PLA - recommendedmodified.ini (3.14 KB)
Every time I try and print object with sharp corners that are also overhangs, I get upward curling on the tips of the bends as soon as they are printed. Eventually it builds on itself and gets to a point where the nozzle will run over the large bump and I have to stop it. However, the side of the model that has the fan directly blowing on it turns out perfectly.
I am printing in PLA using the recommended fast settings on a TAZ4. I’ve tried changing the temperature, extrusion rate, speeds, and an external fan blowing on the print. Nothing seems to help it much.
