4. Muntatge i muntatge
The Tronxy X5SA-400 Pro is a DIY kit that requires assembly. This process involves connecting various components and debugging. It is recommended for experienced users. Please refer to the official assembly guide provided with your printer (paper manual or electronic version) and any available installation videos for detailed step-by-step instructions.
4.1 Key Assembly Components
- Muntatge del marc: Connecta l'alumini professionalfiles to form the printer's structure.
- Sistema de moviment: Install the XY gantry, belts, and dual Z-axis components.
- Capçal d'impressió: Mount the Titan Extruder and hotend assembly.
- Llit escalfat: Install the grid glass print platform and connect its wiring.
- Electrònica: Connect the control board, power supply, TR auto-leveling sensor, and filament sensor.
- Pantalla tàctil: Mount and connect the user interface.
4.2 Initial Leveling (TR Auto-Leveling Sensor)
The TR auto-leveling sensor simplifies bed leveling. After assembly, perform the initial auto-leveling procedure as described in the detailed assembly guide. This sensor is designed to accurately detect the print surface, including lattice glass, PC board, PVC stickers, and metal materials.

Figure 4.2: The upgraded lattice glass platform allows for easy removal of printed models by hand, unlike PVC sticker platforms which often require a shovel.
5. Instruccions de funcionament
5.1 Càrrega del filament
- Ensure the hotend is preheated to the appropriate temperature for your filament type (e.g., 200-220°C for PLA).
- Insert the filament into the filament sensor.
- Feed the filament through the Titan Extruder and into the hotend until molten filament extrudes from the nozzle.

Figure 5.1: The Titan Extruder is designed to handle various filament types, including flexible materials like TPU, as well as PETG, PLA, ABS, and PA.

Figure 5.2: The filament sensor detects when the filament runs out or breaks, pausing the print and alerting the user to allow for filament replacement.
5.2 Inici d'una impressió
- Prepare your 3D model using a slicing software (e.g., Cura, Simplify3D) to generate G-code.
- Transfereix el codi G file to the printer via USB or SD card.
- Seleccioneu el file from the printer's touchscreen interface.
- Initiate the print. The printer will automatically preheat and perform any necessary auto-leveling before starting.
6. Manteniment
Un manteniment regular garanteix un rendiment òptim i una llarga vida útil de la impressora 3D.
- Clean the Print Platform: After each print, clean the grid glass platform with isopropyl alcohol to ensure good adhesion for subsequent prints.
- Neteja de broquets: Periodically clean the nozzle to prevent clogs. Use a brass brush or needle to remove any accumulated filament.
- Lubricar les peces mòbils: Apply a small amount of lithium grease or similar lubricant to the lead screws and smooth rods every few months.
- Revisar cinturons: Ensure the XY belts are properly tensioned. They should be taut but not overly tight.
- Inspeccioneu el cablejat: Regularly check all electrical connections for any signs of wear or looseness.

Figure 6.1: The OSG External Dual Axis Guide system, featuring full belt drive and dual Z-axis, requires occasional inspection for smooth operation and belt tension.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| First layer not sticking | Bed not level, nozzle too far from bed, dirty print surface, incorrect bed temperature. | Perform auto-leveling, adjust Z-offset, clean print surface with isopropyl alcohol, verify bed temperature settings. |
| El filament no s'extrudeix | Nozzle clog, tangled filament, incorrect hotend temperature, extruder gear slip. | Clear nozzle clog, untangle filament, check hotend temperature, clean extruder gear. |
| Mala qualitat d'impressió (canvi de capes, encordat) | Loose belts, incorrect print speed, retraction settings, worn nozzle. | Check and tension belts, adjust print speed and retraction settings in slicer, replace nozzle if worn. |
| Filament sensor alarm | Filament run out or broken. | Replace filament and resume print. |
