3. Setup Instructions
- Placement: Place the eBOX Lite on a stable, flat surface away from direct sunlight, heat sources, and excessive humidity. Ensure adequate ventilation around the unit.
- Power Connection: Connect the provided power adapter to the DC input port on the back of the eBOX Lite. Plug the adapter into a standard US power outlet (AC100-240V ~ 50/60Hz).
- Loading Filament:
- Open the transparent lid of the eBOX Lite.
- Place your filament spool onto the internal rollers. Ensure the spool rotates freely. The maximum compatible spool size is Φ200mm (diameter) x 73mm (height).
- Thread the filament through the designated outlet hole on the lid. If using the outlet conduit, attach it to the hole and thread the filament through it.
- Close the lid securely.

4. Operating Instructions
The eBOX Lite features a simple control panel with a display and buttons for setting temperature and time.
4.1. Control Panel Overview
- Display: Shows current settings (temperature level, time remaining).
- Mode Button: Used to cycle between temperature setting mode and time setting mode.
- Up/Down Buttons: Used to adjust values (temperature level, time).
4.2. Setting Temperature and Time
- Power On: After connecting the power, the display will light up.
- Set Temperature Level:
- Press the Mode button once to enter temperature setting mode. The display will show a number (1, 2, or 3).
- Use the Up/Down buttons to select the desired temperature level based on your filament type:
- Level 1: Approximately 40°C (suitable for PLA/PLA+)
- Level 2: Approximately 50°C (suitable for ABS/ABS+/PETG)
- Level 3: Approximately 55°C (suitable for PVA/Nylon/PC)
- Press the Mode button again to confirm the temperature level and proceed to time setting.
- Set Heating Time:
- The display will now show the time setting (e.g., "00.0h").
- Use the Up/Down buttons to set the desired heating duration from 0 to 18 hours. For optimal drying, eSUN recommends at least 2 hours for most filaments.
- Press the Mode button again to start the drying process. The display will show the remaining time.
The eBOX Lite will maintain the set temperature and humidity throughout the drying cycle. Once the time expires, the heating will stop, but the box will continue to provide a dry storage environment.

6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Power adapter not connected or faulty; power outlet issue. | Ensure power adapter is securely connected. Try a different power outlet. Check if the power adapter is damaged. |
| Filament not drying effectively. | Incorrect temperature level set; insufficient drying time; lid not closed properly. | Verify the correct temperature level for your filament type. Increase drying time (e.g., to 4-6 hours or more for very wet filament). Ensure the lid is fully closed. |
| Display is blank or unresponsive. | Temporary software glitch; power interruption. | Unplug the device, wait 30 seconds, then plug it back in. If the issue persists, contact customer support. |
| Filament spool does not rotate smoothly. | Spool too large or not seated correctly; debris on rollers. | Ensure spool dimensions are within specifications (Φ200mm x 73mm). Re-seat the spool. Clean the rollers. |
