If you don't have a fancy-schmancy printer that tracks filament usage and warns you if you don't have enough filament left on the currently-loaded spool to complete the print, this is how you know. You can even double-check while it's printing, like I do in this video.

This is why you should always keep a kitchen scale and one empty spool of all the filament brands you use.

Low tech but useful. I figured I'd share.

I just check it every hour or two and stop drying when it stops getting lighter. I usually see an 8-10g drop after drying a new 1kg spool of PETG.

Interesting. I'll have to try the reverse experiment: I have a roll of TPE that's been drying in the dryer for at least 3 weeks. I'll take it out and see how fast it'll reabsorbs water.

Very cool idea! Please share your results once you have done it :)
