Welcome back to Aurora Tech Channel. There are quite a lot of new 3D printers flooding the market this year, most of them being Cartesian bed slingers. Personally, I prefer to have a box frame with CoreXY kinematics as it provides smoother motion on the X and Y axis and a more stable Z-axis compared to a bed slinger, as its print bed only moves up and down.
Today, I will review the Flying Bear Reborn 2, which is a CoreXY with linear rails on the X and Y-Axis and linear rods on the dual Z-axis. The timing belt on the CoreXY axis is 10mm instead of the regular 6mm you see on most 3D printers, and all stepper motors on the X,Y and Z axis are 0.9 degrees instead of the standard 1.8 degrees. The print volume is 325*325*350mm, and it has a dual-gear direct drive extruder with a 1:7.5 gear ratio. The maximum nozzle temperature is 350C, it has a dual-part cooling fan and it uses an AC-heated glass bed. It’s a fully enclosed printer with 3 plastic boards on all 3 sides, a set of acrylic doors, and an insulation tent on top.
It runs an MKS Nano 6 motherboard with TMC2209 silent stepper drivers, a 3.5-inch touch screen, and inductive limit switches on the X, Y, and Z-axis. Flying Bear claims that this printer can print at a maximum of 150mm/s with a normal printing speed of 80mm/s with 1500mm/s² acceleration. Overall, for around $500, the specs of this printer look pretty good. I would like to thank Flying Bear for sending me this machine to review, and with that, let’s get started.

What would be cool is if you did an upgrade video. Frist with just adding a bltouch and new fw. And then an ultimate upgrade video the bltouch and klipper install.
I would also like to see this!
But these are things that already exist and people use. Would it probably be superfluous? i don't know
very interesting.. one for the shortlist. im guessing with klipper installed speeds can be seriously increased on this printer.
I was going to say this is definitely a candidate for a Klipper install.
I think I will get one and do just that!
Did you do that? Whats the result?
Great review as usual Aurora, unfortunately it's already out of stock here in the USA. It will be interesting to see when it's available again. Their Ghost 6 printer looks interesting as well.
Love the content and quality of your work. For me, visiting your channel is part of my CZcams routine when checking out all things 3D printing. Aurora Tech, Proper Printing, CNC Kitchen, Chris’s Basement, Teaching Tech, Thomas Sanladerer, and 3D Printing Nerd are my must visit channels. Thanks again for all you do for our community 😊
Thanks for names to check out. This is my favorite channel so far
FINALLY someone in the youtube 3d printer community that reviews coreXY enclosed printers... other than the bambu lab X1. So tired so seeing yet another cheap i3 style printer.
Propbably one of the best channels right now for thorough reviews and helpful hints for 3D printing.
Wonderful review, concise and very relevant insight. Great information. Thank you all so much, Dennis
Looks interesting. Great review as always.
Your channel is very quickly becoming the "go to" channel for 3d printer review and discussion. Keep up the amazing work you guys are doing.
Thanks for your work. Hope your channel growing fast.
Another excellent, no-nonsense review. Keep up the great work!
I just found your channel yesterday when searching for a review on the Flying Bear Reborn 2. Excellent work! Thank you for spending the time to review so thoroughly and especially printing benchmarks plus multiple materials. I also learned about changing the axis scale in the firmware. Thank you!
Thank you so much my dear, I am seriously thinking about one of these for Christmas now, great review!
Thanks. You two never let us down.
Thanks for your job, you bring us many detailled videos about ptinters, hardware and electronics included, and have many references to compare to. Your works is much appreciated, keep bringing on new stuff with your brother :)
Quick, simple yet detailed review. I absolutely loved it! Been looking to get into 3D printing for a few weeks now and videos like these are exactly the type I am looking for. I hope your channel gets a lot more attention because you guys deserve it. :)
Interesting printer
Great video as always
Thanks for sharing 🙂
I just discovered you today but I can't tell you how just how impressed I am with your videos so far. Much more relaxed and still super informative. Thank you so much for putting in this much effort!
I have really enjoyed your reviews. You are very detailed and you have a very good knowledge base. I loved your ender 3 s1 pro video and ended up buying one your review being the deciding factor. Keep it up!
Nice review as always young lady. Your reviews are some of the most concise ones I have seen. Keep up the good work.
This looks like a really comfy and competetive package!
The limit switches are mentioned as inductive but I believe they are actually optical limit switches.
Yes, they definitely look like optical switches.
Yes, you are right, they are optical limit switches.
Well done girl! Very nice review. I just ordered this printer few days ago, and now you just got a sub :). Kudos!
Great review!
