Anycubic Kobra 2 Max 3D Printer, Max 500mm/s High-Speed Printing Large 88L Printing Volume with Auto Leveling Smart Z-Offset Vibration Compensation Enhanced Print Quality & Detail 420x420x500mm

Huge printer, super fast, has some small minor quirks but easily worked around, for anyone wanting a flat build surface and can’t find a larger PEI sheet; I flipped the bed around and put large style Kapton tape to the other side the same way you put on window tint and it still levels perfectly because of the metal which is how the leveling system works! Holding up nice!

I have had 3 years experience 3d printing various table top models and game pieces large and small with an Anycubic Vyper that I have been happy with. Positives: Out of the box the Kobra 2 Max was relatively easy to put together. Wifi simple enough to set up and calibration, auto-leveling, and vibration compensation easy to run. Menus are easy to navigate The size and speed are impressive for the price especially for people who haven't upgraded their machine in a while. Negatives: TL;dr: everything else. When printing with brim, results varied even with no changes made to settings in slicer between prints, and regardless of cleaning/replacing parts, rerunning auto-leveling, etc. Brims would print very messy with strings going every which way, and either way too thin and crispy, or glopped all over the place. The machine would randomly print too high or too low. Many times it would start prints millimeters above the print bed causing nothing to adhere, or start too low dragging and scraping the nozzle along the print bed. This would happen after looking at steppers, adjusting files in slicer, and re running all calibrations and leveling. Prints would have inconsistent z levels leading to gaps in the layers. Machine would knock into supports causing prints to fail. Even test prints would have issues. Printer obviously has a huge footprint and the weight to match. Combine that with its acceleration and speed you have a machine that will shake even the most sturdy of tables like a bully shaking a nerd for their lunch money. Even at less than half speed it is still an issue. Fine tips of prints come out very globby no matter what settings are used. Machine does not handle overhangs well. Could these problems be troubleshooted further and maybe even solved? Yeah, probably with tech support and maybe replacement parts. But you shouldn't be expected to do all of that for a machine straight out of the box. There is no point to size and speed if you cannot trust your machine to handle larger/longer prints. Machine was returned.

I mostly use my printers for TTRPG terrain using PLA filament. At first I was disappointed and a bit overwhelmed once I realized that the bed wasn't level and my prints were failing. Tech support was AMAZING in helping me troubleshoot the situation and pointing me in the right direction as to how to fix my situation. After watching a video provided by tech support, I was able to resolve my issue, and help the auto leveling process along (I know, I know, it should be auto leveled by default, but sometimes this just isn't the case). After all the issues I had when I first started out trying to level an Ender 3, the solution provided was simple, to the point, and I saw immediate results. Another review gave suggested parameters to change to ensure quality prints and they were spot on. If you're running on the "Standard" speed, it's really fast, but the acceleration speed and jerk CAN lead to less than stellar prints. Adjusting these settings in accordance to the snip I took from the review that helped me can be seen above. Once it's dialed in, you won't be disappointed! At the "Stable" speed setting, I was able to finish the dragon skull print in just over 9 hours and the rubble scatter terrain in around 3. Compared to my Anycubic Vyper, I'm shaving off literal days of printing time for each print.

This is currently still the largest 3d printer in its price range. In direct competition with the Elegoo Neptune 4 Max. When I bought this, I had tried to find larger printers in this price range that would be easy to set up, and there still appears to be none other than the Elegoo. I have used this off and on for the past few months, and I can't really say I am disappointed in any way. This printed is probably the easiest printer to use and just get set up within an hour and just simply start printing. But of course, the only reason to by this over any other printer is its size, and I knew I would be printing really large models so I wanted something really, really large, as large as I could get without breaking the bank too much. This really fit the bill since I had not bought a 3d printer before and wanted something easy to set up. But by all means, there actually isn't a reason to buy this printer over any other unless size is a deciding factor. If you need something to print big stuff, this is for you. Otherwise, there is no reason in buying this big thing. There are a couple of pros and cons to this printer. But hardly any actual cons. Pros: -This printer was fast to set up and really intuitive to just simply start printing. -The print quality is good. -Size is large. Cons: -The printer head cable goes BEHIND the printer head, which makes it look like it's going to prevent the printer head from moving all the way to the left side. -The printer head screws were very very annoying to screw in at set up. This is the only part that was annoying and took the longest to set-up. (nobody appears to have mentioned how annoying these things are) -Because of the size of the printer, the print quality is less than other printers out there in this price range. -There appears to be a problem where the print head nozzle will strike the edge of the model occasionally in an annoying way that will make it unstable. I don't think this is because of bed leveling, I believe this is just because of the software it uses on the chip. Enabling the experimental features to avoid crossing perimeters and overhangs in the Anycubic slicer will sort this problem out always. The Anycubic software is really easy and actually is rather well built, even if it is just copies PrusaSlicer. It's slightly buggier currently then PrusaSlicer but they are updating the software constantly and adding fixes/new settings. Some people have complained that because this printer has proprietary software for its chip set, it gets in the way of them using the slicer software they want. I really didn't notice this as a problem too much, since PrusaSlicer works with this, and their own provided slicer software is just a PrusaSlicer knock off. I didn't bother adding this to the cons list only because I didn't truly run into it as a problem with anything I ever needed. You may run into this as a problem later if you are doing strange stuff, but I wouldn't expect this to be a problem since this printer isn't meant to be really upgraded or built out of like some kits are. This printer is set up so that you can just simply print anything big you need to without having to worry about too much. According to some places, the print quality of this should be better than the Elegoo Max, which was the deciding factor in buying this over that printer. There is an "Arc" program on this which supposedly makes a smother finish and connection between layers. As of yet, I have not tried yet ABS or other filaments because they need a better nozzle and enclosure. However, I have never had this nozzle clog once. So, I would also expect there to be no problems with any filaments you use unless you are using some really terrible stuff. I put very cheap filament through this from no-name manufactures with fine results, so I can't imagine what you would be doing to make this clog. Ultimately, I would recommend this printer, even if the only reason to buy it is for its max print size. It's the best value in this range.

