Great work Aurora and team.

Excellent video finally someone did a full set of tests 👍

This is the review I have been searching for! Very helpful. I really enjoy the b-roll shots that show what you’re talking about when going I’ve the features. I ordered this printer thismorning (before your review was uploaded), and I’m happy to know I made a good decision on a printer to replace my older troublesome creality cr-10 max.

you make the best printer reviews

This is the most in depth review I have ever seen on any 3D printer yet! Thank you for this, I will definitely be taking a look at your other videos as this will help make my decision on my first 3D printer. Wonderful!

Wow 🤩 I love the assembly instruction visuals! Definitely keep that, well done 👍.

Excellent video. Thank you for the thorough review and comparison. Really helped me make up my mind

I love your voice as well! You are a good presenter. The review is on point with excellent technical evaluation, detailed and clear descriptions, and helpfull comparisons. Subbed!

Great video review as usual. Very detailed and thorough and unbiased.

Amazing review Aurora! I was looking at either the Neptune or Kobra for the large print format. Now that I have seen both reviews from you I know which one I'll be ordering.

I love your voice. Even if I cared nothing about 3d printers, I could still listen to you all day long.

Jeeez! What a detailed review. Nice! Helped me with decision. Thank You.

Thanks for your great reviews as always... This one saved me from not making a mistake, being forced to used the "cloud" for network printing is a No Sale.....Thanks!

Amazing! Thank you for the review!!

Very detailed. Great video, thank you

Absolutely! Here's your comment: *Wow, what an excellent and well-thought-out review! I really appreciate you taking the time to thoroughly cover the AnyCubic Kobra 2 MAX. I'm seriously considering getting this printer or perhaps the Neptune 4 MAX. I guess I'll wait and see which one I can snag for a better deal. Thanks again for the great content!*

Expecting this printer in a couple of days. I didn't have the others to test against, but the reviews convinced me. Also, swore I wouldn't buy another printer with leveling wheels.

Glad do hear it performs well... because I couldn't wait and already bought one 😂 👍

I must say your channel is very informative by the way you do your testing.

Great Video! Im a newer 3d Printer/maker and content creator and that was very informative and precise

Great! Perfect review!

Great video, thank you for sharing.

I got the Kobra 2 Pro a few days ago thanks to your recommendation list. It's working very well, I'm glad I listened to you, thank you all for your hard work :)

Hi Aurora, great video as usual. I just wanted to give a hint: i believe that the reason why there is not any calibration in klipper for resonance at tall heights is because what you are experiencing at the top of tall prints is not printer resonance but vibration of the printed part itself, so it will depend also on what you are printing, and cannot be calibrated in advance. You usually test the tall vase which is very light and tends to "move" more. If you can i d make a test with a more "solid" print to see if the effect is less noticeable. Hope this helps Cheers

Sounds like a solvable problem for Klipper, but absolutely way more complicated than the basic input shaping case. A basic approach might be for Klipper to pause large prints after each 100mm in Z height or so, and doing temporary input shaping recalibrations.

Very neat printer but I love cheap secondhand printers I know I love working on them and fixing them ❤

Outstanding video as always! Just wondering, are you planning on reviewing the Ender 3 V3 KE? If so, would you recommend that over the Bambu Lab A1 Mini? Thanks as always!

Great review as usual. Just subbed. I'll put off buying the Kobra 2 MAX until something comes along that will also let me print at least ASA and provides hardened steel nozzles as an option. This will probably be Bambu, albeit at a much higher price. 3DJake has this machine on offer for only € 363 at the moment.

