Anycubic Kobra S1 Combo Multicolor 3D Printer, Core XY Stable Structure | Sealed Printing, High Precision, 600mm/s Fast Speed, Auto Calibration, Ideal for Precision and Efficiency 9.8"x9.8"x9.8"

I am updating my previous 2 star review to 5 stars. The company reached out to me after the first review and “made things right”. They have now released a newer version of their slicer which does support the Kobra S1 with color change. This makes all the difference. The printer works nicely, and now lets me slice and print my own multicolor models. ——inital review —- I wish I had known before purchasing that there is no supported slicer for this printer with four color add-on. The latest version of the anycubic slicer does support the mono-filament version of the Kobra S1, but does not have support for the ACE PRO add on. The work around seems to be some arcane combination of using an older version of slicer, a different model printer, and modifying the machine parameters to match the Kobra S1. This is unacceptable - I think the company should get it's act together before it starts selling the product. I did print one thing on this printer, a multicolor object that comes preloaded as a test file. It's a sixteen hour print. It appeared to be printing without issues, but somewhere around hour 12 on the print a piece of the printer poop apparently bounced out of the discharge chute and way lying on the print bed. At some point the print head pushed against it and caused the Y Axis to lose position. The remainder of the print was skewed in the y axis making the part unuseable. I have to say that I regret purchasing this printer. I will attempt to create a modified Kobra 3 multi color instance modified to become the S1 combo, to see if this will work before I send the printer back. My recommendation is that you skip this model and order something else.

Updated 6/23/2025 - Garbage! Do not buy. Advertised as point and click solution for printing and I have not had it function for more then a few days at a time. Bed is not level and results in prints that are either wavy or ground to pulp on same print depending on where the bed is high and low. It seems that the auto leveling feature doesn't account for individual areas of the plate as the center is typically good and left edges of print bed cannot be used within about 6-8 cm from bed edge so I would not consider this a full print. As mentioned before quality is amazing when working but I have wasted more Anycubic filament than I care to admit trying to get level bed, restarting prints that because of poor build plate layer that went unnoticed until print finished and other issues. Excellent Prints when working. Print head / Hotend broke warped due to rubbing on bed. Unable to use this printer at this time due to unavailability of hot ends. I have reached response from customer service which offered that store offered that more were made available for purchase in store. I will update this review as I receive more information. I ordered official hot ends from official Anycubic site directly. At this time, I have received a message with tracking information that appears to indicate product is originating in China. As of this time I have been unable to determine when replacement will be delivered to me in USA. So far a case of you get what you pay for... I really want to like this printer. I have also purchased Kobra 3 Combo and am enjoying printing with it.

As the title says, this is a very impressive 3D printer that's easy to operate and that produces excellent prints. The filament cassette (the "ACM") is a little finicky to get loaded but after it's setup it works beautifully. The printer is packed very well- props to the Anycubic packing team for a proper packing setup. The printer has too many features to cover, but it's fast, quiet, and well made. The construction is well thought out and the fit and finish are very nice. Some reviewers mention that it's loud but it's not; it's actually quiet enough to sleep next to when it's printing. The screen has enough prompts to guide you in getting a print started, but I wish it displayed more informational prompts telling you what it's doing (e.g. "Retracting filament", "Purging filament", etc. You can see what it's doing but a running 'commentary' would be useful. Sometimes it just sits and thinks for a moment with no indication of what it's doing, but after a bit it resumes and all is well. Still, it'd be nice to see more info messages. All in all though, it just works- all the calibration is automated so you don't have to fiddle with bits and pieces trying to get it set up. We're very happy with it and expect to use it a lot. We've already done about a dozen prints and only had one print that had an issue (a small layer separation area) but the print was still fine. From beginner to pro, I'd recommend this printer without reservation.

