I leveled it 1-3 and 4-6 a few times hit the auto level tolerances were okay, printed the buddah then leved it 1-3 and 4-6 while the bed was hot got the level even better and haven't had any crazy issues yet. This video is great thanks for the helpful tips.

[@RDUBTutorial]

Great video- I have a 3 MAX and almost no issues. The SUNLU pla+ I got off Amazon is great and settings between black and silk copper are basically the same. I put my pla in humidity controlled boxes - which could also effect people’s prints. Week one - fresh pla then week 2 the pla could be full of humidity and dust…so one other thing to watch for. Great tip on the belt dial locks and cable chain. There’s a z axis cleaning tool to get crud out of the big up n down screws. Still trying to find the slicer settings for the supplied Buddha print cus those print perfect every time. Gonna watch more of your videos now.

This is a great video and has helped me with my Neptune 4 Max

[@PeterTeuns]

This is so spot on! I think, one of the major problems is, that manufacturers suggest to their customers that 3D printing is as easy as 'normal' printing, but there is so much more to it. 3D printing is high maintenance. Next to the daily and weekly routines come tasks like replacing the nozzle or the ptfe-tube where you can easily destroy parts of your printer if you are not careful enough (i.e. breaking the ceramic heater when grabbing the hot end in order to unscrew the nozzle... been there, done that, no T-Shirt...). And yes, there are tutorials from Elegoo for those tasks here on YT, but yeah, if you got two left hands, all thumbs you end up breaking things. But that's not a marketing message to increase sales ;-)

[@OuterRimArmorer]

Thanks for the confirmation that’s it’s not just me having bad luck. I swear I’m always fixing one of my printers. I’ve owned 4 different brands of printers and they all break eventually.

[@chrisalister2297]

Thanks for sharing your experience with it.

[@OuterRimArmorer]

My pleasure!

[@primoxsilverfox2378]

I have the 4 plus but that tip on turning off combing really helped. I also had a few prints get kicked off the bed before making the adjustment.

[@OuterRimArmorer]

Glad it helped! I had to beef up supports as well.

[@blazet9860]

Is combing in the slicer settings or the actual printer? Mine is now getting a dragging type sound , but that's not it. Any suggestions?

[@OuterRimArmorer]

@@blazet9860I believe combing is in Cura if you’re using Cura then it’s under Travel settings. Enabling Z Hop should also help. It’s in the same section in Cura. If you’re using another slicer software I can look up where Z Hop is and let you know.

[@blazet9860]

​@Extreme4x4Dude I'm using the elegoo cura. The sound I'm now getting sounds like a lube issue along the z axis. What can I safely use there?

I’m printing around 250mms and .2 layer height.

[@CCGamesceo]

Good video. I took my large fan off too. It causes clogs. If a print started to fail it would hold everything right by the nozel. I felt like it was safer to run without out it and just go a tiny bit slower.

[@Reckless3057]

A guide for what to tighten would be amazing.

[@OuterRimArmorer]

I’ll try and put something together.

[@unger_cnc]

Sounds like some blue loctite would help all parts from loosening up so you don't have to tighten them every week. Figured once the belts and v-wheels are broken in, it should be set it and forget it for awhile. Thanks for pointing all this out. Still on the fence about getting one. Hard to beat it for the price even with all the little issues.

[@psychoomega]

wow, great advice..... after almost 2 months of owning neptune 4 pro I just realized the wheels and some screws weren't tight enough.

[@OuterRimArmorer]

Glad it helped!

[@MrVelkroTek]

I got the N4+. Is my first journey into printing and so far has been pretty good. I have had a couple of failed prints but due to user error and we all have to learn sometime. I am still running stock firmware I think like .28 and have not upgraded the firmware yet as things just seem to be working nice. I do have an issue when I turn the printer off and later back on and also when I change filament, I have got into the habbit rightly or wrongly of doing a small first layer test prob 10cm diameter and find that the first one i do every time looks like the z is too low and for a while i would go up and down until I found it good again but it sometimes took a good few tries. Now I run a small first layer and rather than making adjustment I wait till it's complete and then run it again straigt away or just start a print and get a great first layer every time. Sorry for all my woes. Anyway thanks for the informative notes to take heed of. I am curious as to whether there is a specific type or brand of white grease you recomend and also I have noticed the pom wheels on the gantry wearing a bit and wondered when they need replaced and whether the generic vpoms like the unes used on creality printers would be the thing to get or are they manufacturer specific? cheers, look forward to more ;)

[@OuterRimArmorer]

Thank you for watching and I hope the information is useful. I have had similar experiences with both the EN4M and the AK2M. Sometimes I start a print and adjust the z height on the fly. Once I get it right I stop the print and restart it right away with the z height. Seems to help. I noticed a firmware update is available for the 4 Max but I’m waiting to see how other people’s updates go first. I’d hate to update and make things worse. I do believe they are a standard size POM wheel. I have some extra ones so maybe I should check. 🤔

[@smccrory]

I learned from motorcycles and RC helicopters that blue locktite is pretty much required for all metal-to-metal bolts if you don't want them shaking free.

