Questions & Answers
FAQ
Q: What will happen if the machine is powered off while working？
A: It will stop working. The machine will be initialized when powered on.
Q: Why is the engraving effect so shallow？
A: The imported image should be clear. Make sure that you are focusing correctly before engraving and that the power and speed are appropriate.
Q: What should I do if the engraving effect is inconsistent in depth?
A: Ensure that the material to be engraved is flat. Observe the gradient on the machine to ensure that the machine is horizontal and has been properly adjusted according to the operation method of the user manual.
Q: How to focus？
A: Please place the multi-level fixed focus bar between the laser module and the processed material. Follow the tips and make the bottom of the laser module contact with the corresponding surface of the multi-level fixed focus bar. Finally, lock it with two hand screws on the right. For example, if you engrave or cut a 2mm basswood or other material.
Q: Will the laser damage the workbench?
A: The laser may penetrate the material and damage the workbench (especially when cutting). It is recommended to place objects on the bottom that cannot be penetrated by the laser, such as stainless steel plates, aluminum alloy plates, etc.
Q: Why can't the machine read the G-code file (or read the wrong file)？
A: 1) Please check if the TF card is inserted. The machine reads the latest engraving file(.gcode/.gc) in the root directory of the TF card by default. It is recommended to delete other engraving files in the root directory.
2) The gcode file can only be generated by LightBurn. If gc file is generated by default, please modify the file suffix to gcode manually.
Q: What should I do if the buzzer makes a rapid alarm sound?
A: In preview mode and engraving mode, if the machine turns on its side or moves, it will turn off the laser. The motor stops moving, the indicator light flashes, and the buzzer emits an alarm.
Solution: Please move the machine to its original position and press the “Frame” or “Start/Pause” button on the control panel to continue previewing or engraving after clearing the abnormality.
Q: What should I do if the machine cannot be turned on?
A: 1) Check the power plug is plugged in properly.
2) Check the power outlet is properly powered.
3) Check the power switch, emergency stop switch and child lock on the machine are turned on.
Q: Do I have to wear goggles?
A: The machine adopts the design of shading and eye protection and integrates the MEMS attitude sensor. The laser module will stop working when the machine turns on its side abnormally. Even so, we still recommend that you wear goggles while working.
Q: The buzzer suddenly emits a "beep" and then stops working. How to deal with it?
A: The machine has four limit switches. If the laser module exceeds the engraving area of the machine during working, the buzzer will beep, and the machine will stop working. At this time, it is necessary to adjust the position of the laser module and check the size of the graphics.
Q: What will happen if the belt is too loose or too tight?
A: The engraved graphics will be deformed and dislocated, obviously, like a circle changes into an ellipse.
Q: What material can I engrave or cut?
A: Engraving: Paper, Wood, Bamboo, Leather, Textile, Acrylic, Painted Metal, Plastic, etc.
Cutting: Paper, Wood, Bamboo, Cloth, Leather, Fabric, Acrylic, Plastic, etc.
Q: Can I engrave on cambered material?
A: Yes, but the radian of the material should not be too large. Otherwise, there will be slight deformation.
Q: Can I engrave on reflective/transparent materials such as ceramics/glass?
A: Yes, but you need to apply anti-reflective material on the surface of the material before engraving to ensure the engraving effect and prevent the reflected light from damaging the laser module.
Q: Why do I have different engraving effects in the same materials with different colors by using the same G-Code file?
A: Materials with different colors have different optical properties. They have a difference in absorbing and reflecting the energy of the laser. You can achieve the desired effect by adjusting the parameters.
Q: How to deal with the smoked traces on the surface of the material?
A: Reduce the power appropriately and use the air assist from Creality.
Q: Why is it unable to cut through the material?
A: 1. Ensure that the machine and engraving material are parallel to the workbench; 2. Ensure that the protective lens of the laser module is clean; 3. Refer to the user manual and focus correctly; 4. Refer to the recommended parameters in the TF card; 5. Gradually increase the number of passes or reduce the cutting speed appropriately；
Q: Should I use the air assist?
A: The powerful and stable airflow can blow away the smoke and dust effectively during cutting, protecting the lens of the laser module and ensuring the stability of the laser energy. It can reduce the surface temperature of the cutting material quickly. Blow away the hot smoke and dust to keep material surfaces clean. Make the cutting edge smoother and more delicate.
It is recommended to use weak airflow when engraving and strong airflow when cutting (the effect depends on the specific material).
Q: What files can I import to the software？
A: LaserGRBL (bmp/png/jpg/gif/svg)
LightBurn (bmp/png/jpg/jpeg/gif/tif/tiff/tga/ai/pdf/sc/dxf/hpgl/plt/rd/svg)
Q: What should I do if the software does not respond or it cannot be connected during online-working?
A: 1) Ensure that the Type-C data cable has the communication function and that the end of the data cable connected to the computer is a USB-A interface.
2) Ensure that you have imported the Creality Falcon2.lbdev file successfully.
3) The corresponding COM port of the machine is not occupied.
4) If it still can't be connected, please record a video and tell the customer service your system information and the version of the software.
Troubleshooting:
Q: The angle data is abnormal, and it has stopped working.
A: Please check whether the workbench is shaking, the screws are locked tightly, and the frame of the machine is firm.
Q: There is no G-Code file in the root directory of the TF card.
A: Please check whether the suffix of the file in the TF card is ".gcode/.gc/.nc ", and ensure the file is saved in the root directory.
Q: No airflow is detected and the machine has stopped working.
A: Please check whether the air pump is connected to the machine, check whether the knob switch on the left side of the machine is adjusted to the maximum, and check whether the silicone air tube above the laser module is inserted and there are no kinks in the tube.
In the Falcon Machine Settings, you can change $153 to 0 to cancel the alarm function (it is recommended to set it according to the actual situation).
Q: A flame has been detected and the machine has stopped working.
A: Please press the Reset button if the material is not burning, and the FIRE light will turn orange, indicating that there is a risk of fire. You can press the start button to continue working and after restarting the machine, the FIRE light will be green. Refer to “Laser Module Alarm Functions.pdf” for more information.
In the Falcon Machine Settings, you can change $154 to 0 to cancel the alarm function (it is recommended to set it according to the actual situation).
Q: Lens contamination is detected and the machine has stopped working.
A: Please press the Reset button, and the LENS light will turn orange. You can press the start button to continue working and the lens needs to be cleaned when powered off. The LENS will still keep the red light flashing when powered on. You need to press the reset button again to confirm that the lens is clean and the LENS light will be green. Refer to “Laser Module Alarm Functions.pdf” for more information.
In the Falcon Machine Settings, you can change $155 to 0 to cancel the alarm function (it is recommended to set it according to the actual situation).
Q: The temperature of the laser module is high, and it has stopped working.
A: You can press the Reset button and then press the Start button to continue the current work.
It is recommended to clean the laser module when powered off and wait for the laser module to cool down to a suitable temperature before working.
In the Falcon Machine Settings, you can change $158 to 0 to cancel the alarm function (it is recommended to enable the alarm function).
