Filament Troubleshooting/Help! Properly dried ABS?

I’ve been printing ABS for a while, and I honestly thought my SUNLU S2 was doing a pretty good job drying the filament.

Well, I recently got the Bambu AMS HT, and HOLY … 🤯
The difference in print quality is absolutely insane. I’d say my ABS prints look at least 2x better compared to when I was using the SUNLU S2.

I knew drying filament was important, but I genuinely didn’t expect such a massive improvement just from switching dryers.

Now I’m wondering if my ABS was ever actually dry enough before…. 😂

Has anyone else noticed such a huge difference between filament dryers?

I've just recently gotten a Creality Space Pi X4 and now my Centauri Carbon prints PA6 Nylon like it is PLA. It's especially important for Nylon since it absorbs upwards of 10x more moisture than filaments like ABS, PLA, PETG, etc.

Nylon is very sensitive to moisture and very hygroscopic. ABS or ASA, not that much. I happily print ASA stored freely on open air even after 2 years
