Check for proper bed leveling, appropriate extruder calibration, and correct filament diameter settings. Additionally, make sure your filament is of good quality and stored in a dry environment to avoid moisture-related issues.
3. Extruder Skipping Steps: If your extruder is skipping steps or experiencing under extrusion, first check the extruder gear for any debris or blockages. Ensure that the filament path is clear and that the idler tension is properly adjusted. You may need to adjust the extrusion steps per millimeter (E-step) value in your Klipper configuration file if the extruder is consistently under or over-extruding.
4. Heating Issues: If you’re experiencing inconsistent or inaccurate heating, verify that the temperature sensor is securely attached to the hotend or heated bed. Also, check the wiring connections for any loose or damaged connections. Perform a PID tuning process to ensure proper temperature control. Additionally, make sure your power supply can handle the required current to maintain consistent heating.
5. Layer Shifting: If your printed layers are shifting or the print is not aligned, check for any loose belts or pulleys on your printer. Ensure that the motor drivers are set correctly in the Klipper configuration file and that the stepper motor connections are secure. Adjust the stepper driver current if necessary to maintain proper motor performance.
6. Unexpected Movements: If you notice unexpected movements or random pauses during printing, review your G-code files and make sure they’re compatible with Klipper firmware. Some slicers may generate code that is not fully compatible with Klipper. You can also try to lower the maximum print speed to see if it helps stabilize the movements.
If you’re unable to resolve the issue using these troubleshooting tips, reach out to the Klipper community for assistance. The Klipper GitHub page and forums are filled with experienced users and developers who can provide guidance and support.
