Bought a Microswiss all metal hotend for my i3 Duplicator in order to experiment with Nylon etc. Since I didn’t plan on doing anything in large volumes i (stupidly) picked the 0.3 mm nozzle instead of standard 0.4mm one. Can’t get it to work, clogs up constantly whether it’s nylon, ABS or whatever. Physical installation is exactly by-the-book, but I’ve got no idea how to adjust the printer settings for the smaller nozzle. Anyone here have experience with this?
