Cura 3.4.1 - Is Combing realy working?!

Is Combing really working? why all those straight travel movements between the hexagons?

And please optimize the toolpath generator, this is a big mess on a simple print as you can see on the image below.

Thanks

    Hi @amagro, I know what's happening now and have fixes for when combing is "all" and "no skin". I need to test the changes some more but it's likely that a future version of Cura will have a fix for this. Here's a couple of images showing the "all" and "no skin" results.

    Hello @smartavionics,

    Thanks for your prontitude on solving this issue.

     

    This model is for a school project and I needed to print some of them till the end of this week. 

    Is there any chance you could send me the Cura executable with your changes?

    Thanks

    Hi @amgro. I can only build Cura for use on Linux, I don't have any Windows computers  or Macs here. So I can offer you a Linux archive (just unpack and run the included script). Let me know if you want that. I attach the gcode for your current model. Please note that combing may not give you the best quality results with this model because in the honeycomb region the walls are very narrow and so the nozzle will be right on the edge of the walls in some places. Maybe in the future Cura will comb over thin walls better than it does now. It is still under development (like all of Cura, actually).

    Thanks again @smartavionics,

     

    I will print the gcode that you send me.

    So if you can, please send me the Linux archive with your Cura changes.

    You can find my Linux archives at https://www.dropbox.com/sh/s43vqzmi4d2bqe2/AAADdYdSu9iwcKa0Knqgurm4a?dl=0

    Just unpack somewhere and run cura/bin/cura.sh

    Sorry they are so big, I haven't succeeded in creating an appimage, these are just copies of my installation tree which has lots of files that you don't actually need. Good luck!

    Since I don't have enough knowledge to solve this error, could you please generate another gcode but now for a different printer?
    I send you the Cura project with the stl and the 3D printer.

    marcador_1.0.curaproject.3mf.zip

     

    Thank you very much.

    Hi @amagro, I attach the gcode. This was sliced with combing mode "no skin" and "avoid printed parts when travelling" turned off. I haven't printed it but the layer view looks OK.

     

    As for the gfortran error above, it looks like you need to install the fortran runtime libraries so do "sudo apt-get install gfortran" and it should download and install what you need.

    If you get the Linux version working, I will post another archive as I have done some more work on the combing.

    Hello @smartavionics

    With friends help I finally had the Cura with you modifications working on Linux.
    If you like you could share your Cura archives with your last "Combing" work.

     

    Thanks

    Hello @amagro, sorry for the delay, new archive available now. I have been seeing some crashes when starting cura so maybe there's a problem with the current master branch? Anyway, once up and running it seems to work OK.