[@C-M-E]

While I expect that printers of a certain price range seem to fall into the "hobby spec for upgrades" end, having that happen either out of the box or within a week of ownership means the thing was adapted from a smaller platform with the same parts and is wearing itself out Real quick. I have a fairly steep maintenance regime with a 6 year old delta that's two meters tall, at this point it burns through hot ends about once a year and is due for a bottom-up rebuild this year. If I were getting _that_ experience from new, I think I'd be swinging an axe or flaming pitchfork too!

[@kbranchjr]

Thank you for your insight

[@BeeKing]

I’ve got the plus and max. Straight outta the box my eccentric nuts on the bed was all out of what. Middle ones was severely over tightened. Took days but my max is printing now. I about threw the wrench in lol.

[@OuterRimArmorer]

That sounds like my experience with 3D printing. When you feel like smashing it, walk away and try again later. I swapped out the Pom wheels for linear rails and ditched the eccentric nuts. Life is so much nicer now. I was getting about 6 weeks out of my Pom wheels before having to replace them. Someone said it was probably because I had them to tight but I’ve been doing this along time and I really don’t think that’s why. These new machines print so damn fast that they just wear out quickly.

[@mechnut450]

Mine will be delivered in a few days.. i was thinking about the silicone 😊bushings. I am also considering to get the oldham couplers for the z screws. I saw a huge improvement on my Ender 3v2 when i swapped them out.

[@kiiiddd]

Go into klipper and find your pause macro in your cfg files. Then you will find the line that moves the print head to a safe location during the pause. My guess is the X value for the pause is at X0 and that's why it's hitting the gantry, change it to like X5 or something so it won't bottom out

[@michaelpolofka2293]

Maybe slow the movement for the pause down too. If it is slamming into endstop.....

[@OuterRimArmorer]

So I’m looking into this because both of my printers seem to layer shift after filament changes. One printer shows M601 and the other Shows M0. Both basically mean pause but neither of them show anything else as far as gcode is concerned in the Pause Print G-Code section.

[@piercepcp]

this could have saved me some time had I found it a month ago... You are 100% correct! great printer but requires regular upkeep! I have no problem with that but I suffered from the Z leveling issues which caused a thermal runaway, get new printhead it clogged almost immediately after not sensing or saving the Z height, which also gouged two beds ( I used my n3pro's as well). So in fixing that tried to replace the nozzle and it snapped off the neck in the heating block. .then the first update came out. Thought it was fixed, nope. Printhead grabbed the top of a very well adhered PETG CF print..... holy hell. snapped the bottom of the frame right off the printhead! but with my trusty three I managed to print a hero me upgrade and wired up the stock fan to get it working again only to struggle for a few weeks of checking this or that to go through most of what you did until I realized it wasn't just a hardware issue. that was about three days before the update; which has resolved most of my issues. I guess I'm saying I understand why people gave up but with how good my three was I knew it could be great and it is, now anyway.I still love it you Won't get a better bang for your buck! oh and F the nozzles ! do yourself a favor and just order volcano nozzles and adjust your Z height for the difference. upgraded to 5015 blower fans printing at 200mm/s.... now waiting on .08 and 1.0mm nozzles! I must be in a cult, I still love it

[@piercepcp]

And I'm off to order silicon spacers and print the cable chain that I've been putting off. keep up the good work!

[@OuterRimArmorer]

Holly hell that sucks. I’m like you though and I eventually work through the issue. Overcoming it all feels like a great accomplishment but the process is still very frustrating. Glad yours is working better now. I’m interested in that volcano swap. Need to learn more about that. I did just receive my order for .6 and .8 nozzles so I’m going to give those a try soon.

I added the M600 macro and tried a color swap that would work all day on my Cr10 but got the same layer shift you mentioned. I'm going to try the M600 with and without the filament runout sensor enabled and see if it makes a difference.

[@addmix]

Did you ever come to any conclusions with this? Are you able to do a klipper macro to disable and reenable the runout sensor?

[@crushingbass7131]

I have the same printer, and I absolutely love it. It's my first printer, and I find that it works really well. Every time I have an issue, I am able to solve it pretty easily with general maintenance. I dont really understand why the reviews are so bad. The one thing i did that improved my prints massively was to switch to Orca slicer. Im honestly not sure what it is, but my prints look better, and my machine runs a lot smoother as well.

