Pros & Cons
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
Kingroon KP3S Pro V2
+Linear rails at $159 is genuinely unusual: this feature normally costs $300+
+Direct drive handles TPU without the feeding nightmares of a Bowden setup
+Compact footprint fits on a shelf without dedicating a full desk to it
−200mm cube limits what you can print in one go
−Kingroon's community is small: if something breaks, you're mostly solving it alone
−Firmware is functional but hasn't had meaningful updates in a while
