Speed Comparison: Neptune 3 Pro VS Neptune 4 Pro

With the Klipper motherboard and ARM 64-bit 1.5G main frequency quad-core processor to process and execute commands faster, Neptune 4 Pro can print at up to 500mm/s, allowing you to complete your print projects quickly and efficiently. With our pre-installed Klipper firmware, you can start printing right away without the hassle of firmware installation.

In addition, it supports input shaping, which helps eliminate artifacts and resonances on the model surface, and pressure advance, which helps predict nozzle pressure for more accurate and consistent extrusion and less filament ooze and blobbing.

Elegoo aways great brand. I have neptune 2S and Mars 2, both still working great, im looking foard to buy one Neptune 4, im whating till Brazil storage get one.

[johnnyBigFish]

Gracias por ayudar al chico con implementación nueva 💪🏼

[ryucosplayz]

Do you have cura profile for neptune 4 pro?

[jamesmarler]

Nozzle options. When will .6mm and hardened options be available?

[alucarddnd]

Opa, comprei uma e quando eu passo o arquivo do telefone para o microsd e coloco na impressora, ela carrega a barrinha vai esfriando e n faz nada. Alguém sabe oq pode ser ?

[minhthuantran]

Do you have any information on the release date of Neptune 4 Plus version with larger print size (320x320x400)?

[FunoXXX]

Will any of the parts from the neptune 4 pro be combinable with the neptune 3 pro? Maybe a hotend upgrade for the neptune 3 pro ;) ?? ^^

[ibrahimkesici]

plus and max versions models anytime soon?

[sumniumdoit]

where can i buy a nozzle for neptune 4 pro ?

[Worldofmikes]

Does it require rapid pla for faster printing speed i just bought neptune 4 max

[devampurohit]

What's the printing speed of the Neptune 3 pro??

[honda-sk]

i have the elegoo 3 max but can't find anywhere on the recommended speed for pla or petg

[BandRPlasticWorks]

Can't wait for that beefed up hot end!!!! Man thars going to be excellent #bandrplasticworks

[eyal_the_goat]

thanks for letting me know how bad my new 3d printer is...

[jsks]

The 6mm belt on the bed is really a shame.

The manufacturer seems to have chosen the marketing path for this model.
Adjusting the table is good.
A disposable heavy extruder is bad. Namely, the manufacturer made it disposable in pursuit of relief (unsuccessful, but more on that in the end). Gears are now original and unassembled, and it is impossible to buy them even in the official store)) The quality of the gears is not very good and, of course, they are NOT hot (like steel, not magnetic, it looks like stainless steel), so do not try to print composites.
At the same time, the plate of the table carriage remained steel (aluminum would be 20 grams lighter and not worse).
The nozzle heater is now also rare, in size 16*15*20 mm. So I still have to look for replacement socks. And the native sock crumbles after two weeks of work at 255 degrees.
The LED on the extruder is cool, but I feel it will die because of working in extreme thermal mode.
For the same reason, the inductive sensor of the auto-level of the table will also die. On Neptune 3, the same one died after several heats of the table to 85 degrees (the printer is in a passive thermal chamber). If you plan to print petg and abs, then buy a pair of spare NPN NC type. Do not try to find the original ones, they, like the gears, are also not in this store or in others))))
The nozzle radiator fan is now 3010 (instead of 4015), works at much higher speeds and will die sooner. Fortunately, if you file everything superfluous in the extruder, you can find a place for the cooler 4015.
Super blowing is not needed, because there is no question about the quality of printing at the stated speeds, so we have 4 unnecessary 4020 snails.
And I also decided to weigh the extruder assembly ... (in the advertising picture, the seller boasts of the extruder's weight of 291 grams, which is like a hundred grams less than Neptune3). And so. The extruder assembly actually weighs (!) 472 grams!
In general, there will be no long-term high-quality work at the maximum declared temperature characteristics, there is also no need to wait for speeds, and it is better to buy Neptune3, which is much cheaper and more maintainable.

The practical printing turned out to be somewhat better than I expected. The quality begins to be noticeably lost at speeds as much as 100 mm / s, which is very decent, despite all the jambs. The list of which I will probably continue.
The z-axis guides moving along the screw axes have a backlash of 2 millimeters. It must be eliminated, while avoiding the rigid attachment of these guides.
The system loads from 30 seconds to 3 minutes. The screen freezes very often when the buttons are pressed (usually for a couple of seconds, but sometimes up to 10 seconds). Occasionally, after pressing the buttons, the required action does not occur. It is impossible to press several different buttons in quick succession.
There is no menu for setting jerks and accelerations, and what the manufacturer has screwed up by default, it's scary to think, given what he "calculated and projected" print speeds. We'll have to manage this from the slicer.
An adjustable table is probably a good thing. but.
1. Two-stage calibration of the table at 121 points is too long, namely 10 minutes from start to restart to save the parameters (without a final reboot, the table map is not saved). About half a minute of this time is spent by the printer on unnecessary trips from the zero position to the same zero position. By the way, before printing, the printer also goes home twice for some reason.
2. the alignment interface is made completely incomprehensible. Visualized is not a logically obvious square of 11 × 11 points, but an incomprehensible rectangle of 6 × 11 points. the zero count on the z axis does not come from any particular angle and/or level, but floats all the time according to an incomprehensible algorithm and it takes a crazy amount of time to truly align the table! The first time it took me 5 hours of almost continuous attempts, the second time a few days later I managed in 3 hours.  This is a procedure that should take 15 minutes! moreover, I understood the process of achieving the result very vaguely and, even having achieved success, I cannot explain it (which means I cannot repeat it quickly).

It was only possible to understand that you need to turn in the corners where the value is minus counterclockwise, and where the value is positive - clockwise, but only in one corner and a little bit.
By the way, the Z-offset is reset when calibrating the table and needs to be reconfigured too.
3. The heating of the table and the extruder has really become more efficient.  However:
If you change the calibration temperatures of the nozzle and table through the standard settings, then instead of calibration, the printer hangs tightly after heating.
The settings of the preparatory temperatures of the table and the nozzle for the accelerated start of printing do not work here at all, since if you turn on the preheating of the table and the nozzle, then before printing the printer to turn on the heating of the table to the operating temperature... Attention!.. It will wait for the nozzle to cool down to 120 degrees))))
In general, compared to neptune3 pro, very ambivalent impressions. However, the disappointment from the shortcomings is gradually compensated by the fact that in fact the neptune 4 is about 1.5 times faster than the neptune 3 pro with the same print quality.

speed is not important,
quality is more important
