Elegoo Neptune 4 Pro: Unboxing, setup and first impressions

Unboxing and step-by-step setup of the Elegoo Neptune 4 Pro, as well as some first impressions and a test print.

Wife and I (early 30s) got stuck with the leveling process. Accidentally made the nozzle too close to the bed. We appreciate your videos and the time you take to go through each step! Looking forward to more content.

[@RAWGER526]

I just gave this to my wife for her birthday. It is our first 3D printer. Looks like I picked a good one. Nice and informative video😊

[@lostinspace2780]

I got my Neptune 4 and LOVE it! It is really a nice printer and easy to use. And with Klipper and network access, it makes a huge difference with printing without using USB drives or SD cards.

[@Ghost_writer_V]

You rock, bro thanks. It's going to really help with someone's first time set-up!

[@smchenry6438]

Ben, I just got the Neptune 4 Pro and being new to the 3D Printing arena, I appreciate the time and detail you put into this video. I am looking forward to checking out your next video on this printer!

[@MrLeonidas0001]

Phenomenal video my dude - mine is up & running 💯 out of the box in one day!

[@daveh1266]

What a breath of fresh air. I was looking at this printer as an upgrade from my ender 3 since I really started to find it very slow. Whenever I looked online so many reviews were either hastily done or just purely pessimistic. After have watched this video and the "after 200 hours" video I was confident that this printer would be a good upgrade for me, and I was right! I got mine yesterday and it's awesome. Can't wait to print more stuff! You definitely earned a sub from me. Thanks for taking the time to make this and the other videos, they're all excellent.

Loved your video man, thanks for uploading!

[@Shadow7777777777]

This is gold 😁 I just ordered mine and waiting for delivery. Your second video about review is also gold 😁 Authentic and all what is needed in comparison to all those big review videos with fireworks on yt 😆

[@BenMyhillJones]

Thanks for the feedback! I hope you enjoy your printer!

[@ricos727]

looking forward for more prints. I'm planning to buy the Neptune 4 as my first printer. loved your vid. keep it up

[@BenMyhillJones]

Thank you so much!

[@johnd7104]

Thanks Ben, this is a useful video. In particular, I found your instructions for levelling were easier to follow than the maker's video. I don't know why, but the sound of your voice seemed to trail off towards the end of a few sentences. Perhaps your young ears can hear it clearly, but my older ears struggle occasionally. Also, sometimes you would do something to the printer display so quickly that I could not work out what you had done without multiple replays. I remain impressed though and am about to look for the other videos you said you might do and hopefully have. Well done.

[@bryanfoster362]

Not gonna lie, one of my favorite features of the Nep 4 is the USB slot instead of that stinking microSD slot. As I get older, stuff gets smaller and harder for me to see and handle. The fast printing and stuff is just a nice bonus 😁

[@BenMyhillJones]

Yeah, the USB stick is a very overlooked feature. Not just for the printer but also slicing on the computer, having it all in one package is super handy!

[@PeterAgostiniJdcap26]

I agree

[@afilippidis]

Very nice presentation! I got into 3D printing with an Ender 3S1 Pro but will soon buy this one as well instead of upgrading my Ender with all needed stuff so to try reach such printing speeds!! Thank you for this video!

[@uknowman4561]

Look at that thing go. I love it!!! I need this.

[@menistro]

Hi Ben. First of all thank you for the great video. I really loved how you showed us the initial process of assembly and leveling of the printer. I am looking forward to receive mine in some days and start in the 3D printing world, as I work with regular printers and I want to expand my knowledge with the 3D version of them. I have couple questions regarding the use of the grease and the noise. We saw on the video you used it in the rails where the bearings move but not on the Z Axis rail. Is there a particular reason? About the noise, you mention the airflow of the Silent mode is sufficient but also we could see the bed was hot when you retrieved the test print. Would you recommend it to use overnight or while working from home? Again thank you very much for this awesome video! Keep up with the great work 😊

[@BenMyhillJones]

Thanks! I am glad you found it useful. I added grease (a bit too much) to the X and Y axis because they use linear rods, unlike most other 3d printers that use rubber belts and wheels. Because the toolhead and bed move quite quickly across the rails, and use metal on metal, the metal wheels need to be lubricated as not to cause damage through grinding and friction. The Z axis does need to be lubricated, just not as often, because it uses a screw and travels much slower compared to the other axes, it needs it less. You should clean and grease the z axis leadscrews around once every 3 months (there are plenty of videos documenting this. The large part cooling fan located on the back of the X axis is not mandatory, because the printer has two part cooling fans located in the toolhead which help cool the plastic. If you are printing something with lots of details or overhangs, using the large fan on the back will increase print quality significantly. Without the use of fans, a print will be stronger, because each layer is more fused together. With lots of cooling, the print will look much nicer, but will not have as good layer adhesion (still good for almost everything). It all comes down to the specific print. The bed is supposed to remain hot throughout the entire printing process, it helps keep the filament stuck to the bed, if the bed was cold then as the filament cooled it would shrink slightly and cause warping around the corners which can lead to print failure. In regards to printing at night or when you are around it, the answer is, it depends. I would stay far away from filaments like ABS, ASA and nylon when printing without extensive ventilation. When printing PLA, it still emits VOCs when printing, so cracking open a window and ventilating air out is recommended. I would not sleep with it running or spend many hours next to it without ventilation or some kind of filter. If it is in another room while you sleep it doesn't really matter as long as the sound doesn't bother you. Good luck with your 3D printer!

