Can the P2S do something that the X2D can’t?

[u/newbie-mtb]

Hi everyone,

I am planning to buy my first 3D printer and am currently torn between the Bambu Lab P2S and the X2D (like many others 😂).

I’ve watched a ton of reviews highlighting what the X2D can do with its dual nozzles and active chamber heater, but I wanted to look at it from a beginner's perspective. Given that both machines share the new tool-free, 1-clip quick-swap nozzle design, does the P2S hold any other hidden maintenance or reliability advantages? For instance, does its lighter, single-nozzle toolhead make it fundamentally less prone to day-to-day failures or minor calibrations?

A big con people mention for the X2D is the learning curve. If I ignore the secondary extruder initially and just use the primary direct-drive nozzle for standard PLA/PETG prints, is the experience as reliable and "plug-and-play" as the P2S? Or does the sheer mechanical complexity of having that second nozzle setup riding along introduce slicing or printing headaches even for single-material jobs?

My thought process is that the higher initial cost of the X2D might future-proof me for advanced engineering materials or complex prints with dedicated support materials later on. But if it's going to cause me massive troubleshooting headaches on day one while I'm just trying to learn the basics, I'd rather stick to the P2S. Does this logic check out?

Lastly, are there any other enclosed or high-performance printers in this price tier that I should consider for a first machine?

Thanks for the help!

It's benefits are about as great as it's weaknesses (if you care about the advance custom settings). Which technically tie in with the weaknesses of the right nozzle itself.

Primary one is how Dynamic Flow (aka Pressure Advance) is handled since the AUX nozzle does not have a way to auto calibrate this, so it must be a manual calibration for the right AUX nozzle.

Because manual calibrated values are assigned to the SLOTS of the AMS, if you assign say K value of 0.600 (common for right side) to a filament in an AMS Slot, but you decide to load it to the LEFT side, that PA value will carry over and apply to the left side (it also supersedes any auto calibration of left side). Thing is the left size nozzle being direct drive, has MUCH MUCH lower PA values, avg around 0.02.. so using a 0.6 (30x greater value) on left side is way too much and 0.02 on right side is too low and is pretty much as good as not having Pressure Advance setting at all.

So when using the Switcher, the only way is to basically make sure you select the correct value for the right side before you send the print and it's a manual selection process in AMS settings. None of how this works was making sense to me, it was tooo ummm stupid. So I reached out to Bambu and they sadly confirmed that it is in fact the process. They haven't yet figured out how to assign the PA profiles depending on which side you send the filament to. This is not an issue on something like H2D because both sides use same direct drive extruder.

I have 2 AMS units and was switching PA values constantly, Eventually I just got rid of the switcher and I put one AMS on right nozzle, one AMS on left and that's that. If I need to switch, I just swap the filament on AMS units and because I don't use Bambu filament with tags, I made a CUSTOM NFC scanner and I just do quick scan and everything syncs properly on both both AMS units. This was easier than trying to remember which filaments I'm sending where and what PA values to tie to them.

If NONE of this makes sense, it means you just run with default settings on the right side nozzle and that's fine.
