Anycubic Kobra 2 Neo 3D Printer, 250mm/s Speed, LeviQ 2.0 Auto-leveling

Es muy buena en calidad precio y con su auto nivel es muy práctico

Updated review:
Having spent time with this thing, I stand by my prior statements. However, I have since done the Klipper install, switched to Orca Slicer (highly recommended over the alternatives), and fine tuned the printer. With Klipper, Orca and some good settings, this thing can produce remarkable quality at surprising speeds; The top speed is lower than my other printer by half (still waiting to see that 500mm/s), but the acceleration is so high (thanks in part to input compensation in Klipper) this thing regularly out-paces it, and achieves similar if not higher quality on average.

if you have a spare Pi sitting around, and are comfortable with Linux, and don’t mind using Orca, and can find the appropriate guides online, this thing is an easy 4.5 stars for the price I paid. Out of the box, if you can’t/won’t/don’t know how to do those things, you’re gonna have a rougher time getting this thing to produce quality prints at anything beyond your typical Ender 3 speeds.

Positives: Can be upgraded, works great with Klipper, great hardware for the money on sale. More compact than my other printer while having the same print area.

Negatives: Needs to be upgraded to Klipper to achieve anything close to advertised speeds on anything you would actually consider a finished product (or you have to write the Marlin firmware with input compensation already dialed in, I suppose). AnyCubic’s slicer is crap, and the printer seems to behave oddly with objects sliced in Cura and Prusa. Feels cheap and light. Requires maintenance more regularly than my other printer.

Should you buy it?

If you catch it for under $180 and don’t mind a slow printer or are willing to put in the work to make it actually capable, yeah. You’re gonna have a hard time beating the features for the money.

If you’re looking for an easy to use, high-speed printer, just be aware this one is going to take work, and you may want to look higher up in the price bracket for something that will require less tuning and modding to get satisfactory results from. Also if it’s at the full list price, just wait, or pick a different printer. You have better options at that price point.

Original/second review:
Second 3D printer. The first one had to be returned 3 times, and gave me a bunch of trouble. Anycubic has a decent reputation, so I thought I would give the Kobra 2 Neo a shot.

First, the good:
Assembly was simple enough. It printed a benchy and a spider from the SD card quite nicely. It was cheap. When it is behaving, it works well enough.

Now the everything else:
This piece of garbage purges filament on an auto level cycle. Expect to lose around a gram of filament any time you auto level, and it doesn’t even have the courtesy to do it over the board; it just extrudes a gram or so of filament during the “wipe” cycle, then moves to the back of the board.

It is so cheap they didn’t include bumpers on the back of the bed so you can put the build plate back in place easily. I would print them, but that would require the printer actually function.

It has bed adhesion problems to the point where a print failed with a brim, 5C hotter on the bed, and PVA glue to bond it to the bed. Seriously, I don’t know what this board is made out of, but no amount of cleaning, leveling or adhesive has made a difference. Which is weird, because I have seen people print PLA onto unheated glass.

Adjusting the temperature at the beginning of a print has resulted in the printer’s software halting about halfway through the first layer, the printer stops, the head lifts, and then it resets. This is a repeatable issue; all I have to do is start a print and adjust the temperature before the first layer starts printing.

There is no fan control available during printing. You can adjust the z-offset, but not the fan speed. I could work around this with Klipper or possibly Octoprint, but then I wouldn’t be judging the printer on its own merits.

All attempts to print PETG have gone poorly. No amount of adjusting temperatures, nozzle pressure or retraction settings has produced a final product that isn’t stringy, blobby and nasty looking. It’s not the filament, I’m running the exact same roll in my other printer right now and it has printed something on the order of 60 pieces.

The printer looks and feels both light and cheap. You need a rock solid surface or you’re going to be printing very slow to avoid z-wobble and ghosting and layer shifting. The frame isn’t solid enough to keep the thing from vibrating like a child who got into Uncle Joe’s ADHD meds, so you might as well get that 250mm/s print speed out of your head unless you’re going to setup input shaping to cancel out some of that vibration. So far as I can tell, you need to install Klipper firmware to do this, so it won’t be happening.

The webpage is annoying to navigate and appears poorly formatted. I did eventually find the firmware downloads, only to discover that no, there is no firmware update that might fix some of the issues.

Their slicer is pretty basic, so I tried using their Cura profile. About 50% of the time, objects sliced with Cura (using Anycubic’s profile) will cause the print bed to move all the way forward, the print head to move all the way right, and then it will extrude the full amount of filament for the model without moving.

The best part of all this? I bought the printer with filament, so it’s Anycubic’s filament that is failing on their printer. I’m literally cranking out 60 parts to every 2 or 3 that are acceptable quality from the Anycubic. Maybe I got a bad egg, but this experience has made me appreciate how good a time I have had with my other printer, which failed to the point of being returned 3 times, killed a diamondback nozzle and sometimes drives me insane. Other printer is still going, I’m about to box the Anycubic up.

Edit: I noticed a loose v-wheel during dissassembly. I tightened it on initial assembly and the printer ran for all of 3 days before it started having problems. Presumably the vibrations in the frame on the original stand (which was kinda wobbly, admittedly) worked it loose. Added 2 stars to reflect the fact that it is, in fact, functional.

It is still very hands-on getting it to behave, and tall prints still have issues for.. reasons, but if you are willing to put in the work, you can get some decent quality out of this thing. Currently it prints single pieces with similar quality to my other printer doing batch prints. Since it has passed my tests (so far) I will retry my tests with PETG and update results accordingly.. I may do the Klipper install to see if I can use input shaping and pressure advance to get this thing printing at high speeds reliably.

I have also been recommended to try Orca Slicer with it; I will update results accordingly when it’s done.

I’m no professional printer by any means, but in my opinion is a really good printer, got it for a really good deal, amazon deals are really good, i had a old 3d printer that i had, leveling it was a pain almost after 3 to 2 prints having to relevel it was a pain, had to 3d print parts for it, only for it work a bit before problems Occurred again, but this printer, its something else, auto leveling makes it so much easier to set it up for prints small to large, it cleans out its own nozzle and even tip, Small interface but easily understandable, easy adjust while printing, Print really quick with good quality on base settings, i like to slow it down by 25% for better prints which is still pretty quick, and overall a amazing printer, with the way we insert the filament and how the cords function, wont get in way of 3d prints and less hassle with PLA.

I am thrilled with my purchase of the Anycubic Kobra 2 Neo 3D Printer. This upgraded model is a significant improvement over my previous Kobra Neo, which had a print speed of 55mm/s. The Kobra 2 Neo boasts an impressive 250mm/s printing speed, and even when I used it at 150mm/s, it was a game-changer.

The print quality remains excellent despite the increased speed, and the overall performance of this printer is outstanding. It offers the best value for money for a high-speed 3D printer, making it a fantastic investment for both beginners and experienced users.

If you’re looking for a reliable and fast 3D printer that doesn’t compromise on quality, the Anycubic Kobra 2 Neo is the perfect choice. Highly recommended!

Imprime rápido y de buen modo, el único pero que le he visto en el tiempo que le ge usado es que no tiene forma de pausar la impresión mediante instrucción en el código. Fuera de eso me ha gustado mucho
