  1. You are on the ball my friend. Is it just the most recent .exe file? In this case “Cura-mb-master-win64-20191209.exe”? Will it just install as any other program would? Anything I should be aware of?
  2. Thank you Burtoogle, The model is of a high resolution. I assumed it was a bug of some kind. I did play with the resolution settings in Cura a bit and had the same concern that you mentioned in that the details of the model might get lost (which I didn’t really want to happen). The image that you uploaded is what I am seeking to accomplish when I slice the model in Cura. I went to that link (thank you for providing it), read the README.md file. I saw the “20190823 - Upstream changes + bug fixes (polygon simplification, duplicated prime tower brim)” Part. That might be what you were referring to in your latest post. To be brutally honest I am not sure what I am looking at or looking for in that link. Are these official development releases from Cura? Like betas for testing? Are they plugins? Or are they personal Cura releases with your own additions/tweaks? Could I access these through Cura’s official github page? How would I choose the proper thing to install? Would I have to uninstall the Cura 4.4 version that I am currently using? Would it affect future official updates? You seem to be a very active and helpful member on this site and I appreciate all that you have done to help me and I am seeking a quick resolution so that I can resume printing some holiday gifts for my friends and family but I am always a very cautious fellow when it comes to downloading unknown software and programs from an unknown Dropbox or Google Drive recommended by a stranger on a forum to which I am a new member. There are too many shady people out there these days. Not that you are one by any means, your activity on this forum shows that pretty clearly. In any case I suppose I am just looking for a quick safe fix to get back to printing. How do I determine what “Cura build” to try? Are they installed like any other program? Could I get your working version of Cura from that link? Will it work for my 64-bit Windows 10 PC? If possible is there an official Cura source I can access that Dropbox from? Could you point me in the right direction? Thanks again for all your help. Sincerely, Brian B.
  3. Hi again Burtoogle, I suppose I misunderstood your instructions. I opened the .stl file with Cura, verified that the profile I wanted to use to slice the model was selected, sliced the model, selected “Save to File”, Save as type: 3MF file (*.3mf), clicked “Save”. Then I zipped them up and uploaded them here. I did not File > Save as requested. My apologies. I have uploaded the single .3mf project file. Thank you again for your assistance. Brian B. P.S. I have tried many different settings to get the models to slice correctly. Did you try to slice any of the .stl files with your own configuration to see if it converted it to a polygon? A few other people online are having the same problem that I am. In any case, thank you for taking the time to help. I look forward to your reply. CCR10S_test002-blank-background.8min-thickness.3mf
  4. I have been troubleshooting all day with no success. I am still having the problem in Cura. I generated a few test files to troubleshoot with which I will upload along with the .3mf files. If you look at these test files Cura does a pretty decent job slicing the bottom of the frame correctly (round) but on the top of the frame it still slices it as a sort of polygon shape. I hope it helps. Thank you for taking the time to help. I appreciate it. Brian B. P.S. I can get these .STLs to slice properly with the PrusaSlicer but the PrusaSlicer doesn’t offer some of the settings/features that Cura offers and that I am wanting to use for these prints, such as Combing. Again, thank you for your help. cura-tests-01-04-curved-to-poly-bug-3mf-files.zip cura-tests-01-04-curved-to-poly-bug-stl-files.zip
  5. Hello Ultimaker Cura Community, I want to start out by saying that I really really really like to use Cura as my slicer. The features it provides makes slicing as smooth and streamlined as possible. Recently however I have been making custom Christmas gifts for friends and family members and have seemed to hit a snag that Cura is having a lot of trouble with. At first, I thought it was the model itself but after extensive troubleshooting it would seem that the fault lies with Cura not slicing the model properly. ANY help would be greatly appreciated. Here is the problem… I have multiple models that contain a smooth rounded face. This curvature has a Radius equal to about 80% if I am not mistaken). When I import the model into Cura it appears as it should. Smooth, round, clean and beautiful. Once I slice the model however Cura for some reason converts that smooth rounded face into a polygonal shape. Which wouldn’t be horrible if it did it for the whole model. But for some reason it seems to slice the bottom of the model correctly and then not so correctly else ware. I have done my best to solve this problem on my own but have concluded that it is a problem with the Cura Slicer. Here is a list of some of the troubleshooting I have performed: 1. Printed multiple models (different models with the same radius/curve). 2. Updated Cura to the latest version. 3. Verified that these abnormalities were showing after slicing the model in Cura ruling out hardware issues with the printer (CR10S). 4. Imported the models into three different 3D software programs to verify that the models where not the issue. 5. Verified that the model(s) imported into Cura correctly. Cura shows and displays the model correctly until the model is Sliced. 6. Verified the curved round edge of model turns into a polygonal shaped after slicing. This happens on any smooth area of the model. Rough areas seem to slice correctly. 7. Tried adjusting the resolution under the advanced/experimental settings in Cura. 8. A few other users within the Lithophanemaker Community on Facebook had the exact same issue, which rules out a problem with my specific Cura installation. 9. Downloaded, installed and configured the PrusaSlicer to work with my (CR10S) which was able to Slice the model without issue. Any suggestions as to how I can resolve this problem? I have spent a lot of time and love dialing in my Cura settings for my printer and would rather not have to configure another slicer program. Any and all help is appreciated. Brian B.
