OK, I totally messed up some parameter, somewhere in the application. everything I print is very weak, transparent (at 3 outside perimeter thickness), spongy looking, (you can see and feel it looks very "spongy"), falls apart when twisting the print. I don't know how to recover. would my best bet be to uninstall the application and then reinstall (to get back to the default settings)? I only use slic3r, not cura ( using this slicer will not give me a top layer on the prints). I've never even tried the third slicer, it seemed awkward. Any ideas?
