/diy/ - Do It Yourself

I'm at my wit's end here. Trying to print nylon and have had the heat break, not the nozzle - the HEAT BREAK clog FOUR times. WTF is going on? I'm printing at the recommended temperature and speeds and my printer handles everything else just fine. I can't imagine what would lead to the nozzle being clear but it jamming at the heat break.

Everything that I've seen says that nylon should have little to no smell when printing. I got pic related recently and when I started using it, it smelled very stale. I don't know how else to describe it other than when you open some chips or rice snacks that are *extremely* past their expiration date, that sharp, weird smell they have. It smells fine when it's cold. What's going on?
