I have a very thin walled model that prints fine with just a single perimeter and zero infill. For cosmetic reasons I want to make the program start and stop each layer on the inside. Since there is no infill and there is only a single perimeter printing I'm unable to figure out how to tell S3D to start and stop on the inside perimeter. This model has a crucial part located on the inside perimeter and labels on the outside. If it wasn't for the inside part I thought I could redo the model to be solid and just choose two perimeter walls but that would not work. Does anyone have any suggestions?
