What is the difference in prints with broad and narrow nosed nozzles? I have a 0.4mm broad-nosed nozzle that I’m experimenting with. I don’t recall where I got it (in a kit of nozzles I think). In some prints it provides a better surface layer than the narrow (similar to ironing without ironing). I would like to try a larger size (0.6 or 0.8) but cannot find one. Any ideas/recommendations?
