1.3 PEI Bed Preparation and Filament Loading

Ensure the steel spring PEI sheet bed is securely placed on the print platform. For optimal adhesion, clean the PEI surface with 70% isopropyl alcohol before each print. Load your chosen filament into the direct drive extruder. The V400's direct drive system is designed for reliable feeding of various filament types.

1.4 Automatic Leveling System

The FLSUN V400 features an upgraded automatic leveling system with 25-point precise calibration. Initiate the auto-leveling process through the Speeder Pad interface. This ensures a perfectly level print surface for consistent first layers.

3. Manutenzjoni

Regular maintenance ensures the longevity and optimal performance of your FLSUN V400 3D Printer.

3.1 Tindif tas-Sodda tal-Istampar

After each print, allow the PEI sheet bed to cool down. Once cool, models can be easily removed by flexing the steel spring sheet. Clean the surface with 70% isopropyl alcohol to remove any residue and ensure strong adhesion for subsequent prints.

3.2 Nozzle and Extruder Care

Periodically inspect the bi-metal 300℃ high-temp nozzle for any clogs or wear. If necessary, perform a cold pull or use a nozzle cleaning needle to clear obstructions. Ensure the direct drive extruder gears are free from filament debris.

3.3 Linear Guide Lubrication

The dual-axis linear guide system benefits from occasional lubrication to maintain smooth operation and minimize noise. Refer to the detailed maintenance guide for recommended lubricants and application frequency.

3.4 Ħażna tal-Filament

Store filaments, especially hygroscopic materials like NYLON, in a dry environment. Using a filament dryer for such materials before printing is highly recommended to achieve the best print quality and prevent issues like stringing or poor layer adhesion.

4 Issolvi l-problemi

This section addresses common issues you might encounter during the operation of your FLSUN V400 3D Printer.

4.1 Adeżjoni ħażina tal-Ewwel Saff

• Naddaf is-Sodda tal-Istampar: Ensure the PEI sheet is thoroughly cleaned with isopropyl alcohol before each print.
• Re-run Auto-Leveling: If issues persist, perform the 25-point automatic leveling calibration again to ensure proper bed height.
• Aġġusta Z-Offset: Fine-tune the Z-offset during the first layer of a print to achieve optimal squish.

4.2 Clogging or Under-extrusion

• Iċċekkja ż-Żennuna: Inspect the nozzle for blockages. A cold pull or cleaning needle can often resolve this.
• Filament Quality/Drying: Ensure your filament is dry, especially for hygroscopic materials. Wet filament can cause steam and bubbles, leading to poor extrusion.
• Extruder Gears: Verify that the direct drive extruder gears are not clogged with filament dust and are gripping the filament properly.

4.3 Print Quality Issues (Layer Shifting, Poor Surface Finish)

• Check Belts/Rods: Ensure the carbon fiber rods and linear guides are clean and moving freely.
• Veloċità tal-Istampar: While the V400 is fast, ensure your print speed is appropriate for the filament and model complexity.
• Tkessiħ: Verify that the fast cooling fan is operating effectively, especially for PLA.
