Newbie having trouble slicing fine detail on mesh

Recommended Posts

Posted (edited) · Newbie having trouble slicing fine detail on mesh

I'm using FreeCad v0.18 and Cura 4.0.0.  These tools are new to me.

 

I have a simple model that I want to emboss text onto.  Cura displays the text but does not slice it.  Slicing height is 0.15 so I set the text height at 0.45 but it still ignores it.  The text size is pretty large and I've tried increasing the size and the height to ridiculous proportions.

 

I haven't been able to get MeshLab working to examine the mesh but I will continue working on it.

 

Still, Cura displays the mesh when I open the .obj (alias mesh) in Cura.  The text looks perfect.  When I slice and preview, the text goes away.

 

Any help would be appreciated!  Thank you in advance.

I should mention I'm using Manjaro Linux.  Kernel 4.19.42.

I've attached a sample of the problem.  This object displays properly in Cura but the text is gone from the preview after slicing.

 

DiskTest v0.01.obj

Hello @TomB19, I tried loading that obj file into cura and it complained saying the file was invalid.

 

I then loaded it into FreeCAD and exported it as an STL which cura did load but then complained that the model wasn't watertight.

 

I then checked the original obj model in FreeCAD and it showed these errors:

So perhaps the model needs fixing before you can print it?

Thank you for the help, burtoogle.  🙂

 

I'm pretty confident the problem is with the font.  A different font solved the problem.

 

I thought it might be Cura, since it slices fine with Slic3r.

 

I can see the errors you indicate.  Thanks for showing me this technique.  I will play with the mesh and see if I can get this font working.

 

Cura is awesome.  I really appreciate this tool.  Thanks to all who have worked on it.  I've only sliced a few dozen things and already love it, compared to my old slicer.

 

I don't see a way to mark this "SOLVED".  If anyone finds this with a search, check your font.  Cura is functioning fine in this situation.
