I own Simplify 3D, but pretty much never use it. 2 years ago I used to create some gcode of a model, and I'm been printing that model over an over ever since. Now I have updated my model slightly and there seems to be a sort of banding issue.The banding that you see in the pic here is only on the one side of the model. It is very subtle, but if my run my finger across it, I can feel that the bands are areas where the surface of the model is pressed in ever so slightly.
Does anyone know what might be causing this?