Excellent video as always. Please smile more, I miss that cheerful young lady from Danville California. 😊

Great video as always. I'm considering the Anycubic Kobra 2 MAX for a print farm (I already bought one), BUT, the wi-fi printing only being available over the cloud will likely (and unfortunately) send me back to their competitors. Also, they might get a return. We will see. @ANYCUBIC3D

Hi Aurora and Helios, I have one (or more) question(s) for you. Considering you have reviewed and accumulated so many printers, I am wondering if you have been able to test them over a longer period of time to determine which ones continue to work well versus ones that degrade or even cease functioning? In my own experience, most printers that have poor quality components tend to fail within a 30-day period of just occasional use. I am not suggesting that you run up your electric bill with unnecessary printing but even running a stress test of a very long print lasting several days might provide some insight on component wear, misalignment propensity, or build quality degradation. And if this happens, I wonder how good their support of their products would be via phone, text chat or email. So, if you ever wanted to add value to your exceptionally great content, this might provide you with a way to revisit printers you have reviewed to see if they are still worth the cost of ownership after extended use. Thanks!

Great info thanks!

thanks for the review. I just purchased this printer from MicroCenter for $399. Hope I made a good decision.

Thanks for the video! I’ve been looking at the Elegoo Neptune 4 Max, but the Kobra seems like a better deal overall.

I think the same

Great video Aurora. I’ve been using this printer daily for almost a month now and it is okay, but is much to closed off for its current abilities. This printer is quite decent when printing in PLA but it’s annoying that everything is geared toward printing in PLA on it; all calibrations and are hard coded so can’t optimize the calibration for PETG which needs to be printed at higher temps; also more calibration points for a print bed this large would be much better; would be nice if their firmware allowed the ability to specify the inputs on their calibrations; some feedback for anycubic if you have a contact with them

Great job, as always👏🏻 will you test the Creality cr-m4? Thank you so much for what you do👏🏻

I have three of them now. The problem I have is with large prints taking up to 10 KG of filament. The lower layers can print fast but above 1KG +- .5 kg you need to slow it down, because it will JUMP and print off sometimes up to 6 mm, but mostly about 1.5 mm. It could be the Y motor need to be aligned to the exact magnetic position of that motor. If you are halfway in between the motor 1.8 deg motion, you are in limbo and it will slip to align with it. I have not figured out how to set that. I have now 4 completely worthless prints. I will keep on trying different settings. But maybe it is the dimension of the part does not lend itself to a precise 1.8 deg motor setting. But this Kobra 2 Max is amazing on under 1 KG. I keep trying to print at 230 MM/ sec and huge prints, do not work. So, have to slow it down after the first 1KG roll.

I hope AnyKubic opens up their hardware…it would transform these Kobra series printers. Assuming they don’t use a noisy motor like mine has. I also think their leveling may be a little flawed. I’ve had to live adjust my Z on occasion.

And its on sale now for $519! I just grabbed one ;) Oh, and free shipping!

I was going to buy a kobra max 2, but i have a kobra max that I can't find parts for, so I fear the same will hold true for the kobra max 2. PS. I really like your channel, I haven't watched it more than a hand full of times, but i do like your reviews, and I Think you have the best channel out there.

Great review! One minor nit, I think: the little cleaning block is made of silicone, not silicon, I presume. Pure silicon is a hard mineral. Silicone is family of oils and rubbery polymers.

I hope my anycubic kobra 2 max coming tomorrow 😃

Awesome review, I seen this printer being used from another YTber and I am interested. The price point isn't bad. I like the size that it allows, going to use this for printing RC 1:10 scale parts and bodies. I was wondering about spare parts and the filament tube about it's longevity. Als meant to ask, how many times did you have to clean or prep the bed

thank you, you prevented me from wasting my money! since it is not even possible to drive it via USB from Octoprint, i can not run it, since internet is not always reliable here.

Your website is awesome and this review is so freaking thorough. So useful! Assuming one was in the market for a large 3D printer along these lines, do you think it is worth waiting to see if something else hits the market that can beat this machine? What are your predictions?

Great video. Using the Kobra 2 Max for a month, the auto leveling works pretty bad on the edge of the print bed, especially on the left, which is the same as your result. They get too close on the left and too far on the bottom right. Any suggestion to improve the bed leveling? With no adjust knob, this is just something I cannot fix. Also, the nozzle seems wear out fast for the one comes with the printer, strongly recommend to change to hardensteel nozzle.

