Cura slicer does not appear to handle very fine grids and lines correctly. I have searched the site, but cannot find anything directly relevant. I have contacted Ultimaker support n the UK, but they were unable to help and suggested using this forum. I have attached the offending stl file (please reduce to 50%, as it was designed twice life size), and a photograph of the issue. Cure slicer appears to jump corners randomly, and to fill in small grids unnecessarily. I will admit that I find many of the setting confusing, so the problem may be a setting, but I have been using my current 'fine' configuration with few problems in the past year.
I would be grateful for advice on how to get round this issue, or to report it as a bug in the algorithms.
Repeating this on the CraftWare slicer produces better and usable, though also not perfect results.
I am also having problems with the slicer handling two halves of an 'identical' design differently, and ignoring supports on one side, but I will raise that as a different topic, should this request for help prove successful.
Many thanks
