I'm using a Prusa Slicer with a FlyingBear Ghost 4 and got a wrong printing alignments on the Y axis only on a part of the printing object. What may cause this? Here are the printed model pictures showing the problem: [![Photo of 3D print][1]][1] [![Close up of misalignment][2]][2] Here are the settings: # generated by PrusaSlicer 2.1.0+win64 on 2019-09-29 at 11:37:50 UTC avoid_crossing_perimeters = 0 bed_custom_model = bed_custom_texture = bed_shape = 0x0,255x0,255x210,0x210 bed_temperature = 60 before_layer_gcode = between_objects_gcode = bottom_fill_pattern = rectilinear bottom_solid_layers = 7 bridge_acceleration = 0 bridge_angle = 0 bridge_fan_speed = 100 bridge_flow_ratio = 1 bridge_speed = 60 brim_width = 0 clip_multipart_objects = 0 colorprint_heights = complete_objects = 0 cooling = 1 cooling_tube_length = 5 cooling_tube_retraction = 91.5 default_acceleration = 0 default_filament_profile = "" default_print_profile = deretract_speed = 0 disable_fan_first_layers = 3 dont_support_bridges = 1 duplicate_distance = 6 elefant_foot_compensation = 0 end_filament_gcode = ";
