¶ 1.Troubleshooting Procedure
The machine may encounter problems during operation. Causes can include hardware connections, software errors, network issues, user settings, material properties, or environmental factors.
You can view these codes:
- In the PC software when an error pop-up appears.
Please use the module code above to locate your specific error code. Based on those error codes, you can find the likely cause and recommended action in the table below.
| Error Code | Description | Recommended Action |
|---|---|---|
| 1100101 | Laser module signal abnormality. Please check that the laser module is correctly installed. [1100101] | Power off the machine and reseat the laser module. Make sure the module is fully seated in the mount and that the pins and cables are clean, secure, and undamaged. If the error remains after restarting, export the error information and contact Support to check the laser module or main-control communication. Reference manual: Replace the laser moudle |
| 1100102 | Laser module temperature sensor abnormality. [1100102] | Do not continue processing while the temperature sensor is abnormal. Power off the machine, reinstall the laser module, and check the connector. If the error remains after restart, contact Support and treat it as a laser-module fault. Reference manual: Replace the laser moudle |
| 1100103 | Device accelerometer abnormality. [1100103] | Check that the machine is placed on a stable, level surface and that it was not bumped or shaken during operation. If the error remains after restart, contact Support to inspect the laser-module accelerometer or control board. |
| 1100104 | Laser module cooling abnormality. Please check cable connections and fan speed for any issues. [1100104] | Check whether the laser-module cooling fan is blocked by dust, jammed by debris, or affected by a loose cable. Clean the fan and heat sink, then restart the machine. If the error persists, contact Support to inspect the fan or laser module. Reference manual: Deep Clean: Laser Module & Cooling Fans, Laser Module High Temperature Alarm |
| 1100105 | Laser module cooling abnormality. Please check cable connections and fan speed for any issues.