[@OuterRimArmorer]

Thanks for sharing! I love mine too. I actually bought a second one I loved it so much. The linear raid and silicone bushings are a huge help as well. A bit of blue Loctite on the knobs helps them from giggling loose all the time. I went a step further and replaced the bed knobs with locking nuts. It’s a bitch to manually level the first time but I haven’t had to manually level the bed since and it’s been months.

[@addmix]

@@OuterRimArmorer I figure regular levelling wheels that incorporate nyloc nuts would be the best option, but noone has produced them.

[@addmix]

I have found the exact same thing. I've been printing for years, and Cura has always been awful (at least with the stock configs)

[@trevormallow2788]

I can help you with the layer shift issue. In your printer.cfg for klipper find the macro that activates when the filament runout sensor triggers. Comment out the line that tells it to home during filament change. A proper filament change macro should tell the printer to move to the front center of the print volume thenm return without homing. Sesnorless homing is great but this is the primary shortcoming of it.

[@scottsherman3716]

I am still setting up my new Neptune 4 Max printer but I also have been watching various videos such as yours. When I ordered the printer I also ordered Multi-Sizes Nozzles for Neptune 4PLUS/4MAX.

[@Gryfang451]

I got the N4 Pro. While assembling I used blue locktite. I use this every time I assemble a printer. The problem I ran into was not cleaning and greasing the linear rods on X and Y axis. I used Superlube silicone PTFE grease and it works great. Need to get a bed kit for mine. Leveling isn't hard, but I seen to do it way more often on the Neptune than my other printer. More speed, more vibration, goes out of adjustment quicker...

I added screw tilt adjust. added center as base, because i cant align that. 6 corners are compared to center. i adjust all the screws so its max 00:01. i go autolevel. i get 0.4 tolerance. no idea how, z heights simply change from the screw adjust test to the mesh test. its okay, we have autolevel. i get my mesh, but it doesnt seem to apply it. if edges are ok (z height ok), middle is almost touching the nozzle. if z height is adjusted on the middle, filament wont touch the edges.

Wow, a lot goes into this one. I will be honest, I am horrible at maintenance. My last printer I ran it for over a year straight and did not do any of this. I releveled it a few times, maybe once every few months, and aside from the nozzle that was all I did. If it wasn't for the machine getting water damage and messing up the main board (I think) I would still use the N2S.

[@OuterRimArmorer]

This is the first time I’ve had to do this much maintenance on a 3D printer buts it’s also my first 3D printer that can print at 250mms and looks amazing. Plus it’s a massive bed slinger. I’m testing the Anycubic Kobra 2 Max right now and working on a comparison video. So far it’s less maintenance but I did just experience a glitch in the firmware or something that ruined my print. The review was looking good for Anycubic until this happened. Lol

[@StylishJedi]

I eventually had my 4 Pro shake so hard that all the beds level dials fall off and it blobbed the entire printhead. Before that happened I had just re-leveled it washed the build plate and even put down some glue stick. As per usual I watch the first few layers go down at 40% speed and then increased it a little bit for the rest and went to bed and woke up to the entire printed being engulfed in a blob, of course this is not unusual. Usually people just turn on and heat up the system and melt the blob but my system wouldn't even turn on because it couldn't sense the nozzle. This was within 14 days so I asked to return it. Getting a Bambu A1 mini instead. Will get a bigger bed slinger too but haven't decided which one yet. Just a bit worried about these ELEGOO's. I had many pretty successful prints and some really bad. I learned a lot from looking up all the different reasons, but gave up when I was blobbed. Of course offered to send me a new printhead. But I also decided that I needed a bigger, build volume like the max or the plus at least.

[@jonathanboileau9025]

Did you put silicone spacers in the center or just leave the metal ones? Also did you have to trim the insulation to get the spacers in there? The holes in the insulation look smaller than the spacer and would possibly crush the insulation.

[@OuterRimArmorer]

I did replace the two center spacers with the silicone bushings. I did not trim anything.

[@imst4722]

Cable chains are meant to be supported on both ends with a limit on bend radius. They're also meant to be used with specific cable types and without any sort of sleeve. It's more likely that you're shortening the life of those bed wires rather than extending them as intended. If you really want cable chain then swap the wires for ptfe insulated wires or even actual cable chain wires, print mount points for chains on the bed and frame (so there isn't added stress on the cables), and buy/print some proper cable chains. You can check out the voron zip chains or the micron printed cable chains.

[@user-lx9jm1wo3h]

Your Y axis wire chain is not really working the way it is supposed to. Because its basically floating in the air, its only bending your wires in one spot which will damage the wires much faster. You should also put a little oil on your roller wheels to prevent them from chafing and turning white like they look in the video. I use superlube with ptfe and i put a tiny drop on my finger and then just roll the wheel while i smear it on. You just want them to look a little glossy so they glide along easier in the v slot.