The printer looks and feels as a very high end product (the way Samsung and Apple devices look and feel). The packaging was very good with easy instructions and color arrows on the platform to help ID all screws to be removed and all necessary Alan ranches were included (good quality tools). No other assembly is required, once the packaging is removed the printer is ready to be used. The printer can be ordered with optional 4 filament spools caddy to automatically change colors during printing. The printer is wifi capable and works with the latest wifi technology. At that point the user needs to install the mobile app and control the printer from the app. Very easy and straight forward process using QR codes to add the printer to your Anycubic account. Initially the controls were not as responsive, but once I installed the lates firmware (don't skip this, well worth it!) controlling the printer was a breeze. The Anycubic app gives you access to thousands of ready objects to be printed. The graphics are fully searchable with key words. Selections can be saved for easy access later on. Once you select the graphic on the mobile app, you click "Print" directly from there, select the colors you want, and the printer starts working. If you order the optional 4 filament spools caddy, the printer will automatically change colors during printing. Their customer service is excellent. The first printer had an immediate malfunction in the filament cutter mechanism. The immediately refunded the printer and I ordered a new one. The second printer didn't have any issues.

What a disappointment this machine has been. I've spent more time playing repair technician than I have actually printing with this thing. I have nearly 8 years of 3d printing experience, have machines from multiple vendors, and have both Resin and Filament printers, so let's get that out of the way first. The first issue was a clogged nozzle right out of the box. And I know it wasn't me who clogged it because I was running white filament in the machine and when I finally got the nozzle unclogged, I got black filament blobs out of the nozzle. Tell me you QCed it badly without telling me you QCed the printer badly. This machine was sealed up tight in the factory packaging, it wasn't an open box and showed NO signs of having been opened previously, yet somehow there was black filament in the hot end before I even ran it the first time. Even after clearing it, the clogging didn't stop. Couldn't order a nozzle from Anycubic because they were out of stock and stated lead times were MONTHS out. So, I took a wild chance on a recommended after market nozzle and VOILA! Problem solved. Then there was the bed adhesion issues. The build plate that comes with the machine is akin to tarpaper wrapped around a thin steel sheet. It's aweful. I cleaned and washed this thing multiple times, left the door open, left the top off, and still couldn't get good adhesion consistently. PLA was warping up on the corners, or sliding free and the nozzle was grabbing it and dragging it around the machine. Replaced the print bed, again with an aftermarket replacement, and again, VOILA fixed. Fit and finish on this thing is confusing at best. I had to tighten screws on the extruder housing that were loose from the factory, the front door and top are flimsy acrylic (and no, that's not a reasonable cost savings since Elegoo managed to get glass on theirs for $300 retail price). The ACE Pro is probably the worst designed contraption I've ever seen. I can't even begin to go into the amount of issues I've had with this thing in the space of an interview, but here are a few that have caused me to have to COMPLETELY disassemble the unit and replace parts Anycubic had to send to me: - Filament jammed in the inlet, wrapped itself around the bottom of the housing and fetched the entire thing up. - Filament got jammed in the buffer multiple times and bunched up so badly that it exploded one of the mechanisms from the pressure - The filament feed sensor failed on 2 different slots and had to be replaced - The filament buffer circuit board had to be replaced due to failure - The buffer has had to be replaced twice on one ACE unit and once on a second one At one point, anycubic replaced a spool of filament that kept jamming in the unit because it was a cardboard spool, so they replaced it with a plastic spool version. They advised me NOT to run cardboard spools (even though the majority of their filament ships on cardboard spools) They advised me not to use matte filament, filament on cardboard spools, silky filament, or anything other than their PLA on plastic spools. I've had this thing completely apart to replace parts at least 6 times at this point. I have finally been able to order factory nozzles from Anycubic and noticed that they have changed the design. The previous design had a brass throat through the heat sync that contained a teflon tube inside the throat. The new version is all metal with NO teflon tube inside. I suspect that this is what was causing a good majority of the clogs and jams, especially if the PTFE tube at the top of the extruder housing was not seated PERFECTLY against the throat of the nozzle. I have also learned that since I bought mine, just a few months ago, they have replaced gears and parts in the extruder housing with newer metal versions. So if you have an issue (or I should say when you have an issue) that causes them to replace it, you will get the new version. One quick tip for WHEN the machine jams filament in the buffer of the ACE Pro. When you pull the housing off the main unit, flip it over and look at the feed tubes coming from the filament loading mechanism and run to the inlet of the buffer. They will be "pinched" in little molded plastic holddowns inside the machine. I am convinced that this is pinching the PTFE tubes to the point that filament that is already traveling through multiple potential points of failure is meeting too much friction at this pinch point. Lift the tubes up so they are not pinched inside those hold downs. If you are worried about the tubes moving or shifting, use some electrical tape to hold them down lightly without pinching the tubes and restricting the filament path. I will say that their support people have been great, and usually get parts out to me quickly, but the fact that it even has to happen with a machine that is only a few months old is nuts. All in all, I would not buy this machine again, and in fact, they only got 2 stars because of how responsive their customer support has been.

