I am printing a cylinder for a pistol (for cosplay). The bottom, print wise, of the cylinder has a ridge running around it. In this section, the % infill works fine- see picture, base layers on the right. Once the printer gets up a few layers and the OD of the piece gets a little smaller again, slicer is turning to solid infill for the rest of the piece- everything between the chambers and the OD is solid, instead of being the %; again, see picture, piece on the left.
Does anyone have an idea why this might be, and where I might find a setting I have missed? Or is this unavoidable?
Apologies for potato-quality photo.
