Anycubic Kobra S1 Combo 3D Printer, 4 Stunning Multicolor with Anycubic ACE PRO, 600mm/s High Speed and 320℃ Hotend Free-Clog Extruder, Intelligent Drying While Printing, Built-in Camera 250*250*250mm

Prior to this purchase, I have been using my Creality CR6-SE for 4-5 years with great success, but I wanted to start doing multi-color printing. Like many of you, I read some worrisome reviews and held off buying the Anycubic Kobra S1 Combo until just recently. Now that I've used it for a few weeks, including doing multi-color printing of my own (Openscad-based) designs, I thought I'd write a review and let you know I find this printer to work wonderfully with PETG (which is what I always use).Mine was delivered by Amazon's "heavy item" team and arrived in great shape. No dents or other issues. Assembly was easy and I took my time to make sure I did it all correctly. I felt the instructions were clear and adequate.My first prints of the Benchy failed due to poor bed adhesion, but I then washed the bed with Dawn detergent and hot water and haven't had any issues since. I do wash the bed now and then, just to be safe.I've printed some pretty challenging, small, multi-color keycaps that really came out great. See photo. These have very fine text lines that need good bed adhesion and I'm very impressed with the results. I've also printed some large items (adapters for small 250g reels) and didn't have any warping or lifting (with brims turned off). The ACE Pro has worked well with cardboard reels so far, but I do intend to print the thin plastic "rims" to avoid the potential of cardboard dust creating some issue down-the-road.Some people have complained about this or that, but I think it's easy to configure the ACE Pro with generic filaments and you can also set the order the colors are printed in the slicer and adjust the purge waste. There are two places you set the bed type. The first one seems stuck on "Smooth Plate", but scrolling down there is another place to select "Textured PEI". I adjust PETG to print at 240C rather than their default 230C which seems a bit too cool in my experience.I have found the bed-levelling to work well almost every time. Strangely, a couple times it somehow started with "zero" Z so that the nozzle basically scraped the build plate, but did no harm. I can't explain how/why this can happen, but it did. I just aborted the print and restarted and the auto-leveling worked fine on the second try.I certainly suggest you monitor your print jobs as they start and see that all is well. When you gain more experience with your machine then you might launch print jobs remotely with your phone, but that's not my workflow.BTW, I don't use Anycubic cloud service to print. The Anycubic Next slicer is able to connect to my home Wi-Fi network and I can submit print jobs directly from the slicer.So, this is a great printer and seems really well built to me. I'm fine with the clear/lexan/lucite door and top cover. Glass would have just made the machine even heavier.Also, I've directly compared prints from the Kobra S1 Pro and a Bambu Labs and I'd say they're equivalent.

The reason I give 4 stars originally is I had received this printer that day and it's missing a few screws the build plate is damaged where it looks like the print head had contacted it. I know it has two sides but getting a newish machine this is sad. I am missing one blue lock which I have those. The main feed line had filament and the head was clogged. I have no idea what had happened to the power cords but they are missing the grounding part of the power cords. I don't want to sound negative, I do really like the brand. I do have other anycubic resin printer and wash and cure 3. No issues. I try to print my first print and found the print head tip was floppy so I removed the cover and silicone sock and found the assembly was broken just below the heat sink and it looks like the part was damaged with pliers. Even if I have to buy a new print head/ heat sink assembly I do like how there is plugs so the whole cable don't need to be un routed and re strung disassembling the whole machine like I had to with my ender 3. I do like the build quality otherwise my pettyish issues and know that I didn't spend the 700 plus dollars so it may be refurbished. The head and pei bed plate damaged is sad but I do see a lot of potential. Even though my first print after installing the new hot end assembly had failed i see the intermittent 40-60mm/sec. And then when I see the detail of what is being printed I am feeling a whole lot better. I recommend all anycubic things I had played with so far. As hard as I had tried to make this thing work I had to return because no matter what I had tried this device would not do anything consistently. I think out of a dozen or so attempts I got 2 benchy. I wanted this to work but when you received a return for nearly 700 and it was damaged like it was this was a red hand from the start. I am somewhat disappointed with fdm at this time. I still think my 40 dollar anycubic photon mono 2 that I bought on Facebook market place is the best printer I had experienced. I had returned this and mabe in the future I may try again with the fdm setup.

The Anycubic Kobra S1 has been a big step up for me coming from older machines. Unboxing took some time — most of the instructions are actually about carefully removing and unlocking everything packed inside. I also bought the version with the 4-color add-on, which was secured inside the machine. It’s impressive how well they fit everything in one box, but expect setup to take a few hours rather than the quick start the manual suggests.Build quality is outstanding and a huge improvement over my older XYZ and Monoprice printers. Once assembled and you get familiar with a few small nuances, it’s very easy to use. The phone and PC apps make it simple to browse thousands of premade models and start prints quickly.Print quality is top notch. I’ve logged about 300 hours without a failed print yet. Speed is solid as well, though multi-color printing slows things down since each color switch adds time and waste. If your project allows layers of a single color in sequence, it helps minimize both.The printer is quiet, reliable, and large enough to handle up to ~11" objects on the diagonal — plenty of room for most projects. Maintenance is minimal, usually just wiping the plate with an alcohol wipe before each run. One quirk: the machine “poops” a bit of filament out the back each time it primes. Luckily, a free “poop chute” design is available in the app to redirect the scraps.Overall, the Anycubic Kobra S1 is well worth the price. The combination of build quality, print reliability, and ease of use make it an excellent choice for anyone looking to step up from older entry-level printers, though keep in mind that multi-color printing trades efficiency for aesthetics. Strongly recommended.
