Filament school (for me)

[mrehmus]

Couple of new to me thoughts/actions:
1. When I switch from a high temperature filament to, say, PLA, I now swap out the nozzle and PTFE tube I used with the high temperature filament because if I get the nozzle hot enough to melt the high temp filament so I can push it out of the nozzle with the PLA, the PLA will melt back up into the tube and jam it when I attempt to print. I've ruined a few tubes with over-temperature.
2. Here in Northern California, even in rainy season, the humidity stays fairly low and very low in the summer months. Not knowing how much moisture is absorbed by these filaments, I keep them in the clothing bags that are sealed and the air evacuated with a vacuum. The desiccant bags are sealed in too. These vacuum bags are only $4 or so from Harbor Freight here in the U.S. I imagine they can be found in other locations as well (the bags, not HF).

That is a good idea and sounds inexpensive. I have used weather tight containers in the past to store filaments. like this one -> https://www.walmart.com/ip/74-qt-Weathe ... 3=&veh=sem

For filaments like Nylon that are hygroscopic, it is better to have double protection.
