In May 2023, Elegoo announced its first high-speed 3D printer with Klipper firmware, named Neptune 4 Pro. After four months, they announced two new members of the N4 series named Plus and Max. The Neptune 4 Plus and Neptune 4 Max not only inherit the great features of the original Neptune 4 Pro but also get some significant improvements besides the large build volume.
The bigger build volume requires more heating power. The N4Pro has a 225x225mm print bed with 100+150W heating element, the N4Plus 320x320mm with 320W, respectively the N4Max 420x420mm 320W. All three models of the Neptune 4 family feature 121-point auto bed leveling with manual adjustment.
To handle higher temperatures and more complex filaments such as carbon fiber and ABS, the nozzle and the throat pipe of the N4 Plus and Max have also been upgraded from the N4 Pro. They adopt an all-titanium alloy heat tube and extended hot end with a 60W ceramic heating element.

In the table below, I compared the most important specs of the Neptune 4 family. Besides the bigger build volume, the newly announced N4 Plus and N4 Max feature WiFi connectivity, improved nozzle design, and a more powerful bed heating element.

WTF, all Neptune 4 models are sold out on elegoo.com!
I sold my N4Max and purchased the smaller N4Pro. The MAX is too lazy for small prints!
Which Neptune 4 has the largest print area?
The Neptune 4 range is very disappointing compared to series 3! Elegoo should do a better quality check before sending them out…
I have both, N3 Max and now the N4 Max.
The 3 Max worked out of the, but slowly.
The 4 Max needs more precise settings to make it work.
The N4 series has Klipper as its operating system, the 3 Max Marlin which is a big advantage!!!
What’s the difference between the Neptune 4 and 4 Pro?
The two spec pages on Elegoo.com look identical…
I have the N4 Pro and N4 Max since November 2023. Both are great machines, but most of the prefer the smaller Plus. It heats up faster and it is less noise. I would recommend the Max only if you print big models all the time.
Only the Neptune 4 Plus and Max runs on Klipper?
Pro comes with it
Wish I could afford at least the Neptune 4 plus :(. I read many good things about Klipper firmware running 3d machines not just elegoo
I was able to order a n4 ma yesterday, if you have problems keep refreshing!
