[quote=“ziglu5”] Are you unloading filament after each print[/quote]Nope. I’m unloading only to change the color.
[quote=“ziglu5”]How many days can I have it loaded into the printer. [/quote]ABS can stay indefinitely.
PLA too but it tends to break (if it’s too cool, if there’s too much humidity) It also vary with the brand : some lower quality filaments are very brittle. I have a spool of Polymakr PLA loaded for month now and it never broke.
Leaving the filament loaded doesn’t clog the nozzle. Too much heat do.
