5. Instruccions de funcionament
The FLSUN S1 is designed for high-speed and precise 3D printing.
5.1 Procés d'impressió
- Preparació del model: Use a compatible slicing software to prepare your 3D model (.STL, .OBJ, etc.) and generate a G-code file.
- Codi G de transferència: Transfereix el codi G file a la impressora mitjançant USB o connexió de xarxa.
- Selecciona i inicia la impressió: 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.
- Impressió del monitor: 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.
- Fotografia de lapse de temps: The AI Camera can capture time-lapse videos of your prints.

7. Solució De Problemes
This section addresses common issues you might encounter. For more complex problems, refer to the FLSUN support resources.
| Problema | Causa possible | Solució |
|---|---|---|
| La impressió no s'enganxa al llit | 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. |
| El filament no s'extrudeix | 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 recordatori. |
| 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. |
| La impressora no s'encén | Cable d'alimentació desconnectat, presa de corrent defectuosa. | Check power cable connections. Test power outlet with another device. |
