I am experiencing some issues with the slicer with some parts, the preview mode shows some gaps between layers in the preview, not sure if this is a image only issue or the printer will skip those layers when printing. I verify the part with Netfabb and is okay, also the Cura and Repetier software do not show the gaps
The image shows the mentioned gaps:

I have not tried to print yet since is a huge part and do not want to lose material and time
