Buying call

Buy the Neptune 4 Pro if you want speed for less: early reviews praised its fast, precise printing, powerful direct-drive extruder, strong part cooling and dual Z-axis. Skip it if you want hands-off leveling, because the build plate needs manual input. Setup can be complex for beginners, and filament compatibility is limited.
