我在带有 AMH/DD 的 Ender 3 上用 PETG 打印的照片上有很多斑点和磨损。如果印刷品的底部没有那么多平底，它似乎不会这样做。

我将 E-steps 设置为 130，如果有的话，与卡尺测量值相比，挤出稍微不足。

有什么想法可以解决这个问题吗？

库拉设置：

[general]  
version = 4  
name = Creality Ender 3 - eSUN PETG - Red  
definition = creality_base  

[metadata]  
type = quality_changes  
quality_type = standard  
intent_category = default  
position = 0  
setting_version = 17  

[values]  
cool_fan_full_layer = 3  
infill_overlap = 15  
infill_pattern = triangles  
infill_sparse_density = 10
ironing_enabled = False
ironing_only_highest_layer = True
material_print_temperature = 230
retraction_amount = 2
retraction_speed = 25
skirt_gap = 6

speed_travel = 250.0
speed_wall = 25
