Hi Greg Thanks for the advice, I'll try what you suggested. Slightly baffled though. If there is a one-layer gap between the support roof and the underside of the print, what actually happens there? Surely the underside will collapse on to the support roof. Or am I missing something? TD

I am new to 3D printing and still learning to use Cura. I am printing fairly large curved panels. I can get excellent quality on the top surface and on areas in contact with the plate, but the surface quality of the supported areas is poor. There is no surface finishing and occasional loose lines of material. I have the same settings for top and bottom, but bottom does not seem to mean underside. Is there anything I can do to improve the finish on the lower surfaces?
