A while ago I bought a roll of transparent petg "the filament" by spectrum. Wonderful, it printed great, shiny, smooth. I loved it.

Then I took advantage of the promotion on the Bambu lab website "4 rolls are discounted + free shipping" and I bought their transparent petg.

I opened the vacuum bag, loaded immediately in the printer and it strings and pops. Settings are correct as the slicer has a dedicated profile for this roll.

Their website says "warning: dry before using" - they mean that it comes already too moist from the factory?

Unless the filament ships in a foil lined bag that's vacuum sealed with desiccant and an indicator card, you should assume it's wet.

Yeah I've had foil bags with dessicant be damp too. In my experience, if you're getting a deal on petg you probably need to dry it. That's probably why you got the deal.
