Cause 1: Impurities in the filament or mismatch between the model printing temperature and filament temperature
Solution:
Cause 2: Carbonized filament buildup on the nozzle
Issue: During manual filament feeding, the extruded filament diameter is less than 0.45mm. The normal diameter shall be around 0.5±0.03mm.
Solution: Replace the nozzle.
Cause 1: Z-axis movement is not smooth.
Issue: Abnormal noise or jamming during Z-axis up-and-down movement.
Solution: Apply grease to the Z-axis lead screw.
Cause1: Insufficient belt tension
Solution 1:
Solution 2:
Cause 1: Overhangs at large angles
Solution 1: Enable “Slow down for overhangs” in OrcaSlicer.
Solution 2: Add supports for overhangs at an angle greater than 30°.
Solution 3: Increase the cooling fan layer time and reduce the minimum print speed in OrcaSlicer.
Cause 2: Malfunctioning cooling fan and auxiliary fan
Solution: Please refer to the video for instructions on [replacing the cooling fan and turbo fan](/en/adventurer-series/maintenance/ad5mseries-replace-the-turbo-fan-and-cooling-fan =650x).
Cause 1: Filament that has absorbed moisture can become brittle and prone to breaking (especially for PLA, PETG, and ABS).
Solution : Dry or replace it with a newly unpacked filament.
Cause 2: Insufficient retraction
Solution: Use OrcaSlicer to increase the retraction amount and retraction speed appropriately, and enable “Retract on layer change” and “Wipe while retracting”.
Cause 3: Incorrect temperature setting
Solution: Adjust the extruder temperature.
Cause: Model printing speed too fast, insufficient cooling
Solution 1: Reduce the print speed in the slicer.
Solution 2: Adjust the “Deceleration Area Threshold” in the slicer to make the printer automatically slow down for smaller areas of the model.
