Pros & Cons
Bambu Lab A1 Combo
+AMS Lite ships in the box, not as a $75 upsell
+Bambu Studio slices and sends in under a minute
+500mm/s speed that actually holds up at 0.2mm layers
+Auto bed leveling runs in 90 seconds, not 10 minutes
−Open frame means ABS is borderline without an enclosure
−AMS Lite tops out at 4 colors; want more, buy a different system
−You're locked into Bambu Studio for the best experience
Elegoo Neptune 4 Max
+420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
+Direct drive on a bed this large is unusual and useful for flexible materials
+Klipper gives you full control to tune speed and acceleration for the mass of this bed
+Prints full armor breastplates in a single run
−Open frame at this scale means ABS warping will ruin prints without serious prep
−The sheer footprint means a dedicated table minimum; don't try to share desk space
−Slower effective speeds on a 420mm heated bed: physics wins eventually
