Hello All! I just got a spool of Bambu PETG-CF and tried to print a bench with the stock filament profile. This is what I get. I dried it overnight at 50c and got the same result. Thoughts? I appreciate any help you can provide.
50°C may just be too little depending on duration. Drying times extend significantly at lower temps.

Thanks @EnoTheThracian, I was worried about that. I have this EIBOS dryer, which I regret buying, as it can overheat the bottom of spools, so I usually set it lower, but run it for longer. I’ve upped the extruder temp to 265 and slowed it down, and it got much better. I’m trying now even slower. I wish there was a setting in BS to scale all speeds. I’m trying again, reduciing the flow from 11.5 default to 7 mm3/s to see if that helps. It’s a shame the RFID provided filament profile does not work out of the box. One of the reasons I like the Bambu ecosystem. Thanks again!

Mhm, the dryer does not look so bad. At least as long as the circulation actually works as intended. But the drying times stated there are a far cry from Bambu recommends (and from my own experiences which are closer to the Bambu times).
I am unfortunately not so experienced with PETG-CF. With PETG Basic, the profiles were very far off and the stuff printed much better with Generic PETG settings (in particular speeds and cooling settings). Maybe that is where you want to start?
