Assembly

The Flsun S1 comes partially assembled. Follow these steps to complete the setup:

Attach the Frame: Secure the full-metal frame using the provided screws and tools.
Install the Build Plate: Place the textured PEI print plate onto the heated bed and secure it.
Connect the Extruder: Attach the dual-gear direct drive extruder to the effector.
Connect Cables: Connect all necessary cables to their respective ports, ensuring they are securely attached.
Power Up: Plug in the power cable and turn on the printer.

Initial Calibration

Before you start printing, you need to calibrate your Flsun S1 to ensure accurate prints.

Auto-Leveling: Utilize the auto-leveling feature to level the bed. The AI Lidar Detection system will assist in the first layer detection and ensure a perfectly level bed.
Nozzle Height: Adjust the nozzle height using the touchscreen interface. The recommended layer height is between 0.1mm and 0.35mm.
Flow Calibration: Calibrate the flow rate to ensure the correct amount of filament is extruded.
Accuracy Calibration: Use the touchscreen interface to calibrate the accuracy of the printer’s movements.

Preparing for Printing

Loading Filament

Filament Type: The Flsun S1 supports various filament types, including PLA, PETG, TPU, ABS, ASA, PVA, PET, PA, PC, and PLA-CF.
Load Filament: Insert the filament into the dual-gear direct drive extruder and feed it until it reaches the nozzle.
Filament Detection: The printer’s filament detection system will confirm that the filament is correctly loaded.

Slicing Your Model

Choose a Slicer: You can use the Flsun Slicer or third-party slicers compatible with the printer.
Import Model: Import your 3D model file (STL, OBJ, AMF, 3MF).
Configure Settings: Adjust settings such as layer height, print speed, and infill density. For optimal performance, consider the printer’s max speed of 1200mm/s and acceleration of 40000mm/s².
Generate G-code: Slice the model to generate the G-code, which is the file format the printer reads.

Starting Your Print

Transfer File: Use the 16GB EMMC or 32GB USB flash storage to transfer the G-code to the printer.
Preheat Bed and Nozzle: Preheat the bed to a maximum of 120℃ and the nozzle up to 350℃ as required by your filament type.
Print: Start the print from the touchscreen interface or PC. The printer’s camera with 1920 × 1080 pixels allows for real-time monitoring.

During the Print

Monitoring and Adjustments

Real-Time Monitoring: Use the camera to monitor the print process.
Filament Detection: The printer will automatically pause if it detects the filament is running low or clogged.
Debris Detection: The AI features can detect debris and other issues during the print.
Spaghetti Detection: The printer can detect and stop in case of spaghetti-like filament mess.

Smart Features

Vibration Compensation: Ensures stable and accurate printing.
Power Off Resume: If the power goes off, the printer will resume printing from where it left off once the power is restored.
Time-Lapse Photography: Capture the progress of your print with time-lapse photography.

Post-Printing

Removing the Print

Cool Down: Allow the build plate to cool down to avoid damaging your print.
Remove Print: Carefully remove the print from the textured PEI print plate.

Maintenance

Clean Nozzle: Regularly clean the hardened steel nozzle to prevent clogs.
Check Bed Leveling: Periodically check and re-level the bed if necessary.
Inspect Moving Parts: Ensure all moving parts are free of debris and properly lubricated.

Software and Firmware Updates

OTA Updates: Keep your printer’s firmware up to date with Over-The-Air (OTA) updates. This ensures you have the latest features and improvements.
