Posted · Convert Gcode File back to STL

Hi

 

I have been working on a project to develop a vase for raspberry pi 4. I have the gcode files and needed to make a change to the design.

Unfortunately i cannot find the source STL file. IS it possible to bring the gcode file back into Cura and change it back to an 

STL file so it can be edited and converted back to an STL.

    Timeout here @AndersK.  There is no mesh/model in a gcode file...just lines in space.  I don't see any way this can be done.

     

    Typically I "read" the gcode into AutoCad with a macro and then design a new model around the wireframe.  The wire frame is undersized by 1/2 line width in the +X and -X as well as the +Y and -Y and at the base that was resting on the build plate.  That's another of the reasons it can't be converted.

    If you want to post the gcode I can turn it into a DXF file (consisting of a lot of lines in space) and post it back.

    I said the quality might be bad 😉

     

    Yes youre right, the option is there but it doesnt generate a mesh.

    It would be possible though , all information needed is in the code.

    Triangulate between the layers and top bottom in that DXF and its there.

    When I first found this site and started reading through threads I was amazed at how many bugs Cura was being accused of.  I had not found any and here were these people complaining about it.

    In order to take Cura out of the loop I altered a macro I had written years ago to translate CNC gcode files back into lines in AutoCad.  Now, independent of Cura, I can look at a gcode file and really see what's going on.

     

    I've had to re-build models from the gcode data a couple of times.  It isn't any fun.

    If one is looking for a robust gcode to stl generation (deslicing) tool, there is a slicer called Voxelizer that has this capability.  It has been my experience that it works well.  More info: https://all3dp.com/2/g-code-to-stl-how-to-convert-g-code-back-to-stl/

    I see they now have an 'experimental' version of this for Linux.  Previously it was for Mac and Win machines only.

     

    I'm downloading it now, and I'll give it a try.  It could come in very handy.
