Rep Host crashes when slicing using curaengine

edited March 2 in Linux

Problem as per subject

OS is Fedora 25

Slicing with Slic3r works well, and using curaengine works sometimes, but more often that not it crashes ( Ihavent worked out if theres any pattern to it yet )

here's the terminal output:

[lots of these...]
libpng warning: iCCP: known incorrect sRGB profile
libpng warning: iCCP: cHRM chunk does not match sRGB

(sorry cant see any way to format code etc)

Thanks for any input to resolve



  • Looks like CuraEngine did not slice and output file is not present. Normally a result of wrong slicing parameter. Why that crashes host under linux is not clear - in windows it shows the slicing error instead.