I am blown away by how well spoken and informative your videos are. I just purchased our 12 and 18 year old their first 3D Printer (Ender 3 V2 Neo) for Christmas this year. We look forward to continuing to watch your videos.
Great technical review, can't wait to see where this channel grows
Just came across your channel. Enjoyed the content and your own perspective style. Looking forward to perusing through your past content and any new future content. Subscribed.
Great review, thanks!
Excellent review. I just stumbled into your channel. You are up to point and no nonsense. Subscribed
wow, your test Videos are so good. You even pointet out problems with aquering cheap replacements. Totally underrated channel, I hope you'll earn many subscirbers!
I know what to expect on your channel and always click like as soon as I start watching.
No need to wait.
Great reviews
I think your channel are some of the best 3d printing channels on youtube, you do such thorough and easy to understand videos, unlike some other channels
You are a very impressive, great review, the editing amazing, it makes the assembly so effortless, great job!!
Omg, you can fit in it, so cute!
I am a novice and wanted to jump into the 3d printing foray, but I had no idea how to start. I just found your channel and videography and professionalism was impressive. I had to subscribe and hope to see your channel grow. This printer may be a great starter as the price point is in my budget. Thank you for your dedication and hard work. It is greatly appreciated.
Hi Aurora, another solid and informative review, as always👍Not a make of 3D printer I have come across before and to be honest not one I would look to buy😀However, following your review and demonstration I am sure anyone looking for one of these printers will be off to buy one shortly😀You are an amazingly talented young lady, your Mum & Dad must be very proud❤️Keep up the great work😀👍
Impressive results and again thank you for the detailed review. Looks like a printer. 🇺🇸💪
Nice review as always. Glad to see an affordable XY-core printer. May be it replaces my Prusa MK3S. Thank you!
That moment when the reviewer could actually fit inside the 3d printer's build area...
Lol
Just like coupes with small back seats, the reviewer must test out whether they fit, for everyone's entertai- err, information
Another great review. Love your "Cons" section has suggestions, or workarounds to reduce possible annoyances.
Nice video!
Thanks a lot for your excellent review. This printer is very interesting.
Another great video - absolutely turning into my favourite trusted source for reviews on 3D printers. Love your analytical approach to testing and putting the printers through their paces.
What would say is your favourite printer of 2022 so far?
I absolutely agree. Admittedly I was led astray initially by my assumption that your age would mean that you knowledge and understanding wouldn't be sufficient, however I was completely wrong. You really do have, in my opinion, the best, most thorough and succinct 3d printer reviews available that both give a comprehensive overview of features whilst highlighting flaws and giving acceptable resolutions
For me, my go to printers are BambuLab X1C and FLSUN V400, just because they print fast. When they are in use, I will use Creality(S1, S1 Pro, S1 Max or CR-10 Smart Pro, or any Creality that uses a Sprite extruder) or Prusa (MK3S+, Mini+). I guess I will also add this new Flying bear reborn 2 as well.
@@AuroraTech Thanks for the reply. I have the X1C on pre-order at the moment and very much enjoyed your review on that one (was how I found your channel) - a lot of the other YT reviewers do a lot of "marketing hype" whereas yours was much more about how the printer stood against it's peers in the marketplace
TY!
Fantastic video! I'd just settled on getting a Sidewinder X2 and now am seriously thinking of this instead...
Thanks for this! Great for those of us that just can't get excited about building a Voron parts Kit.
I'm thinking this printer may not be a bad choice to print parts for a future Voron build.
nice machine
You do such a great jobs on your vids. The most informative reviews on CZcams. Would love to see a tour of your shop and all your printers. Future vid.idea. :)
The glass bed observation is important. If you can't detach the bed to get a print off of it, it will make the BL Touch absolutely useless and you can expect continuous re-leveling due to the jolting
Very kool looking , i just ordered the V400, might get this one too
Love you and your videos! Very professional and informative. Clearly, this printer is not for a true beginner like me. I will need to have a fully plug-and-play unit. Watching you make all these updates to settings and Gcode are not for people like me. Thanks for your professional presentation, Keep up the good work!
This looks like a nice printer for the price, and it's a brand that I hadn't heard of. Thanks for the great review.
Not inductive, but optical switches. Revert step per mm to 800 as that's the correct value. Height error likely comes from first level thickness (adjust z-offset), or from garbage on the last layer. Print a part with skirt or brim and measure brim thickness afterwards. It should be the same as your first layer height. Irregularities on the top layer could be caused by over-extrusion. Print a solid object but slice with single wall and 0% infill, then measure actual wall thickness and adjust extrusion multiplier - this is filament specific unfortunately so repeat for each new spool.
