Pros & Cons
Bambu Lab P2S
+Quick-swap nozzle: no tools, no waiting for cool-down, no thread damage from hot-tightening
+1080p AI camera pauses the print when it detects layer failures, not just notifies you
+AMS 2 Pro dries filament while printing so you don't need a separate drybox for standard materials
+5-inch touchscreen is large enough to actually use without squinting at a 2-inch screen
−No LiDAR sensor: that capability is still exclusive to the X-series
−P1S owners have no trade-in path; the upgrade cost is the full $549
−Multi-color purges still waste filament; purge blocks help but don't fix the root issue
−The $799 Combo version gets close enough to the H2D's price that a comparison is warranted
Elegoo Neptune 4 Plus
+320×320×385mm at $299 — the largest build volume at this price point
+Stock Klipper means real input shaping, pressure advance, and Moonraker API access
+Direct-drive handles TPU and flexible filaments without clog risk
+Mainsail interface enables remote monitoring and print farm integration
+Dual Z-axis prevents gantry sag on tall prints
−Open-frame limits material compatibility — ABS/ASA require an enclosure
−500mm/s achievable but optimal quality typically at 200-300mm/s
−Large bed means longer homing and leveling cycles
−Elegoo's support and community is smaller than Creality's
