does it work on ps5 games or is it possible for it too
It does but i believe the motion stuff isn’t compatible with every game.
Hey, is there anything i need to change in the printer config? Like, is the head- position identical to the original? Nice work anyway ! Got both kits sitting at my printer, going to start tomorrow 😅🤙🥳
Nope! After you install it, you don’t need to worry about changing anything in the configuration.
Emudeck doesn’t work on my legion
What is wrong? Did you follow step by step? Have to provide more details for me to help.
Sent it back, bed warped and was not levelable after 3 weeks. back 2/3 of bed was fine front 1/3 print head would drag on the bed.
What printer did you decide to try after? Hope you got better results. It sucks with 3D printers that every machine is so different. You’ll get people praise the Bambu labs printers and other say they are hot garbage too.
Went with Bambu Lab A1 combo. Has been great so far.
At least you found one you like!
Your first layer test print is only supposed to be one layer, you have 2, that will mask any errors typically showing up on the first layer.
Thank you for the remark. I honestly didn’t notice. I will keep that in mind for next time!
Where did u get that pey plate at 8:19 ? the one with special pattern ?
Right off Amazon! Just make sure you get the right size sheet. The last thing you wanna do is get one too big or small.
Is this fully functional by bluetooth on a PC because I have no idea what this means "D-input is defaut mode, X-input mode is available for USB C connection only(2.5M USB C cable included)." from the amazon description. I have too many wires as is and I mainly play star citizen so I need the touch pad to use as mouse scroll, otherwise I will be stuck in the elevators.
D input basically tells the pc it’s an PlayStation controller. X input tells the pc it’s an Xbox controller. And it does work via Bluetooth.
7 months ago I commented on your video that my Rog Ally had gotten wet, today I reconnected it after having forgotten it and what a surprise it turned on again and everything works great, I only have one problem, the touchID power button overheats to a very high temperature, what do you recommend? Do I have to change just that part?
I believe that part can be replaced. Give there replacement part site a visit and see if it’s available. But I would open it up and make sure you have no corrosion build up anywhere.
I have an axis rails but not belt. Is there a place I can buy just the belt part as shown here?
The Neptune 4 plus uses 6mm GT2 timing belts, which can be found on Amazon fairly priced. If you are talking about the parts used in TBStron3ds kits, I don’t believe you can order the parts separately. But shoot them an email and maybe they can sen you just the parts and no rails.
Can u make 20cm big pls
Send me all the filament and I’ll make a life sized one 😂
@@EdsTechTalk94 what is filament
Filament is the stuff that is used for 3D printing. It comes in different types such as PLA, PETG, ABS and many more. Some have carbon fiber infused in the plastic to make it even stronger.
Does this controller reconnect to bluetooth on pc? Or do you uave to readd it every time?
I figure it would just behave as a normal Bluetooth device. I can try later today but I also recommend not using Bluetooth as it increases the input latency.
So the Steam input options aren't required?
No they are not needed as long as you set it up as the device you’re using like the Ally or Legion Go.
@@EdsTechTalk94 Also how do you open the emulator settings during play to tinker with resolution etc? Thanx
That depends on what emulator you are using. You’ll probably have to google that one 😅
can you use kontrol freaks on it ?
I don’t see why not, the thumb sticks are the same size as the Xbox ones.
I have a question please do we need internet connection to use the disc drive after registering it
No you do not!
Which one do i order for the neptune 4 max thats the full kit?
Under the Elegoo products it should say Elegoo Neptune 4 MAX upgrade kit and then you have to add each kit (x, y, and z)
@EdsTechTalk94 oh OK thank You
would you recommend to change the rods to belt at the same time?
It wasn’t hard to swap the rods out for the belts after all the other mods. So if you wanted to wait I don’t think it will be that hard to put on.
Great videos, these helped me immensely. However at 0:45 you mention TBStron says they're ready to be installed with grease from the factory and that doesn't seem to be the case. Other videos and posts I've seen have said they need to be greased, and the grease they come with is more for corrosion protection. I installed them without adding grease and they are very dry now, waiting for some lithium grease and syringes to arrive tomorrow. You were right to clean and grease them yourself, I think everyone needs to go that before installing. That said, your videos were great and helpful. Thanks for posting!
