Slicing creating holes in print

Posted · Slicing creating holes in print

I have a model that does not have any gaps in the surfaces, but once I slice it, there are holes created. They occur where two surfaces meet, essentially the model is a human figure under a cloak. So where the cloak rests on the arms a hole is formed rather than closing the surface. Is there a setting I should be changing to avoid it functioning like this? I have to use 15.04 since I have a M3D printer and use the Cura Engine in Octoprint.
Any advice/assistance is appreciated

    Just thicken the areas that are slicing as holes in the model itself. Walls need to be at least 1.5 (really low end) to 2 times the width of the nozzle to be properly recognized.

    I had the same issue that you are having. The gaps (for me) disappeared after disabling ‘Enable Coasting’. I think it may just have been poorly tuned coasting values.
