  1. Interestingly those settings are also creating a spiral with the current Cura build. I'm trying to figure out now what was causing my slicing to fail previously. It might be that I had retraction enabled. I was surprised to find that spiral slicing didn't override the retraction option. Thanks again for your help. I'm hoping Cura will solve a couple of issues I had with spiral slicing in Simplify. Sometimes I would get a really prominent Z seam even though the motion was spiral. It seems that there is a slight pause or a slowdown once per loop without a corresponding pause in flow. I also occasionally run into models that slice with a periodic XY offset that follows a meandering Z line. In both cases the artifacts appear wherever the initial loops began. So far so good with Cura.
  2. That seems to be the issue. My test is spiralizing properly. Thanks for your help.
  3. Thanks for clarifying. Unless the problem now is with the preview, that series of choices does not seem to solve the issue. Here is what I get when slicing a test cylinder with that fork, Normal, and Smooth: You can see how the layer is clearly stepped up. I'll go ahead and print the file to see if it is a preview issue, but I was getting clearly stepped models with starts and stops using those settings and the current build.
  4. I read the whole thread. I found no solution. I tried the smartavionics version if that is what you are referring to. Is there something I'm missing?
  5. I'm having the same issue with Cura failing to slice in spiral mode regardless of the settings or models that I give it. I've long been using Simplify3D for its ability to spiralize effectively but I thought I would give Cura another look since S3D is giving me some artifacts with some of my models. It sounds like the consensus is that spiral slicing is broken in Cura? I've tried with both manifold models and surface models, and with surface mode in both "Surface" and "Normal" settings. I've also tried with and without the "Smooth Spiralize Contours." Nothing seems to work. I'm getting discrete layer steps regardless. Is there an older version of Cura that is known to work properly with spiral slicing?