Yea I thought just to be safe I would clean and grease them myself before installing them.
@@EdsTechTalk94 You definitely made the right call. Just sharing my experience for anyone considering skipping that step.
I was so enthusiastic to buy this printer model. After a month of use all hell begun... After a blob of death everything went pear shaped. I've got the replacement print head no doubt, but the next one couple of days later... I was so angry, I've just throw it to the bin... No replacement from this company. Since the installation and re-levelling of the latest pre-assembled extruder kit I was not able to print a single usable piece. As the latest repeated fails, I've checked the bed temp and found that: it is all over the place and some parts even 10C degree lower than the set level. I wasted countless hours and countless filament reels with this junk of a printer. Not happy at all! Wouldn't ever buy another elegoo in any shape or form.
Sorry you had a bad experience with it. But mine is still running strong. Don’t get me wrong, it has had a lot less run time compared to when I first got it but it’s still running strong.
I agree. Go Bambu!

I was considering upgrading my N4P to linear rails but I've read how bad they are if you don't lube them constantly, otherwise they will perform worse than POM wheels. That really pulled me off this upgrade after seeing the barely noticeable differences. Nice video tough, we need more content for the N4P, which is by the far the best printer in the 300-350 USD range IMO. Before the N4P I had an Original ENder 3 for over 6 years and I only changed its POM wheels in the last 6th year in an attempt to improve the X axis jerkiness and ghosting that I was experiencing, only to find out that the issue was with the worn out belt gears instead. The POM wheels where still fine after all those years.
I found it helped with bed leveling the most, removing the pom wheels made it easier by eliminating one more factor. I turned the nut once and I could never get it back the same (taco bed).
I am doing all 4 update to my Neptune 4 max at the same time. It is harder than doing a single mod at a time. :( But I am getting there. Almost done, should finish today.
Oh man that sounds like a lot of fun! Glad it’s almost done! You’ll notice how much quieter it gets too! I was extremely happy with my Neptune 4 Plus after the mods too.
hows the print after all this mods , on mine i did apex extruder and Phaetus rapido mod and it made a world of diference
If I use the basic profile in orca slicer it works really well. It made the machine a lot quieter since it’s basically all belts now too. But I’m currently trying to improve the speed of print times while maintaining that same quality
@@EdsTechTalk94 if u need the mount for the apex extruder and paethus rapido just say , its a huge diference But iam now sub , iam waiting for the next video , big hug
The build seemed straight forward, there didn't seem to be directions on the steps to calibrate. I didn't get the WiFi to work, adding a Klipperscreen to the SX08 I could select the WiFi hotspot but it would not ask for the password, it would just start connecting without the password and fail, tried the wifi.cfg method, no luck and finally plugged a ethernet cable in but still failed to connect. Another Makerbase POS with fans trying to keep the overheated controller cool.
Sounds like a bad board if it won’t accept the WiFi info. I’d contact support for some help. I have no advice for you on this one sadly.
I’m stuck on the initial step “installing EmuDeck WE dependencies”. I’ve tried clicking both yes and no to the dns prompt. Anyone else having this issue?
it might be opening another window you are not seeing, and or once its done I believe you close the prompt and its continues
What retraction settings are you using
I believe.6
What retraction settings are you running
I believe .6 is what I have it set for. I have an older profile for my Neptune 4 Plus in the review video of it.
Great video! Does this increase the height of the machine and if so how much? I'm concerned about it still fitting inside my enclosure.
It does increase the height by 2.125 inches (2 1/8”).