The misspelled "Emergemcy" kills me! 😆
End of October is here!! Happy halloween🎃 with the Halloween themed flying bear printer! Great review!
Interesting, hadn't heard of this one! I like the "Emergemcy" button on the touch screen 😆
Great review. Its really good to see a review from someone who obviously knows there stuff.
really promising printer, thanks for the thorough review ! How are the noise levels?
Looked like there was ringing in most of the parts?? Definitely need klipper to get things going better. Seems like a solid machine. It wouldn't take too much to make it even better. Great review
Outstanding work as always. This printer seems like a solid value. These days it seems like Klipper and bed level sensors should be standard and I'd definitely use larger extrusion if I were designing a printer myself but all these changes would increase the cost as well. It'd be really interesting to see an end-of-the-year comparison vs other printers in the same price range.
I am a Fan. I often use a wood chisel not the putty knife to loosen bed and prints with care, unless glass. Also on bed leveling, if I want a little more squish to the bed surface I preheat the nozzle and us a thermal print paper from a grocery or general store receipt paper. The paper turns black and pulls a nice width as I pull it out from between the 2 surfaces. Often not having to use any adhesives. But glue stick and (Aqua Net - tried others with poor results) hair spray are used if need be. Washing the hair spray with water cleans it well. And Alcohol/air heat gun to clean any other surface adhesives if needed. Oh had to use a heat gun and a chunk of FDM to remove the print material on a textured surface when the first layer was to tight. Learned the hard way...
Love watching you explain 3D printers I'm amazed what they do 😁🥰 is there plans to review any filament driers?
I reviewed the Sovol dryer in the past, in fact, most dryers around $50-60 are the same, max temp 50-55C, OK for PLA, PETG, but not useful at all for Nylon which requires 90C, I ended up using a $60 small oven for drying Nylon, it works better than any filament dryer :)
@@AuroraTech thank you very much I was having trouble finding one which works 💪
A very competent and informative review. I wonder, how the cooling of the electronics is solved, as it seems to be inside the enclosure and temperature (as you mentioned) might reach the 50 degrees in summer. Have the cooling air streams (for the controllers, etc.) access to fresh air from outside?
Great review, glad I found this channel.
If one was looking at this or an Ender 5 Plus would you have a recommendation if both had a sufficient build size.
Hi aurora! I love your channel, I’m one of the silent viewers that follows you but almost never comments. I bought this 3d printer (which I didn’t know it came out) because of you, tomorrow it will be here. I was searching an alternative to the Voron Trident, as I don’t have the time to build it, and also since 3d printing it’s only an hobby, I didn’t want to spend more than double I payed for the Reborn 2 (I got it for 450€, which i think it’s a really nice deal). I think adding auto bed leveling and Klipper would make it a very good machine. Have you some plans to do an upgrade series on this machine? Thank you for your time and dedication and sorry if I made some mistakes but I’m from Italy and I’m not very good in English!
A removable bed is a must for me. Other then that good specs!
Great review, especially about the headed bed & trying all those different kinds of filament! Great contender to replace Ender 5+. Do you know anything about the nozzle, swappable, proprietary?
Another great review! And yet another not ready for prime time printer hits the market. Can you review the FLsun v400? And perhaps compare that to the prusa enclosed delta printer?
Wishlist for this printer:
Klipper by default.
Flex build plate.
3 z-screws so you can implement proper auto-bed-leveling.
Saw your reply about changing the mainboard to a BTT M8p. I find the M8P but not the CP1.... Did you mean CB1 using the BTT Pi4 adapter?? Great review!!
Hello. You are one of the best. I advertise you, on all the blogs that I subscribe to. English, Ukrainian, Russian. I'm waiting for my friend to be able to speak French Spanish. Thank you for your work
This seems like a great deal, get klipper on that beast!
Big extrusion gears! A nice feature. However the extruder is plastic.
Thick glass bed is great. It should be easy to level. You can simply put a PEI sheet on top, and lose 5mm in Z, which is not a problem. 330mm^2 PEI is hard to find though.
Please try to use the V400 speeder pad on these cheap CoreXY printers. They might be transformed into great farm machines.
Thank you for the exceptional video on the Flying Bear R2. I was wondering, regarding the AC heated bed, if you used 110 or 220 volts to heat it?
Hi Aurora, your video as usual are extremely clear and complete.
I do not know if you can give some suggestions but I have little trouble making reborn 2 working with klipper. All apparently look fine and homing works well. but when I try to move the axis Y or X independently, they instead move together, as result the toolhead movement is fault. I've checked stepper motor directions in the print.cfg and all seems OK. Also, with the original marlin firmware cinematic works perfectly, so i'd exclude any mechanical issue. would you have any clue? thanks!