High precision and fast prints with excellent output quality. ( I use either a .8 or 1mm nozzle, not a weenie .4, for all my work and the extruder handles it effortlessly. ) The bed surface is a joy, holds the print in place well and releases it easily when cooled. My only criticisms regard minor firmware issues; for instance, if one decides to disable the part cooling fan temporarily during a print, they will discover that it will not turn back on later in the print. Also there is no way to incrementally increase or decrease printing speed slightly , one is stuck with 'Stable', 'Standard', or 'Sport' modes. This means one spends a lot of time dialing things in with the slicer/repeatedly loading the print file for every slight change in speed, a real pain in the butt. As all makers know, with a wide range of filaments and model parameters to work with, getting the exact perfect print speed can be a chore, and an incremental speed adjustment feature would save a lot of time. Another quibble is that Every time I shut the machine off and start it again later, the bed z calibration settings seem to vanish, requiring a bed level run on every startup, which consumes a lot of time. On the plus side, the motion-correction software seems to work quite well; the table I have the printer on shimmy's a bit but this does not affect the print quality. The pictures show my first project on the printer, a 420 hour print of 2 custom designed speaker enclosures in matte black PLA, along with a SPL graph of the finished result. They are double-walled with fine quartz sand between the walls.

When it works, it's great. I appreciate the large format capabilities, and the prints that actually completed turned out pretty good (after the expected tuning). Unfortunately, there have been quite a few problems with this printer. Out of the box, the axis sensors had poor quality connectors. I had to splice a new connector into the Y axis right out of the gate. X axis limit switch worked intermittently as well but seems to have resolved itself. Very very very cheap and poor quality components. I have had this for about 3 weeks and already needed to replace the thermistor in the hot end (tbh it was easier just to buy a whole new head, luckly cheap). But the worst is now the bed doesn't stay at temp as soon as printing starts. It will heat/preheat fine then just shut off. No GCode or slicer issues (previously succesfful prints now fail), and clearly the heater element is working. Ambient temps are about 20*C and no drafts, no fan usage (PETG @255/80). So -- you get what you pay for. Seems like many folks on here have been lucky but I've had more downtime than uptime with multiple independent failures. Being cheap, at least its been cheap to repair but can't say it has been convenient or positive.

It is a product that perfectly meets the specifications stated by the manufacturer. It is easy to assemble and comes with some extra accessories. There are several videos available if you encounter any problems, and the technical support from Anycubic and Amazon is very effective. Plus, it's aesthetically pleasing. It has good print quality, and its calibration was very easy, so if you are a beginner, it won't be difficult. Its interface was very straightforward, and I used Cura for slicing. It had good bed adhesion, its replacement parts are affordable, it has a very large bed, and it reaches a good height. It is a bit noisy when printing quickly and can move everything around it, but it is mesmerizing to watch it print so fast. After a while, I had a technical problem that I tried to resolve. Anycubic was very attentive in helping me, but there was no solution, so they asked me to return it and gave me a refund. But I miss it.

Not worth the money. It seems that anycubic had a bunch of these that had a problem, and sold them through amazon at a discount. Small prints were fine, but large prings suffered from layer shifts, and other failures. I ran two full 1 KG spools of PLA into a print at 50% speed only to have the layers shift 10 layers into spool number 3. I threw away more than I was able to keep printing on this thing. Also other users have had these units catch fire. Wasn't impressed and didn't meet the hype, so it was returned.