@@EdsTechTalk94 Thank you!
was that a cg5 refrence
Sadly no, as I don’t even know who that is 😅
Pls answer me i have lenovo legion go when i in install the emudeck it all right except when i arrive to collecting drives name the drives doesnt appear at all and the app couldnt read my drives what i should do 😢😢
It doesn’t show any drives? Not even an SD card? Sounds like a hardware issue. Maybe try uninstalling and reinstalling
Just bought one and love it so far
Love this mic. Have one myself
Love the content. Great breakdown
Dim the background music a little maybe make your voice slightly louder but other than that pretty good video bud 👍 can see you having a decent channel with a good base.
Thanks for the feedback! Will consider all that when editing my next video!
I'm receiving the last of the upgrade kits from Tbstron3d tomorrow. I went to the thingiverse link for the locating guides, spacers, etc. The problem is, the downloads dont actually include the alignment tools shown in the pictures. Is there another location to where they might be? I did a little searching but so far turned up nothing. Geeat videos, btw. Looking forward to following along while destroying...er.. modifying my N4+!
Another video about Sovol…. And another one that fails to mention that they have zero customer service after you buy the unit. You did not pay for your unit and I see that it has been over two weeks since you sent Sovol a correspondence… And you have no response. Not a big surprise. I listen to one of these RUclips influencers and was stupid enough to buy an SV07+ based on their comments. The printer broke down in less than two months. It has been broken down for almost 3 months. I have a lot of worthless emails, but no parts or real support. Finally, on May 25 of 2024, they said they were shipping a new power supply. They provided a tracking number from USPS… The slowest shipping company in the United States. As of today, June 16 of 2024, USPS is still waiting for the power supply! Rest assured, if you are not a paid supporter of this company, you are not going to get any customer support after you spend your money. do you think for one second that they are making people wait three months for new printers??? I don’t think so… And I’m pretty sure you know better. Don’t drink the Kool-Aid and fall for the crap. Buy a Prusa or a bambu labs and you will be much happier… That’s what I did and I am back in business with a superior product that actually comes with customer service.
The rattling of that one Z belt is probably excessive lock-tite ooze which dried up on the belt. Clean it with some pure alcohol and you should be good to go
It’s been fixed but sovol sent a replacement part due to metal shavings appearing under that same pulley.
@@EdsTechTalk94 Alright, some other issue then after all... Glad it's been fixed
hell yeah
Now if I could just find a place to find some switch roms.
Google
It's a pity there is no comparison of the same prints before and after all these changes
To be fair, I could get an ender 3 straight out of the box. Tune it to perfection and get the same print quality as any other printer. The charts from the other axis proves it was able to help improve the acceleration in the input shaper. I’m still working on tuning my machine to share a profile over all.
@@EdsTechTalk94 A spot-on remark. 👍 Thank you for the response.
Anytime!
I just ordered one from the UK site of Elegoo, It was on sale now and there is still 4 days of that sale ongoing! It cost me £283.99p which is a saving on the non sale price here of £81.00p Since it is a UK site I don't pay import fees or shipping those are zero. It should be delivered between 3 to 7 days. It will be joining the other 3D printers I already have of the Neptune 3 & the Neptune 3 Max and the Elegoo Saturn 2 4K Resin printer and the Qidi X-Plus-3 core xy klipper printer. I dismantle the two other printers I have and pack them back in their original boxes for storing as they been a pain over the last 6 months leveling problems etc. even though I upgraded them over a time to be better printers. So the work top space those two ( FLSUN QQ-S Pro Delta & the Aquila printer ) can be freed up for the new Neptune 4 Plus. I am hoping to find out how to do klipper control of the Neptune 3 & 3 Max using the BTT Pad 7 I brought? No videos seen to do that for us non klipper coders sofar found sadly? 🤔
Man you have an army of printers. I still have yet to get a resin printer. As for getting the neptunes to work with the BTT pad, I don’t know if it’s just plug and play. But I do know they can run Klipper, I think it requires a new mmc or a dedicated raspberry pi.
