Top/bottom engraving issue

Posted · Top/bottom engraving issue

I'm trying to 3D print a die for use in a game designed by my grandson.
Each face has a symbol engraved on it.
The vertical faces print well, but the top and bottom don't.  The engravings are filled in and barely visible.  From looking at the top and bottom layers in Cura, this appears to be happening during slicing.

 

Workflow is:
  .jpg -> Inkscape - trace path, save as .svg ->  Tinkercad - import .svg (scaling 5%), add to die as a hole, export .stl -> Cura

 

Using Cura 3.6, Ender 3 'Normal' profile except
Fill gaps between walls - nowhere (thought this might be the problem)
Infill 10% Gyroid ('cos it looks fun!')
Initial Layer 20mm/s
Combing Not in Skin
Skirt

 

Two guesses as to source of issue
1. There is a Cura setting that I need to change to keep the engraving unfilled - if so where?
2. The engraving lines are just too fine for Cura to cope.  If so, why are the vertical sides fine?

Any suggestions gratefully received.

    Well, it seems to me that the top and bottom engravings have narrower gaps than the sides. Compare the images below. If you look at the model using the Cura solid view, do all the engravings have roughly equal size gaps?

    For the bottom layer, make sure that the z-height is not too low which would squish the filament out more.

    Also, I would not use a brim for this model as the flat bottom is going to stick very well.

     

    Here's the bottom and the gap between the outer walls is only about a line width wide.

    Here's the side and the gap is more like 2 or more line widths wide

    Thanks for the suggestions.  I'll have a closer look at things in Inkscape and try to adjust.

    You're right about the brim, after the first print it was clear that I didn't need it.  Given the line that Cura now prints on the left of the build plate, I'm not sure I even need a skirt, which is what I normally do.

     

    Thanks again for your help.
