2. Setup and First Use
The FLSUN S1 is designed for quick and easy setup, allowing you to begin printing within minutes of unboxing. The machine comes fully assembled, requiring minimal user intervention.
2.1 Unboxing and Placement
Carefully remove the printer from its packaging. Ensure it is placed on a stable, level surface with adequate space around it for operation and ventilation. Verify all components are present as listed in the packing guide.
2.2 Automatic Leveling
The FLSUN S1 features an advanced FLSUN 2.0 algorithm for fully automatic one-button leveling. This simplifies the bed calibration process significantly.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your FLSUN S1 3D Printer.
4.1 Print Bed Cleaning
To maintain good filament adhesion, regularly clean the print bed with isopropyl alcohol to remove any fingerprints, dust, or debris. This should be done after several prints or if adhesion issues arise.
4.2 Lubrication of Moving Parts
Periodically re-lubricate the smooth rods and other moving mechanical components with a suitable dry lubricant (e.g., PTFE spray) to ensure smooth operation and reduce noise.
4.3 Nozzle and Hotend Care
The nozzle is a consumable part and will degrade over time. Replace the nozzle or the entire hotend assembly when print quality deteriorates. Consider upgrading to a full E3D V6 hot-end assembly for enhanced performance and durability. It is also recommended to upgrade the Bowden PTFE tube to a Capricorn tube for better heat resistance, especially when printing at higher temperatures, to prevent carbonization and fume exposure.
5. Troubleshooting Common Issues
This section addresses some common issues users might encounter and provides potential solutions.
5.1 Print Quality Issues (e.g., "Salmon Skin")
If you observe wavy outer walls or a "salmon skin" effect on your prints, this can be caused by stepper motor drivers. Installing 8-diodes TL-smoothers can mitigate this issue by preventing power feedback to the drivers.
5.2 Extruder Calibration (E-steps)
For optimal extrusion accuracy, it may be necessary to calibrate your extruder's e-steps per millimeter. This involves marking a length of filament, extruding a specific amount, and adjusting the e-steps value in the printer's firmware or settings based on the actual extruded length.
5.3 Printer Forgetting Settings
If the printer loses settings (e.g., auto-leveling, Z-height) after a power cycle, ensure that settings are properly saved to the printer's memory after adjustment. Consult the official manual or community resources for specific saving procedures.
5.4 Seeking Further Support
For issues requiring technical assistance or warranty service, it is recommended to contact the seller directly through the platform where the purchase was made. They can provide guidance or connect you with FLSUN support. Additionally, active online communities, such as the FLSUN Facebook group, can be valuable resources for firmware, test files, and user-generated FAQs.
