4. Operating Instructions

4.1 Bed Leveling

Accurate bed leveling is crucial for successful prints. The BIQU B1 offers guided leveling features. Navigate to the "Leveling" menu on the touchscreen. The printer will guide you through adjusting the bed at multiple points using a piece of paper to set the correct nozzle height.

For precise adjustments during the first layer, utilize the "Baby Step" feature on the touchscreen. This allows for micro-adjustments of the Z-offset to achieve optimal bed adhesion.

Figure 3: The "One Click First Layer Test" feature helps verify proper bed leveling by printing a test pattern.

The BIQU B1 also supports optional BL-Touch auto-leveling for enhanced convenience. Refer to the BL-Touch installation guide for integration.

4.2 Loading Filament

1. Place the filament spool onto the filament holder.
2. Preheat the nozzle to the recommended temperature for your filament type (e.g., 200°C for PLA).
3. Insert the filament into the extruder's input hole and push it through until it emerges from the nozzle.

4.3 Printing Your First Model

1. Prepare your 3D model using a slicing software (e.g., Cura, PrusaSlicer) and save it as a G-code file on a TF card or USB disk.
2. Insert the TF card or USB disk into the corresponding slot on the printer.
3. On the touchscreen, navigate to the "Print" menu and select your G-code file.
4. Confirm the print settings and start the print. Monitor the first layer to ensure proper adhesion.

5. Maintenance

5.1 Cleaning the Build Plate

Regularly clean the spring steel build plate with isopropyl alcohol to remove any residue and ensure optimal adhesion for future prints. Allow it to dry completely before starting a new print.

5.2 Nozzle Maintenance

Periodically check the nozzle for clogs or wear. If necessary, clean the nozzle using a thin needle or replace it. Ensure the hotend is heated before attempting any nozzle maintenance.

5.3 Lubrication

Apply a small amount of lithium grease to the Z-axis lead screw and X/Y axis smooth rods every few months to ensure smooth movement and prevent wear.

5.4 Belt Tension

Check the tension of the X and Y axis belts. They should be taut but not overly tight. Adjust the tensioners if the belts feel loose to prevent layer shifting and improve print quality.
