The FLSUN S1 is designed for high-speed and precise 3D printing.
5.1 Ilana titẹ sita
- Prepare Model: Use a compatible slicing software to prepare your 3D model (.STL, .OBJ, etc.) and generate a G-code file.
- Gbigbe koodu G: Gbe koodu G-gbe file to the printer via USB or network connection.
- Select and Start Print: On the printer's touchscreen, select your G-code file and initiate the print. The printer will automatically preheat the nozzle and bed to the required temperatures.
- Monitor Print: Monitor the printing process. The built-in AI Camera can self-optimize print quality and proactively alert you to potential issues. Remote monitoring is also available.
- Fọtoyiya-Laipe: The AI Camera can capture time-lapse videos of your prints.

| Isoro | Owun to le Fa | Ojutu |
|---|---|---|
| Print not sticking to bed | Bed not level, incorrect bed temperature, dirty print surface. | Perform automatic bed leveling. Adjust bed temperature in slicing software. Clean the print surface with isopropyl alcohol. |
| Fíìmù kò jáde kúrò | Nozzle clogged, filament tangled, incorrect nozzle temperature. | Clear nozzle clog. Ensure filament spool is free. Verify nozzle temperature is appropriate for the filament type. Check for material shortage olurannileti. |
| Poor print quality (layer shifts, rough surfaces) | Vibrations, incorrect print speed, mechanical issues. | Ensure printer is on a stable surface. The S1's vibration compensation should mitigate this; if not, check for loose components. Adjust print speed. The AI Camera may alert to issues. |
