I think I got my settings right, finally. I installed Cura on a Win 10 system and that's working now. I will try the settings on my Linux machine later. Here's my first miniature that actually printed correctly, Jack the Giant Killer.
I didn't sculpt this. I downloaded the file from thingiverse. https://www.thingiverse.com/thing:3750572 My granddaughter can actually sculpt with a computer program and then print to their 3D printer.
I have some grey filament coming today. I'm almost out of the white that came with the printer. I think the grey will be better for miniatures. And I found a thingiverse thing that is customizable dice. Six siders where you can use your own art.
