No, no. I offered assistance.

What do I do with the white one? Put it in the last slot? Does the machine know when to use the white one as a support?

I don't use the support filament as I have enough filament that using a bit for a model or two here or there isn't a huge loss. However, you can use the Bambu Studio program and "paint" the support structures with that filament and it will use that instead of whatever normal filament you are using.

(Note on this, because these machines use NFC for the official bambu filaments, it might do it automatically. Don't count on that though and always double check.)

You can keep it in your AMS anywhere you like, but for those onboard print files, it typically uses AMS slot one.

What would you consider is your favorite filament to work with? I’m thinking of splurging on a set off ebay. But at the same time, are discount filaments ok?

I love Inland filaments because I'm close to a Microcenter and can go and physically look at them before purchasing them. If you aren't close to a Microcenter though, Inland filaments are Polymaker and eSun.

If you plan to get cheap filament, make sure you keep your bed as clean as you can because you want to rule that out immediately if there is an issue. I use Isopropyl alcohol before every print to remove any grease/oil/dust from the bed.

And do you use a special plate? People have mentioned golden ones that are easier to bend to pop out the build? Mine just scraped off fairly easy. And I’ve read to use hairspray or windex to make it easier to pop off later.

I use the standard PEI plate that comes with the machine. I allow the bed to cool off in the machine and then get the print off. Makes it much easier.

Controlling these printers is best done from a PC. Bambu Studio will give you the most options to control your prints. The Bambu Handy app works great as well but I find it limiting.
