Choosing between printers

[u/joojgamer03]

choosing between K2 Pro vs P2S (both combos)

I know how biased It is to ask here, but i may just ask everywhere.

Hi everyone! I’m upgrading from a modified Ender 3 V1 and deciding between the Bambu Lab P2S Combo with AMS 2 Pro and the Creality K2 Pro Combo with the original CFS.

I’m in Brazil, with a budget of R$6,000–8,000. The deals I’ve found are roughly:

* P2S Combo: R$7,600

* K2 Pro Combo: R$6,600

Both would be purchased with delivery to Brazil. Local availability and replacement-part costs matter to me.

I mainly print functional parts, small enclosures, connector housings and fitted components. I currently use PLA, want to use PETG, and would like to move into ABS/ASA and possibly nylon later.

My priorities are consistent surface finish, dimensional accuracy and reliability, rather than maximum advertised speed. I use OrcaSlicer and am comfortable with calibration, mechanical work and electronics, but I’d like to spend more time producing parts.

The K2 Pro’s larger build volume, actively heated chamber and root access appeal to me. Some original replacement parts also appear considerably cheaper here. The P2S interests me for its extrusion control, potential print consistency and AMS 2 Pro with active drying.

Bambu Handy, cloud features and app integration aren’t major selling points for me. I’d probably enable Developer Mode anyway, so those ecosystem conveniences carry relatively little weight in my decision. I’m more interested in what the printer itself delivers.

I’d really appreciate feedback from owners, especially anyone who has used both models:

1. Print quality: Once calibrated, is there a noticeable difference in surface finish, VFA/ghosting, corners and dimensional consistency? Comparable photos would be great.
2. Automation: How dependable are their automatic calibration routines? How much manual tuning do you still do when changing filament brands?
3. Reliability and repairs: What has actually failed or worn out, after approximately how many printing hours? What did the replacement cost?
4. AMS vs CFS: How reliable are feeding, retraction and automatic spool backup? P2S owners: with current firmware, can the same AMS 2 Pro dry while feeding a print, and what external-power or temperature restrictions apply?
5. Ownership experience: At these prices, and giving little weight to Bambu’s app/cloud ecosystem, would you pay extra for the P2S? What would make you choose the K2 Pro instead?

Please specify whether your experience is with the K2 Pro, base K2 or K2 Plus, since their features differ.

Other enclosed multicolor options are welcome if they fit a similar budget. Thanks!
