Kind of on the fence between the two. I’m coming from a Neptune 3 Pro running Klipper and using Orcaslicer so either option would be a definite upgrade.
I was pretty dead-set on getting the P1S since I’ve heard how good the Bambu printers are for so long now, but now reading into the issues with privacy a bit more I’m somewhat skeptical. I’m pretty handy with networking so I’m sure I could set up some firewall rules to exempt it from phoning home while allowing me to use their slicer, but it’s still a concern of mine.
I’ve seen a lot of people here recommend the Qidi Q2, which uses Klipper and has all the same features as the P1S otherwise, so I’m looking into that a bit too. The P1S with AMS is for sale at Microcenter near me for $550, but the Qidi Q2 is at $650 (albeit with a filament drier) plus whatever the shipping would be. Should I pick up the P1S this weekend like I was intending or hold out for a sale on the Q2?


I can say that my Q2 has been a joy to use. Every issue I’ve had with it so far has been user error. (Polymaker recommends no fans on their ASA. No, the ASA yearns for the fans, at least when your chamber is heated.)
And if you’re posting here, you probably want the option to print with high end engineering filaments. The P1S “can” print PA6CF, but you’re gonna need to upgrade it. And if you want to run something like PPACF? Gonna need even more mods.
The Q2 handles everything short of PEEK/PEI like a champ right out of the box.
But the Q2 is a brand new printer released three months ago, so don’t expect it to go on a good discount any time soon. But honestly, $650 isn’t a bad price for what you get. So yeah, I’d say go for the Q2 if you’re posting here. The Q2 is probably dollar for dollar the best guncad printer around.
Note: I can’t speak to how good the Box/Qidi AMS is. Because I ordered the Q2 Combo on week 1 and they still haven’t sent my box yet, apparently because they just released a new revision that fixes the big pain points of the design and they’re shipping that out instead of the v1.0 Box.
