I hadn't considered it before but if you're getting water in the nozzle, it may indeed affect the feed rate.
Oh thanks for the tip! I could try this, since it's almost a full spool of filament.
It was laying around for over a couple of years. I had it put in a plastick sack, but gues it still could have collected moist over the years. It's pretty old too I guess...

But since it's almost a full spool I thought it would have been good for testing purposes. And not to spill anny new fillament this way.

But I noticed that at drips verry diffrently from new filament and that it pusches out some airbubles so now and then out of the nozzle. Don't see this with the other (new) filament.

So maybe this is giving me the errors I encounter.

Maybe calibrate the printer with fresh filament, and use this spool for prototyping or support. Trying to dehydrate is a good idea btw! I'm going to look for a food dehydrator too I guess, if it works well.
But for now placing it in a heat source will do well too? What temperatures should I use?

Water vaporizes at 100, and it's still way beneath the melting point of PLA. Or is it still too hot?
