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 scrapped 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.

This is my second S1 and first with an ACE. I already have two Bambu Lab printers. I was so happy with the S1 that I got this one instead of committing further to the Bambu Lab ecosysem.Set up is really easy if you can follow the directions and basically prints perfect right out of the box.The biggest thing for me is the consistent quality of the prints. I haven't yet had a badly failed print that I didn't cause myself. This is by far a better value than the A1 in at around the same price. The Core XY means really consistent prints at higher speeds than possible on a bed slinger since your print isn't flying back and forth at high speeds. The ACE has been great so far on the few prints I've done with it, and I like how much easier it is to load filament over the AMS lite from Bambu Lab. I also like the small footprint and the overall look of it. The only thing I'd change is to make the front panel clear rather than smokey so I can see the progress at a glance. Since I only print in PLA I'm toying with the idea of just removing the doors completely.Anycubic is new so there are some trade offs that I didn't expect coming from the Bambu Lab A1. Namely getting parts is slow so order replacement nozzles and stuff long before you actually need them. Also the firmware out of the box is bad. Really bad. Lots of connectivity issues and it's riddled with poor spelling and grammar. These are minor as they have already improved a lot in the latest releases and they will likely improve further. And finally the printer is slow to start... it spends a lot of time leveling and preheating before getting to that all important first layer, but the annoying thing about the pre start is that you can't cancel it until it actually starts. So when I send a job and have that "oh crap I forgot something moment" you're stuck waiting.Overall I am very happy with the printer and hope that it has the longevity and reliability that I need.

Nice machine. Not super quiet but quiet enough to have in a hobby room. There is a bit of a learning curve to the app, though, and it only slices for PLA. I’ve run it almost 300 hours. I’ve had a couple warranty issues, but support is responsive (on China’s business schedule). VERY VERY MUCH appreciate the plug and play quickness to setup. Hint: use Anycubicslicer for filaments other than PLA to control temperatures supports & speeds

This is a great printer especially, as my introduction into 3D printing. It’s easy use out of the box but provides the functionality to improve my skills as I learn more. The quality of prints are outstanding. As someone new to 3D printing, this offers exactly what I wanted and much more for a great price point.
