Advice on these listed printers
Bambu are excellent printers, but every printer has its issues. The ecosystem from Bambu is so closed down which personally drove me away. The ability for you to go on MakerWorld and grab the 3MF file and send it to your printer without any guesswork is very nice, which is probably why it’s such a g

Larger build plate printers
I’ve definitely been seeing some good things about it. If I could ever sell my Flsun s1 pro I’d maybe consider picking one up. I told myself “no more klipper printers” haha, but it’s just too tempting.

Just bought an S1
I have a S1 Pro and it has been pretty solid. I would highly recommend getting "high speed" filaments. I have had good luck with Sunlu's HS PLA and Elegoo's Rapid PETG with just default profiles (using OrcaSlicer). I haven't used other filament types outside of that. Be prepared for how loud it is.

FLSUN S1 - FREE
If I lived anywhere near Charlston, S.C. I'd be taking you up on your kind offer. I only have 2 (two) S1 Pro's in my farm but, they both work flawlessly. In fact, most of my FLsun printers are my go-to for fast turnaround. Of course I've also spent time with the machines ( and not just lazy plug & p
