¶ 1. Phenomenon Description
Abnormal noise occurs during printing.
¶ 2. Cause Analysis
- Resonance
- Leading screw, idler wheel or optical shaft is not smooth, causing excessive friction
- Damaged idler wheel/motor
¶ 3. Troubleshooting
¶ 3.1 Modify jerk speed and infill:
For resonance noise, there's no permanent solution, only temporary optimization. Place the model at a 45-degree angle and change the infill pattern to honeycomb. Also, reduce the jerk speed.
¶ 3.2 Adjust belt tension and apply lubricant:
Apply lubricant to the optical shaft, idler wheel, and leading screw. Refer to the Equipment Maintenance in the user manual.
¶ 3.3 Identify the source of abnormal noise:
- Move the hotend in the Y-axis direction to rule out idler wheel noise from both ends of the X-axis (X-axis idler wheels won't move at this time, refer to arrow 1 direction. If there's no noise, the abnormal sound is coming from the X-axis idler wheels, which can be further troubleshooting individually).
- Move at a 45-degree angle to the left in the Y-axis direction to rule out X-axis motor assembly idler wheel noise (Y-axis motor assembly won't move at this time, refer to arrow 2 direction. If there's no noise, the abnormal sound is coming from the front and back of the Y-axis motor, which can be further troubleshooting individually).
- Move at a 45-degree angle to the right in the Y-axis direction to rule out Y-axis motor assembly idler wheel noise (X-axis motor assembly won't move at this time, refer to arrow 3 direction. If there's no noise, the abnormal sound is coming from the front and back of the X-axis motor, which can be further troubleshooting individually).
