¶ 1)Sliced file error
Model errors may cause slicing problems. Please print the official test model to verify whether it is a model and slicing problem.
¶ 2)Increase the flow
First confirm that the diameter of filament in Cura is 1.75mm. Then increase the flow. Generally, when printing PLA, the default flow is 100%. You can try to adjust the flow to 105% ~ 110% and print again to check whether the shortage is improved.
