¶ Issue Description
The printed model exhibits highly irregular layer lines with significant layer shifting, resulting in poor surface quality.
¶ Troubleshooting
Layer lines are a common quality issue in 3D printing, typically caused by a loose or improperly installed nozzle assembly. The following sections provide detailed troubleshooting steps for different printer series (A1, H2D, and X/P series) to help you quickly identify and resolve the issue.
¶ H2D & A1 Series Printers
Nozzle looseness is a primary cause of layer line issues in H2D and A1 series printers. Follow these steps to troubleshoot:
¶ 1. Check Nozzle Clip Installation
- Procedure: Remove the silicone cover from the nozzle assembly and carefully inspect whether the hotend clip is securely fastened.
- Note: An improperly installed clip may cause slight nozzle movement during printing, leading to layer lines.

¶ 2. Inspect Clip for Deformation
- Procedure: Check the clip for any signs of deformation, cracks, or wear. A deformed clip may fail to secure the nozzle assembly properly.
¶ 3. Verify Nozzle Assembly Magnet
- Procedure: Ensure the magnet on the nozzle assembly is intact and securely attached. A missing or loose magnet can prevent the nozzle from fitting tightly to the print head.
¶ 4. Check Nozzle Assembly Stability
- Procedure: After completing the above checks, gently shake the nozzle assembly by hand to check for noticeable movement.
- Criteria: If the nozzle exhibits obvious movement, the hotend is not fully secured, and the clip needs to be reinstalled.
¶ X/P Series Printers
For X/P series printers, layer line issues are often related to loose nozzle fixing screws. Follow these troubleshooting steps:
- Procedure: Use an H2.0 screwdriver to verify that the fixing screws on the nozzle assembly are fully tightened.