@@EdsTechTalk94 Hi, the BTT Pad 7 has Klipper system already installed on there, and they say run 4 printers at once. But it is the set up of how to do that is my problem? The Saturn 2 resin printer can do great detailed prints at 4 K and I have the wash & cure XS system too, My only problem is, the waste water from the washing! I use water washable resin due to the high cost here of the IPA normally used to wash prints. The problem even with the wash water is simple! Not having the strong sunlight here in good old UK to set the resin in the water after the printing, as being toxic it can't go down the toilet or drains etc. I had to store it in sealed containers, now have 20 liters stored. the last two years we have had very little sun to set it even in the summers. Someone said use the UV light cure unit I have, But since the turn table is not made for heavy water filled containers I can't use that sadly. And no toxic recycling firms I seen around here. No car so transporting it be illegal on public transport. So I have to give up on resin printing if I can't sort out a way to even set the water filled resin I already stored neither known any new amount? the new Elegoo Neptune 4 Plus is on route I've been told so it be good to have. 😉
Hi again, I thought I update you and others on my printers. I now got the new Elegoo Neptune 4 Plus Printer and just set it up on the worktop where the Delta and Aquila were. I removed those two and thought I see if I could get the the Delta working right if not I would carry on the dismantling of it along with the Aquila? I found new Firmware for the delta and tried it, it worked. Now I only need to dismantle the Aquila as it is not working right? So after putting the Neptune 4 Plus up with the other printers, I have enough worktop space to put the delta back next to it and use that after all. I plan to make a small room in the space room they all are in! They sit in a alcove area on two tops so I will just put up two walls of wood and put in sound proof tiles in there so the sounds of the fans etc. don't upset me next to there in my bedroom? The anti-sound tiles also are fire proof too so two things sorted in one go. Hope your all doing well. cheers. 😉
Glad everything worked out! Sounds like you should be video recording this whole process and make a video out of it! People love to see how they setup their workshops!
Fun video. Have you noticed an increase in your z-axis with this mod? I have ordered and received all the linear rail kits and I was wondering if it would be worth it to buy the belt kit. Thank again for the video!
I’ve noticed it operates a lot smoother with the belts compared to the rods. I haven’t pushed the printer to hard are just yet. Working on another project at the moment.
you are the first review ive seen who actually bought the printer for themselves and as such didnt get a review sample which is guaranteed to be better QCed.
It’s the first round of a new machine. It’s gonna have issues. I just wanted to point them out, so new buyers are aware of the situation. I love the printer just had to disassemble it after I just assembled it 😅
What a crybaby
Thanks 🤓

Aye what a time to be alive 😂
Plus I’m 30, my internet use to make a lot of noise just connecting 🤣
Why did you make this when the official TBSTron3D videos are so well produced? 😂😂😂 Seriously though, great job. Great procedural organization, communication, camera work, lighting, and editing. Just one bit of input: Many people, including myself, are going to be installing the Z belts and Z linear rails at the same time. Your well written procedures go out the window when we have to combine two videos…so please consider making one last video in the series for the whole Z job. You may even be able to get away with using only existing footage and some editing magic.
At the time of filming the other videos Z belts were not available. TBStrons3D sent them out as soon as they could, they obviously can make the video fast then I can. But I will keep that thought in mind when doing other videos! Always appreciate feedback and thanks for watching!
@@EdsTechTalk94 I was being sarcastic about the official videos. They’re the worst thing I’ve put myself through in ages. I recommend you avoid them and just take my word for it.
@@TheOfficialOriginalChadI agree they’re not the best
My assembly experience by comparison was a breeze. Despite the manual suggesting screwing each leg in one at a time, I socketed them all in before screwing. Then it only took the lightest amount of pressure to seat them. The only real issue I had was that my nozzle came clogged from the factory. Luckily the included cleaning tools were exactly what I needed to deal with it.
Glad its not all the printers with the fitment issue. I luckily did not have a clogged nozzle!
Keeps pushing me to app installer contoso then says its a virus
I believe that is normal, and mentioned in the video.
I did mine at 500% and yes they come out better when its bigger hahaha…
Just about every is better big 😂
hold on to the micro sd card you will need it to update the firmware in the control pad when new updates come out.
This is very true if it is your only one, but most people have a stock pile of these. And if not they a very cheap nowadays.
