Pros & Cons
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
- −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
SV08
- +Voron 2.4 kinematics at $479 instead of $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.
