Pros & Cons
Neptune 4 Pro

- +Klipper pre-installed with decent out-of-box profiles
- +500mm/s sustained prints well with stock settings
- −Early units shipped with firmware bugs that needed patching
- −Elegoo's support community is a fraction of Creality's size
SV08
- +Voron 2.4 kinematics for less than the $1,000+ in DIY parts and time
- +350x350x400mm bed handles nearly anything without splitting prints
- +700mm/s is a real number that the machine hits in practice with tuning
- −Out-of-box calibration takes several hours for first-timers
- −QC is inconsistent between batches: some units are great, some need work
Buy these with it
A printer does nothing without these. Grab them in the same order.
- ELEGOO PLA filament, 1kgThe easy filament to start on. Prints at low temperatures and warps less.
- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