[@ryantoth531]

Even if you pause the print, it will do a layer shift!

[@OuterRimArmorer]

Stuff does come loose on most printers especially if they are fast ones. Adjusting eccentric nuts, tightening belts, and leveling bed is probably the most common. Some printers require slightly less maintenance. I have not had the privilege to get one that doesn’t but I hear they exist.

[@DiavloPL]

today screw that held filament sensor unscrewed during the print :D

[@josephmunson3945]

I am having the z offset issue super bad, did you tighten up the bolts that hold the little brass pieces that the Z rods run through? Originally tightened mine up because they come loose.. When I started having issues I loosened them up back how they came and my problems are worse than ever. I can have a layer perfectly level and uniform looking then half way through its seems like the Z offset is way too low. Sometimes I go to print and the z offset is way to high sometimes its way too low. could these problems be associated with the bed being unlevel because those knobs under bed are coming loose?

[@OuterRimArmorer]

Those little brass pieces on the z rods are meant to be loose. Make sure your z rods are greased. The bed screws loosen up all the time on me. I just printed some bed screw locks to give them a try. My concern from what you mentioned would be the z gantry changing. You definitely want that thing to stay level.

[@josephmunson3945]

@@OuterRimArmorer okay 👍… so maybe worth a firmware update to see if that fixes my random z offset problem… otherwise keep those brass things loose and everything else pretty tight and mechanically I should be okay?, my issue probably lies in the software or something.

I change filament while it’s running so I don’t get layer shift I did find like ur self that rollers loosen often

@@OuterRimArmorerI have Neptune 3 pro Neptune 4 and 4 max I do it almost every day I think there is a video on KZbin showing how to do it good luck happy printing

[@craigdvance]

One thing I just noticed on my 4max is that the bed is getting wobble, I need to figure out how to tighten that down

[@OuterRimArmorer]

Your POM wheels may just need some adjusting. If you find that no matter which way you turn the eccentric nuts/spacers the wobble doesn’t go away, then you may have worn down POM wheels. Mine were grooved pretty bad when I replaced mine. Also it doesn’t matter which what you turn the eccentric nut. It’s really just a lopsided spacer that’s thicker on one side. It will either tighten or loosen. If it never tightens then it could be time for new wheels or linear rails.

[@user-mw3ht5kp2p]

that printers runs on klipper right. The way it movies out for a filament change can be redon in the software. And you could even add a machine base measurement so it does not even touch the side. Klipper is awesome for that. And you can easy add or remove scripts.

I would say that there are easier printers to learn on.

I think only slightly better. I still have to relevel the bed weekly it seems.

Is this error on your printer or your computer? Slicer software has a tendency to take a lot of CPU.

I haven’t used PrusaSlicer for the Elegoo’s. I could try and setup something though.

I had similar issues at first. Mine turned out to be weak supports that kept breaking. The bed adhesion was good but my supports needed to be beefed up.

I actually just posted another video showing how I setup my Cura Neptune 4 profile and the settings I changed. I might post another more in-depth video on my settings once I feel like I’ve really dialed them in but what works for me might not work for everyone else mainly because the filament you use greatly affects the settings you need. I cover a lot of that in the video as well. Hope it helps.

Have you had the z offset issue people are reporting? Dang z offset changes every print, every bootup. The times I have managed to dial the z offset during the first layer it's a solid machine.

I have bought this printer last month, but from a week or something more I my prints have some layer separation, on the other printers that i have I haven't experienced this problem yet, is it a common problem? how can i fix that?

[@OuterRimArmorer]

I’m experiencing this very same thing right now on my Neptune 4 Max. I switched to a different roll of filament and it sort of helped but now I’m testing PrusaSlicer instead of Cura to see if maybe it’s my slicing software or settings. Orca has a profile for the Neptune 4 Max and that software is similar to Prusa so maybe I’ll try that as well. 🤔

[@OuterRimArmorer]

A friend just told me that normally separation only happens if your print is not hot enough or cools down too fast. I print in my garage and I’ve been printing around 200 so I might bump it up to 215 or 220 and see how my prints look.

[@Visionbygt]

@@OuterRimArmorerthank you so much for the answer! I’m trying right now, I have also imported a file from an Anycubic, maybe is this also part of the problem🙏🏻

[@OuterRimArmorer]

@@Visionbygtif the file is an STL you sliced using Neptune profile it should be fine. If it’s a file sliced for an Anycubic it could cause errors only because different machines tend to have slightly different gcode. That being said I have done it myself with little to no problems. It’s just safer to stick to the gcode designed for your printer.

[@Visionbygt]

@@OuterRimArmorer yea for sure safer, I’m running a small 3d printing farm for a racing team and I have 4 anycubic and now the Neptune 4… I wished that I could use the same gcode to save some time…
