um1 weird layering for tighter curves in mesh

[kwatts 0]

Hi there,

 

I have been printing plenty of semi organic and mechanical models for years, its come to the time where i need to do some sculptures that were modeled in zbrush.

 

This print i did last night, 8hrs @ 50mm/sec 100mircons on an um1.

 

 

If you look at the images, the half sphere the character is sitting on and parts of her dress and face, the layering is beautiful . but when it comes to the legs, arms and hair, the layering is not what i expected.

 

Im not entirely sure what i need to change, in order to get these layers to print as good as the rest of the model.

 

 

Also here is the profile that was used to print the model:

layer_height = 0.1

wall_thickness = 1

retraction_enable = True

solid_layer_thickness = 1

fill_density = 15

nozzle_size = 0.4

print_speed = 50

retraction_dual_amount = 16.5

retraction_min_travel = 1.5

retraction_minimal_extrusion = 0.02

retraction_hop = 0.0

bottom_thickness = 0.2

object_sink = 0.0

overlap_dual = 0.2

travel_speed = 140

bottom_layer_speed = 20

raft_line_spacing = 1.0

raft_base_thickness = 0.3

raft_base_linewidth = 0.7

raft_interface_thickness = 0.2

raft_interface_linewidth = 0.2

fix_horrible_union_all_type_a = False

fix_horrible_union_all_type_b = False

fix_horrible_use_open_bits = True

fix_horrible_extensive_stitching = False

plugin_config =

object_center_x = -1

object_center_y = -1

 

edit: im using cura 14.03. am downloading latest cura, to try that.

 

If anyone has time to help me debug this it would be greatly appreciated.

Im going to print some smaller busts of the model to see if it is profile settings i need to change....

 

Cheers

personally I find a lower print speed more layers and maybe try with NO infill

I find that the infill sometimes interferes with that nice round movement and jerks off and then over sails a bit.

Plus check all the usual culprits like well lubricated rods, tight belts & pulleys. firmly sitting on its base etc.

But I think sloooower is probably one of the biggest helps.

Thanks James,

Ill try these suggestions over the next few nights

if i remember well 14.03 had some surface quality problems, maybe try with 14.09?

I would also lower the print speed to 30mm/s and lower the temperature in accordance (around 200°c)
