws on the inner and outer sides of the column.

2. Remove the positioning plate and column cover to take out the column housing.

Remove the old coupling

1. Use a hex wrench to remove the 2 screws fixing the coupling and the 8 screws at the front and back of the slider.

2. Once the connected moving parts are loosened, the coupling can be removed.

Install the new coupling

1. Place the new coupling in its original position.

2. Use screws to secure the coupling to the slider.

Reassemble the column housing

Place the column housing, positioning plate, and column cover back in order and secure them with screws using a hex wrench.

Reinstall the L-shaped support bracket