Check your gantry distance from the bottom to the bed (I used the Rook for Kobra 2 max on printables) can use anything that allows you to check the distance tho; mine was off about 2mm from right to left, the rook gave me a stable surface to be able to level from

I've heard of soneone putting sticky notes under the bed to shim.

Carefull with the auto Z-Offset. Mine was set 2mm to low, scratching the bed before I caught it, du to plastic being on the nozzel. The offset sensing works over conductiveness and the wiping doesn't work propperly, so filament residue can mak the leveling fail without any indication, ramming the nozzel into the bed.

I have the Kobra max. I modded the cooling duct and converted it to a direct drive. I have zero problems as I'm using this for mass production vs volume. I was really hoping they'd go with a true direct drive however I may get this anyway. Thank you.

bytlan here, have you ever done the endurance testing of these 3d FDM printers. I have a list of machines I have bought over the years and they all have failed. (um, the motors all still working fine individually, but left in the board, they just crap out) Some I've replaced the mobo's (up to 3) times and never got a print or would flash correctly. others I've run and got only small prints to work when they were to 300mm mark sizes. Davinci enclosed ($500) was my first machine - ABS great... Anet was next, the build was crap till I did the rebuild on those plastic frames (8bit) and got like 1-1/2+ years before a mobo went and replaced. And the list of machines bought just all failed after only a couple of months to a 2 year run on 1 and they don't make anymore. I have 2 machines currently still running prints OK. None of them are Klipper. Not that I haven't tried to convert just not figured out the install to work. I am rather convinced they are all designed to fail - chips preprogramed to do that (designed obsolescence is a known engineering process). I am at either hot mail or yahoo if your interested in my results. I've written the many companies and the results are equally so disappointing. Also a few China KZreadrs who were posting on much of the same products of your site and channel shows she did and would do more with open source is no longer posting. I've found out the GOV have blocked them from future posting. Also many companies get emails blocked as they claim nothing received, yet nothing of failed email delivery replies or returned to me information. The knowing of good machine performance is good information as you post quite well but the endurance and even service reply is still quite a lot of left to be desired. You as a promoter may not get these results. warranty often does not exist for anything purchased from China, it does not exist. Thank you! Please keep posting as I do enjoy them - even your flubs are good to see you as a real person. Not much known of your brother though... just keep it up and your posted www site. Thankx...

Welcome to the club. During the time you would have been waiting, you were actually printing and having fun, hopefully. The worst plan is to buy a printer (because it's on sale for example), and then not use it for like a year, because by that time there will be better printers out for less money. And the last year of so of new printers has proved that in spades. I don't know that we'll see innovation as rapid in the coming year, though. We may have reached another plateau for awhile. Bambu Lab really set the new standard.

Great video! I like that you print so much tests and it claimed outstandingly!!! I am maybe considering buying a Anycubic Kobra 2 Max, but this closed wifi is a compromise… I also think it is difficult to calibrate Input shaping at higher print heights, but maybe via algorithms they can compensate it better. One Tipp I would give, before autoleveing, let the heatbed heat up for somelike 15min so it can deform how it would while printing, as if you do so the levelling is much more accurate. I have heard other creators talking about this. How long btw. does it take to heat up the bed and nozzle? Sorry for my language

@AuroraTech

5 ай бұрын

Heating up the nozzle is fast; it takes around 1.5 minutes to go from room temperature to 220°C. However, all DC powered large beds heat up slow. It takes 7-8 minutes to go from room temperature to 60°C and 18-20 minutes to reach the maximum temperature of 90°C.

