MatterControl 2.0 with Cura 4.7.1

[MattyLou 0]

I am new to 3D printing and am having an issue.  I have a Labists et4 printer and uploaded the recommended profile.  I used MatterControl 2.0 to create a project,  then when I opened it with Cura 4.7.1, it read "print setup disabled.  G code file cannot be modified."  Therefore, I had no ability to use any functions in Cura other than print my project.  Any suggestions?  should I try using a different CAD program?  Thanks for your time

slicers take as an input an STL file and as an output a gcode file.  The STL describes the model to print.  The gcode are commands to the printer.

 

So the problem you had was that you were giving cura a gcode file.  Instead give it an STL file.  I mean cura can read gcode files and display them but that's it.  you can't slice something that is already sliced.