[@menistro]

@@BenMyhillJones Awesome mate! Thank you very much for the explanation. I believe in the future I will have a small cabinet to place it inside, and maybe (depends on cost) soundproofing it a bit. About the maintenance, for sure will take a good care. Thanks a lot again for the video and the quick answer! Happy New Year and best wishes to you and your people!

[@jackgamble6120]

Hi Ben, great video! Three questions for you (if you have time to answer of course): 1) The Neptune 3 Pro is available for $209 and the Neptune 4 Pro is available for $259...are the differences enough to buy the Neptune 4? 2) The bed leveling system seems to be different between the two...which is more automated or better? 3) Finally, will you be doing a Neptune 3 Pro video or a video about Neptune 4 versus Neptune Pro 3 video? Thanks again for a great video!

[@VicMorrowind]

Sorry for another question. Some printers is see can be rooted to get full klipper support. Can this neptune 4 be rooted or does it already have full version of klipper?

[@MARCKJANSEN7721]

Exelente ! seria buena idea hicieras un video con especificaciones de uso de las boquillas ,asi como el uso extendido de Klipper , incluso de como hacerla funcionar con un acelerometro como ya lo has comentado para sacarle aun mas provecho a este firmware, actualmente trabajo con una ellegoo neptune 3 plus y acabo de pedir esta nueva neptune 4pro , saludos desde la gran TENOCHTITLAN!

[@АнатолийСоломонов-ж2п]

Is it necessary to glue it?

[@frankdearr2772]

Great review, thanks 👍

[@uncannyrecovery3980]

With auto leveling, do you have to still use the paper trick? I have a vyper, and I never used paper after the auto leveling. Fantastic video btw! Probably getting a N4pro soon!

[@stanleyhoptroff]

yes. hope you have a good time with your printer

[@jackgamble6120]

I heard that the x and y axis are misaligned on all Neptune 4 series by 2%, which is a lot... no fixable solution for it. In other words, if a circle or cylinder is printed...it will not be round...instead it will be slightly oval. This becomes a problem when making items that have round gears printed within an item. How true is this and is there a fix for this on the Neptune 4 series?

[@VicMorrowind]

fantastic vid thank you

[@BenMyhillJones]

Thanks!

[@PeterAgostiniJdcap26]

what is the fastest speed you used so far Ben ?

[@tayfunates5191]

Hi bro, i really wanna buy this printer but i have some doubts. Have you any problems with this printer? I have ender3 s1 but its too slow for me.

[@BenMyhillJones]

My first printer was an Ender 3 V2, and I can certainly relate to the slow speeds. From what I have found it is a very good printer for the price, if you value speed. There are so many quality of life improvements and I have not had to troubleshoot anything, I set it up and it has worked flawlessly. That being said, it is incredibly loud, even when the fans are off. This goes for any high speed printer. There certainly is a trade off with the high speeds. I have also found that at much higher speeds (upwards of 250mm/s) the print quality has deteriorated slightly. For functional prints, it works great at high speeds. When turned down to slower speeds (between 150 and 200mm/s) print quality has been amazing, better than that of my Neptune 3 Pro. It is a very capable machine, and when tuned more it can deliver incredible results at fast speeds. It is still very capable at higher speeds and the print quality at 350mm/s is still better than what I could ever get on my Ender 3V2.

[@tayfunates5191]

@@BenMyhillJones thank you bro i will order quickly 😅😅

[@ROGERTHATRADIO]

When do I need to apply thermal paste?

[@PeterAgostiniJdcap26]

How do you access it through internet access where do you go on website? Thanks Ben

[@BenMyhillJones]

If you go through the printer about settings on the touchscreen, you will find an IP address. Enter it into your browser and it will take you to the Fluidd dashboard for web control.

[@PeterAgostiniJdcap26]

@@BenMyhillJones thank you Ben .. I keep it simple for now . I posted your nozzle repair 3 times on facebook Elegoo .. really value your knowledge Ty 👍🏻

[@weilam03]

the boxes keep getting bigger and bigger lol. i started with the 2s, got the 3pro. i might dkip this to see what they fo next with maybe corexy. not a fan of proprietary nozzles especially with the 300 degree capability. the stock nozzle wont be able to print carbon fiber filled filament

[@BenMyhillJones]

That is definitely one of my biggest complaints, Not being able to print anything abrasive long term is not great. I did find some 3rd party sellers that make hardened steel nozzles, and hardened steel CHT nozzles. I ordered some and will be testing them soon.

[@BenMyhillJones]

@@BasOlthoff I purchased a variety off of a seller on Aliexpress, there are two main ones. They are probably pretty similar in quality, and for me the quality has been really good. The CHT nozzles are also worth a try. Just search for Elegoo Neptune 4 Pro nozzles and you should see a few results.

[@guardiandragons3633]

Ok for 1. Where is the normal and sport setting? Because mine is running its first print and there is nothing in the keypad settings.

[@BenMyhillJones]

When printing, if you go to the speed settings, you can go under fans and control it there.

[@adrianfidler1169]

Dude that's WAY TO MUCH greese on those rails. A blob on the middle once in a while will be plenty unless you want your rail to pickup dust etc.

[@BenMyhillJones]

Thanks for the feedback! I totally agree. later in the video I mention I added too much grease. Since then I wiped a bunch of it off.

[@carylaue191]

I cannot believe that ELEGOO release what appears to be a brilliant machine and yet still being fitted with these ridiculous and useless POM wheels and WORSE - the bed adjusting wheels and springs !!! What does it take for ELEGOO to recognise the far more beneficial use of Linear Rails and a fixed bed and sure, charge us a few dollars more but make us - the people who pay your wages - more likely to buy your products !!!!