Hello, I just bought this printer and I m glad I found this amazing video! I was looking for nozzles in amazon and apart from what you showed, I found others that didnt have the ''butt'' in the end(volcano style). However, some people said that it worked for their kobra 2 printers. You think there is no chance a volcano nozzle fits this printer without any hotend modifications? thanks

Thanks for the review decided to buy one. Ive heard from some people normal nozzles still work is this something you wpuld be willing to test?

I think you should be using the exact same filament among all printers for most accurate results as filaments really vary in quality/ flow/ temps etc.

Ай бұрын

If those were the only 2 options, I will get the Kobra 2 Max. The FLSUN V400 is a good machine, but it's too tall for that print volume (300x300x410). Its actual print volume is 150x150x3.14x410 = 28,966,500mm³, which is 24% smaller than a 300x300x400=36,000,000mm³ CR-10 style bed slinger as the V400 is a cylinder. I would rather keep a large machine like this Kobra 2 Max 420x420x500=88,200,000mm³ with a 3.04 times larger print volume with a lower price.

I’m having issues with layer shifts and they range from minor to extreme I’ve tried everything from loosening to tightening belts to tightening the screws and the pulleys everything

Hi if you want to print ABS can you upgrade the heat bed

Hello! I wanna ask what’s the z offset you use? Mine keep fell down for some reason, the support tree and first layer not sticky enough. I use default z offset 0.01mm

Amazing size, seems like a good printer for the price, but I noticed it's loud. It's annoying that lots of 3d printer manufacturers don't focus on the fan noise

Did ya oil the linear rods and u wheels? They can wear. Does it print via internet without using their slicer interface/ app? Not my tea there really. Might be cool ig if free. Overall, hardware looks great otherwise. The 'llama' print had some odd z lines, compared to the others but time was zippy fast.

I just finished returning this printer. I started a large scale print and the printer died one tenth of the way into it was not able to power it back on. Very disspointed. Upgraded to a Qidi X Max3

Wonder what items can be printed in such a big size (420x420x500mm) when ABS/Nylon/Polycarbonate can't be used.

How about the best printer for abs

From 500mm/s you changed to 250mm/s print speed for PLA, so its not really a fast printer, even when you change it to 50mm/s, its still shows stringing, ghosting and ringing @17:05, the new firmware updates reduced the recommended speed to 150mm/s. Direct connect to WIFI is still not working. The nozzle and block is unique design and you cant find it on the market, if you order from them with a bigger nozzle size! they say only print with 0.4 size and they say we don't recommend to change to bigger nozzle size and it is not open source printer.

Darn...lost me with the lower extruder temperature and proprietary firmware... I was leaning toward this over the Neptune 4 Max but I really need a higher temp hot end and it doesn't sound easy to upgrade...

I'm confused by your rating system. I'm looking for the best large 3d printer but this is the only large sized 3D printer on your website or did I miss something? I would like to point out I am blind and my reader was having trouble with your website.

Hi, I have enjoyed watching many of your videos and respect your advice. I have to say I bought a Kobra 2 Max and had several problems with it ranging for failing on every ABS print I tried, to just randomly stopping during 3 prints, to having the unit dig a hole into the build plate twice, to having several problems with the Z axis settings. I was unable to get any useful help from their customer service dept. Other than automated messages saying that an engineer would contact me, I really got almost no responses to support tickets or emails. Now, I have sent several emails and a support request over the last few days asking for an RMA and shipping address to return the product and I get nothing. This is not a reliable product or company from what I have experienced. I know this is a huge printer for the price, but if it does not work, it is a huge, pretty expensive doorstop.

I am sure you get outstanding responses from their customer service department, but the rest of us are treated like a disease they are trying to stay away from. I can’t believe that they are so busy they do not have time to answer an email with a request to return the product, or even that they are having problems. I know this printer is very large for the price, but, if you cannot make it work and you cannot return it, it is just a BIG rip-off !!!

They use input shaping on new printers so the vibrations are compensated for through software. However having used a printer that doesn't have input shaping it's not that bad, it just adds a kinda subtle change in colours usually like a sub texture in each layer.
