1. Only operate the printer as described in the manual to avoid personal injury and damage to property.
2. The standard input voltage of the printer is 230 V. If the local voltage is 115 V, ensure that you switch the input voltage before commissioning the printer.
3. The assembly videos, the configuration file and the cutting software are contained on the U-disc, please save the files on the U-disc to your computer before use.
4. Do not place the printer near flammable, explosive or high heat sources, make sure that the printer is in a safe and stable printing environment.
5. When the printer is in operation, do not touch the parts with high temperature, such as the hot print bed and the nozzle, to avoid burns caused by high temperatures.
6. Children and untrained personnel must not use the printer alone.
7. It is recommended to use the filament recommended by the manufacturer, which can not only reduce nozzle clogging but also ensure print quality.
8. To ensure the service life of the printer, regular maintenance of the printer, in particular the effector module and the cable rail as well as other important parts, is required.
9. In the event of an emergency during printing, please click the emergency stop button on the screen or switch off the power directly.
10. If you are not using the printer for a longer period of time, please disconnect the power cable to ensure safe use of the power.
11. The Flsun V400 does not use configuration files from other printers for cutting in order to avoid unpredictable situations.
12. The printer was installed and tested before leaving the factory. It is normal if the printer has been used.

The standard input voltage of the printer is 230 V. Please ensure that the printer is set to your local voltage before switching on the power switch for the first time.

If the local voltage is 115V, move the red switch to the right to change the input voltage to 115V.

1. Click on "Settings>Print bed levelling>Height adjustment>Continue", please confirm that you are using the levelling module before levelling. After completing the first levelling, the printer will restart and display the homepage. The data will be saved automatically.
2. Then click on "Settings>Levelling pressure bed>Bed>Continue" for the bed grid, the data will be saved automatically.
3. Remove the levelling switch and disconnect the connection after you have levelled the bed net and click on "Settings>Levelling print bed>Move ZO>Continue".
4. Take a piece of A4 paper and place it under the nozzle, click on "Z-calibration" and use "Z+" or "Z-" to set the height of the nozzle. As soon as the sheet can be pulled away with slight resistance, the optimum distance has been reached. Now you can click on the "Back" button and then press the "Home" button.

After replacing the different filament types, please extrude an additional 1 metre of filament to extrude it completely and remove the remaining filament.

1. Use diagonal pliers to cut the thread at an angle of 45°.
2. Feed the filament through the upper part of the printer.
3. Feed the filament into the extruder
4. Click on "Actions > Feed filament > Temperature". You can now set a nozzle temperature of 180°C and return to extruding. Press the filament down while clicking on "Extrude or Load" to load the filament.