As usual your channel is outstanding. When I read your title I could of sworn my mind translated my visual input to Flying Pig and it didn't help seeing the top cover picture with the Flying Bear. And you are right a plexi top that didn't bubble up so high would of been a better choice. Thank you both for your time and work.
The Pope-Mitra is legendary! 😂 Very good printer imho.
Everyone should wait a few more month i think. There such a huge jump in the printers offers
really nice review and very complet :) do you prefer this printer or the Sapphire plus ? a versus will be cool. Thanks for your job.
It will never freak me out how young you are. This printer is excellent though. Even if i currently have no use its definitely where the 3dp market needs to go
I know this is a strange place to ask, but I got the Reborn 2 this weekend as my first CoreXY. Everthing seems to work fine, but I'm confused by one thing and couldn't find an answer so far.
I get a noisy resonance when the head is moving on the Y-Axis. The movement on the X-Axis is clean. I can even feel the difference when moving the head by hand. As the gantry was pre built I have no idea what to look for.
Maybee loosen the screws where the gantry is mounted on the Z beams and retighten it? My thought here is, that there might be to much force on the gantry on the sides.
Would love to see videos detailing the mods you make to this machine going forward. It looks to be a solid platform for modding into an even more capable machine than it already is.
Have you considered converting to one of the BTT pro boards with TMC 5160 48v drivers? You can get a buck converter to drop the 48v power supply down to 24v to run the fans, hotend, CPU etc. 48v would give a significant performance boost to everything including the extruder. which would be needed to keep up with the added speed. Going 48v on a bed flinger seems like a waste, but on this machine with that beefy belt, it seems like just the ticket. Just be sure to get the high voltage versions of those drivers instead of the neutered variety... Couple that with a Klipper install with input shaping etc and you will have an absolute beast of a printer.
nice price, I would start with a magnetic springsteel sheet on top of the glass though. I can only find a 310mm x 310mm sheet.
Seems like a lot of printer for the money. Not Voron speed but at less than 1/3 the final cost it seems like a great deal. Misses a few small points but gets the major ones very well and seems to print very well.
Hello could you share cura profiles? And printer setting screen shot?
Today unless the printer is Klipper enabled they are too slow.
Also, slicers like Orca run seamless with Klipper.
Thanks tor your efforts.
Cheers.
Looking to get a decent 3d printer on Black Friday so wondering what would be best. This or the magician pro?
May I ask your opinion for an optimal printer & user friendly CAD system for production parts? Part will be made from nylon carbon fiber & the parts are smaller than the size of 3 poker chips stacked? I will array on table multiple parts at once.
LOVE YOUR CHANNEL!
Thanks!
nice video! how about doing a low cost Bambu X1Carbon alternative video? Enclosed. Core XY only, high temp, at least 256 cubed or larger, great print quality and not terribly slow, is there a good alternative to save some money? perhaps also compare the mosaic palette to the AMS on the bambu to explore pros and cons of each.
@Aurora Tech, looking at the firmware, it uses a PT1000 from E3D, which is rated for 500C. That's why it's so high in the firmware, really it should be 515 because of the thermal max, or with your change, 365. NOt sure about the bed, though. I bought one from their Ali store since it was cheaper during the 11.11 sale + Rakuten than what's linked. Will look at the bed when I get it
Afferin Sana My Beautiful Daughter If I Had A Daughter Like You I Would Love It🤗
Another great video. Thank y'all.
Question. Is there an easy way to tension the belts on this machine?
No, like most other CoreXY printers, you need to cut the belt and re-tighten it to adjust tension.
@@AuroraTech well I can't deduct any points since it's the same way everywhere we look. But it would have been nice.
What do you think of this for a first 3D printer? Seems to have everything at this price point
Great review Aurora, can you also please review the Flying Bear Aone 2 3D Printer? 😊
I will be reviewing a similar one, the Kingroon KP3S Pro in December, but we may not have time to review their Aone 2 as our schedule is overloaded.
When you review the KP3S Pro could you compare it to the Tronxy Crux 1 and maybe the Creality Ender 2 Pro? Thank you 😊
Would love to see this with Klipper
I received a reply from a CZcamsr in the U.K. on a comment I left on his video. He said the Ender S1 was a real BED SLINGER. I didn't know what that meant until I saw this video of Aurora using the same term. Now I get it. :)
wow, just got this machine, total newbie to printing. Was with you until openonfig h? how where when?
Would it be easy to install klipper on this and have something like the sonic pad as klipper screen?
it's a STM chip so it should be. Also it seems to be using a Pt1000 or 100, could definitely have the hotend temp at 400 ish
