¶ Fault Symptoms
- Model base does not adhere to the Build Plate
- Model detaches and falls off at a certain height during printing
¶ Possible Causes
- High resin viscosity, causing abnormal resin flow-back and incomplete curing of the model.
- Improper leveling, resulting in excessive gap between the Build Plate and the LCD screen.
- Contamination on the surface of the Build Plate.
- Loose or uneven installation of the LCD screen.
- Abnormal exposure state, poor contact of the LCD ribbon cable, or incorrect firmware version.
¶ Troubleshooting Steps
¶ 1. Check LCD Exposure
If there is no cured material on either the Build Plate surface or inside the Resin Tank, prioritize checking whether the LCD screen can properly expose and display the test pattern/logo.
When the LCD exposure is normal, the result should appear as shown below:
- Elegoo Logo
¶ 2. Clean the Resin Tank
¶ 3. Resin Preheating
The optimal printing temperature for resin is 25°C. If the ambient temperature where the printer is located is below 25°C, it is recommended to preheat the resin before printing.
The resin bottle can be immersed in warm water at approximately 60°C for about 10 minutes to reduce resin viscosity.
¶ 4. Enable Active Heating
If the printer supports external heating or built-in tank heating function, turn on the heating device in advance to preheat the internal chamber or the resin.
¶ 5. Modify Slicing Software Settings
Appropriately increase:
- Normal layer exposure time (1–3 seconds)
- Light-off delay (rest time after retraction)
For lift-type machines, the lift height can be increased appropriately (2–3 mm).
¶ 6. Check Firmware
Verify whether the machine firmware version is correct. If necessary, re-upgrade or flash the correct firmware version.
