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.

    Thanks for the link...  Quite surprised by the quality of the result. On the right the original benchy, on the left the model recreated from the Cura Gcode and reintegrated in Cura.

    I have tried to start Voxelizer, both the so-called 'experimental' version for Linux and the Windoze version running under wine, and when I try to register, the site it sends me to fails.

     

    Any hints?

     

    Thanks

    I don't know just downloaded the Windows Voxelizer for Fab  version  : https://zmorph3d.com/wp-content/uploads/2020/12/voxelizer3.0.0.msi_.zip     No issue in my case.

    Then Just Import GCode -> VOXELIZE  PRECISE -> Then Export STL

    Ok, thanks, let me try that version and see if I can get it to work.

    Ok, I got that to load and execute under Wine without any formality, but it wants me to select either of two Zmorph printers, which I assume sets the flavor of gcode that it will reverse.

     

    I don't have a Zmorph printer.  I have the Ultimaker S5 which uses the Griffin gcode and a Prusa I3, which uses the Marlin flavor of gcode.

     

    Are you (or anyone) using this successfully with Ultimaker or Prusa gcode?

     

    Thanks.

    Marlin flavor  in my case  but as GCode are mainly different on M Code instruction which should not have any influence on the creation of the final rendering this should not generate any particular problems.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
         
         
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
         
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
         
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
         

         
        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
         
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
