I say having spent the last weekish frustrated that my printer seemed to just be awful at making prints with even loose tolerances all the sudden.

I was using filament that had been left out a month or two, so not long at all, so I thought. Killed the rest of the spool trying to tune things, prints worked perfectly when I got a new spool out.

Goddamnit.

    If it makes you feel better, the very same thing happened to me a few weeks ago. Got it loaded, adjusted flow rate, temps, loaded, and the filament proceeded to crack apart. Multiple places.

    Checked date, two years old. Oops.

      I have filament that is now more than 5 years old and it still prints fine. But I also had 5 year old filament that printed fine at the outside of the spool, but cracked at the inner 1/3 of the spool (just a day later)

    Needed this. Thanks.

    Does it also mean that even if I bought a prusa mk4 and used old filament, it would shit the bed?

      I think that depends on how it was stored and if you have a way to dry it. I know some people will heat filament or use dessicant packs in an airtight container to restore old filament, but I’m not sure how effective those are since I haven’t tried any of them before.

      Definitely would suggest getting new sealed filament for anything that requires tighter tolerances or parts that need to fit together though. The filament I had wasn’t breaking or making things look terrible, but it made the filament expand as the moisture boiled off in it, so the parts were all a tiny bit too big so no parts would fit together properly.

    Get a plastic storage container that seals and some desiccant.
    I literally would not be able to print TPU without it, and it really helps stringing and lines on my PLA prints too.

    I was trying to print some parts and was having a terrible time, couldn’t get anything to stick to the bed and couldn’t get anything started. I leveled my bed a couple times, checked and rechecked my z offset just couldn’t get a print started. Turns out it was just the two rolls of filament I was trying are just bad filament or something. I switched to a different spool of pla and it immediately started printing fine.
