5. Иштөө нускамалары
This section covers the basic steps for operating your Twotrees BLU-5 3D Printer.
5.1. Жүктөө Filament
- Жип катушкасын жип кармагычка коюңуз.
- Feed the filament through the filament sensor and into the extruder.
- On the touch screen, navigate to the "Load Filament" or "Extrude" option.
- Wait for the nozzle to heat up to the appropriate temperature for your filament type (e.g., 200-220°C for PLA).
- Once heated, the extruder will pull the filament through until it emerges from the nozzle.
5.2. Auto-Leveling the Print Bed
The BLU-5 features an auto-leveling function for precise bed calibration.
- Ensure the print bed is clean and free of debris.
- On the touch screen, select the "Leveling" or "Auto-Level" option.
- The printer will automatically probe multiple points on the print bed to create a mesh for compensation.
- Once complete, the printer is ready for printing.
5.3. Басып чыгарууну баштоо
- Prepare your 3D model using slicing software (e.g., Cura, Repetier-Host) and save it as a Gcode file onto an SD card.
- SD картаны принтердин SD карта уячасына салыңыз.
- On the touch screen, navigate to "Print" or "Files" and select your desired Gcode file.
- Confirm the print settings and start the print. Monitor the first layer to ensure proper adhesion.

| Ката коду | Description | Мүмкүн болгон себеп жана чечим |
|---|---|---|
| Err1 | Hotbed exceeds maximum temperature limit. | Check if the hotbed thermistor is short-circuited. |
| Err2 | Nozzle exceeds maximum temperature limit. | Check if the nozzle thermistor is short-circuited. |
| Err3 | Hotbed exceeds minimum temperature limit. | Check if the hotbed thermistor is disconnected. |
| Err4 | Nozzle exceeds minimum temperature limit. | Check if the nozzle thermistor is disconnected. |
| Err5 | Print head fails to heat up. | If the print head does not reach the set temperature difference within the set time, an error will be reported. Check configuration file settings or ensure power supply is sufficient. |
| Err6 | Hotbed fails to heat up. | If the hotbed does not reach the corresponding temperature within the set time, an error will be reported. Check configuration file settings or ensure power supply is sufficient. |
| Err7 | Thermal runaway. | When the temperature rises to the target temperature, if the current temperature fluctuates greatly within the set time, an error will be reported. Check if the thermistor is normal or if the PID value is appropriate. |