The Anycubic Kobra S1 Combo is my first 3D printer and I am impressed with smooth operation and reliable performance. I love that it has a camera on the inside so I can watch my prints as they are being made. The multicolor printing feature is a great addition, and the enclosed design helps produce consistent results. Easy to use and a great upgrade for creators. Good value for the money for first time 3d printer. The filament feed runs smoothly avoiding any clogging in the system.

I really wanted to like this printer, but it has been a huge disappointment. Since I bought it, I have had constant problems: filament jams, clogs, random errors, and repeated situations where I had to open the print head just to get it working again. It has felt more like repairing a machine than actually using one. It has also been very unreliable on long prints. I had a print that was supposed to take about 3 days, and it shifted around 60% through the job, ruining the entire thing and wasting a lot of time and material. The multi-color system has been even worse. It wastes a huge amount of filament, and my latest issue has made it almost unusable for what I need. The printer completes the first layer correctly, even with multiple color changes, but when it starts moving to the second layer, it just freezes. There is no proper error message. The machine stays on, the fans keep running, and it looks like it is still printing, but it does nothing. I have not been able to solve this. What makes it even more frustrating is that I paid a lot to bring this printer to Colombia, so this was not a cheap purchase. For the price, I expected something far more reliable. Instead, it has been a constant source of wasted time, wasted filament, and frustration. Based on my experience, I would not recommend this printer at all.

I had high hopes for this printer. The prints are decent but not as great as i thought they should be. also on anycubics website it markets this printer having auto bed leveling and automatic z offset, i had to adjust and shim my printer bed cause it was to far out of level for the printer to auto level the bed. Which to me kinda defeats the purpose of the auto leveling a little bit but once i shimmed the corner of the bed up it does work now. But the automatic z off set has never worked and i have had to manually set it my self and change it depending on what type of filament i am using. Also the Ace pro version 1 that comes with the printer is not the best. it constantly has issue feeding the filament into the machine. if there is any resistance at all the slightest amount will stop the machine from being able to feed the filament. also mine came messed up and anycubic has had to send me a large part that requires taking apart the entire ace pro machine cause the filament in the number 2 spot would not feed no matter what i tried. Being a brand new printer i think they should have replaced the system instead of me having to play mechanic for them on a brand new machine that came broken. would have been different if it worked then stopped working but it was a issue right out of the box. I have also purchased the kobra x and the prints are amazing but being a bed slinger i would have thought the prints on the s1 would have been better. The selling point for me was it came with the ace pro that also acts as a drier for drying filament. if you need a printer that is fully enclosed to print certain types of filament or a system that can dry your filament while printing then i do think this could be a good option for it does do a decent job at printing. I do think they should ship the combo with the new ace pro 2 that i believe from what i read is compatible with the s1 and the x. but the one that comes with it is the ace pro version 1 which isn't near as good and also isn't compatible with some of other printers. I had bought the kobra x before doing my research and was in hopes the ace pro would also work with it that came with the s1 but it does not. I do have to say as far as service support Anycubic was extremely quick to get back to me and fairly quick at shipping and sending the replacement parts that was needed to fix the machine. i have not had time to replace the part to see if it fixes my filament not feeding on the number 2 spot but I am in hopes that it will. But i still think they should have replaced the machine sense it was a issue right out of the box and not have me have to completely tear apart the machine in hopes i do not cause more issues, create other issues, or make it worse.
