Have recently started printing with HIPS (Lulzbot’s filament) on a Taz5. Initial prints were horrible using recommended defaults until I turned off the cooling fan. Then quality was looking much better on objects that finished in points at the tips. When printing items with a flat top surface, am finding that the top layer is not laying down smooth and is peeling. Have seen this consistently across different items.
Any thoughts on what is causing this and how to correct?
