Known bugs and issues

Stringing and oozing

Solution:

1. Increase retraction distance (start with 2mm, adjust as needed)
2. Reduce nozzle temperature by 5°C
3. Enable "combing" in your slicer
4. Increase travel speed for non-print moves
5. Run a flow rate calibration cube to find the optimal extrusion multiplier

Layer separation / weak prints

Solution:

1. Ensure proper bed adhesion (use a heated bed or hairspray)
2. Check filament dryness — store in a sealed bag with desiccant
3. Slow down print speed for the first few layers
4. Reduce cooling fan speed for the first 2–3 layers

Warping

Solution:

1. Use a heated enclosure or build chamber
2. Increase bed temperature (60–70°C for PLA, 100–110°C for ABS)
3. Apply a brim or raft
4. Ensure good draft shielding in the print enclosure

Step-by-step fix procedures

Fix stringing

1. Run a retraction calibration test (print a tower test)
2. Adjust retraction distance (start at 2mm, increase by 0.5mm)
3. Reduce nozzle temperature by 5°C
4. Run a flow rate calibration to find optimal extrusion rate
5. Enable "combing" in the slicer settings

Fix layer separation

1. Ensure bed adhesion: clean build plate with isopropyl alcohol
2. Apply a thin layer of PVA glue or hairspray for difficult filaments
3. Increase bed temperature by 5°C
4. Slow down first-layer print speed
5. Store filament in a dry box

Optimization and tuning

Ink cost optimization

• Switch to EcoTank/MegaTank bottle systems (saves 90% vs cartridges)
• Enable "draft" mode for everyday printing
• Print in grayscale when color is not needed
• Use the printer's schedule ON/OFF feature to run weekly cleaning cycles

Print quality optimization

• Calibrate color profile for your specific paper type
• Use high-quality paper (acid-free, archival for photos)
• Enable high-resolution mode for important documents
• Run a maintenance cycle once a month

Wi-Fi optimization

• Place the printer within 10 feet of the router
• Use 2.4 GHz for better compatibility with mobile devices
• Set a static IP address for reliable access
• Keep firmware updated for improved connectivity

• Store paper in a cool, dry place away from direct sunlight

Troubleshooting flow

When issues occur:

1. Identify the specific symptom (error code, behavior change)
2. Check the last change (firmware update, OS update, new cable)
3. Try a power cycle (unplug 30 seconds, reconnect)
4. Check for firmware updates
5. If unresolved, search for the exact error code + P1S + Bambu Lab
6. Contact Bambu Lab support with your serial number and purchase date
