Most buy/build as you go projects are never as good as just buying the higher end thing outright, but the Ender continues to be an exception. You could go from a $200 printer to a $2,000 printer, and it would still be extremely competitive. Love it.
While I congratulate the designers for doing a nice job of turning a Ender 3 into an CoreXY printer, I wonder if this kit will be sold very well. The cost is a big factor here. While I certainly agree that the components, design and support are worth the money, I really doubt that Ender 3 users will feel the urge to buy this kit. Do not forget that the Ender 3 fares well because it's a good and especially relatively cheap printer. Personally I think that a CoreXY conversion kit for the Ender 5 would be a better marketable product. That printer already has the main base frame in place, so a conversion kit could not only be cheaper, but also more in the price range Ender 5 buyers can afford. I think most Ender 5 users would love to have a conversion to dual lead screws and CoreXY.
@@TeachingTech That's good news. I hope we get some more information about that in the coming months. I already own the standard Ender 5 (next to the Ender 3), and I am in the process of exchanging my standard main board for a SKR mini E3 V1.2. Now I only have to compile new firmware to use Marlin 2.0 using Visual Studio Code. That should be no problem. By the way - Maybe it be a good idea to to make a video for newcomers how to use the latest Marlin 2.0 and how to install and use Visual Studio Code? It's not very complicated, but I guess an "newbie" could easily be lost.
@Furry Catfish Fillet yeah, I thought it wad interesting that creality went to all that trouble and decided not to make it corexy. Maybe in the future.
It’s true that you could make a hyper cube for less than this, but what I like about it is all the metal components. It looks like it makes quality prints, as long as the extruder gets sorted. Honestly, if you’re going for speed then you need a strong dual drive extruder anyway.
We just released a dual gear printable extruder that uses BMG components. Fits onto the hotend like a glove. This will address the underextrustion issues. Also, thank you for appreciating the all metal parts. Not many people notice them. Your encouragement means a lot to us! :)
Furkan biçer well the ender 3 performs just as good as the core XY setup For that price you can just buy two additional ender 3s and print 1 or 2 times as fast
This seems like a fix for a problem that really never existed. I'm all for tinkering and redoing things, but this just seems.....I dunno....not...not a worthwhile "upgrade".
I agree, it looks like you would lose compatibility with other modifications and upgrades, and the kit itself costs as much as an ender 5 or a similar corexy printer
I kinda agree, but as Michael said, it's more about the project then the end product (at least that's how I'm interpretating his statement). Personally if/when I go CoreXY, I would rather go with a Hypercube Evolution or a SecKit SK-Go, a little bit more expensive, but build from the ground up to be a good CoreXY printer.
Where I live you can buy Ender 3's for 160 euro, so two Ender 3's delivered with glass beds and even two direct drive upgrades for the price of this upgrade kit (+ import duties)... What would be faster? 1 Ender 3 CoreXY upgraded machine or 3 Ender 3's printing at the same time?... This kit really doesn't make much sense...
It's worth noting that when you've got a rectangle, the easiest way to ensure that it's actually a rectangle rather than something else, is to measure the diagonals. If they aren't equal, you've know that something has gone askew and will need to be addressed.
I understand the price complaint. However, I love this idea of this kit. This kit can feed the upgrade and build itch that many of us have. Its not flawless and that, to me, also provides room for some personal ingenuity for improvements. I love my Ender3 and I love the core xy concept as well (own a Railcore II ZL as well). I think the build could really benefit from an all metal hotend with a Zesty Nimble. It would give the build a very light direct extruder and eliminate the under extrusion issue. Great video Mike and thank you for sharing it with us. This just became one of my future builds.
Hi Sonny! ah i see a railcore owner! We actually took some ideas from the railcore when it came to getting the metal components made. Just that our belts don't cross so we're a little different there but each to their own; there are benefits to both. You're right, a flexible direct drive would really make the machine shine. Hopefully there can be a re-test with a better extruder.
This kit may have its place, but on a Cartesian E3P direct drive I can produce a 47min benchy that's as exact to the slicer preview as I can tell. Base speed of 140mm/s. The extra Z is nice but not at the expense of Y.
I appreciate the work you put into this .... just not sure Kay3D thought this one out very well as far as a viable market. “Kay3D are actually preoccupied with accomplishment. So they are focused on whether they can do something. They never stop to ask if they should do something.” - Dr. Ian Malcolm
You are a God when it comes to all the multidisciplinary aspects of this hobby. You should start your own company that uses corexy and targets the price point between 500 to 700usd. Not a speed demon ratrig but something that can do 300mms at standard quality
Saif Alshamsi better to build printer with changing beds (eg 2 beds sizes 200-200 and 350-350) I have tested if to install in ender 3 on the bed drive Moyer 48 size you can achieve speed up to 120mm per second!! So what is the need in corexy??
HI Zachary! Michael did do a fantastic review on the kit! It wasn't an easy kit to design but we're thankful for the feedback. Replacement parts are already on the way to Michael and they should solve the under extrusion issues
KAY3D Labs I love it I always like these kind of videos. Over the years I learned a lot about 3D printing and I learn and see every time new things to make beautiful upgrades. Maybe also for my channel as well.
Would it really? That would only save you a portion of the X motor weight, and that's already smaller and lighter than the Y motor, which is upsized specifically to handle the load. With CoreXY you still have that larger load for Y movements, but both X and Y motors must handle it.
When comparing benchy models most people always pass over 2 of the important parts that show a lot. The writing on the bottom and the back tell a lot about a print also.
@@____________________________.x I'm more of the right tool for the right job. Which is why I built the LayerFused X301. I just don't see the point in taking an existing tool and turning into a completely different tool. I personally feel like most ender printers come with a payment plan. You get the base unit then spend the next year upgrading it in one way or another until you have the printer you want. I did that with my ender myself and felt like once I was done I spent far more in upgrades than I did just buying the better printer from the start. Just my opinion.
@@QuantumRob-yt The whole point is the knowledge you gain and some people like tinkering. A hobby in general which this is not compatible with pinching pennies.
@@ljohnson9440 its a piece of shit. people need to realize for some people the hobby is fucking with the machine for others the hobby is actually the printed objects. tinkerers dont excuse a piss poor product.
the kit costs almost as much, as 2 ender 3's just to "upgrade" a allready well performing printer. it doesnt even increase buildspace. why would people buy something like this?!
Man, I feel bad for the people involved that feel that this is a commercial opportunity. While I'm sure they will sell a few units, I very much doubt the majority would pull the trigger on something like this. The Ender in itself is a 'hobbyist' printer, and largely purchased because people who want to buy it, want a cheap, decent, 3D printer. Not the mention the upgrade path involved, you would think they would at least provide some of the roller/pully components assembled. I just can't imagine who thought it was a good idea to spend 1-2 years developing this idea as a product, even just writing that ~260 page manual (lol)! With the Ender 6 (Enders new Core XY printer), hitting Kickstarter later this month --- ouch!
Don't feel bad for us mate. Every business starts from somewhere, just like yours. Some have a great start; some less than ideal. I cannot comment how much has pulled the trigger but we do have a backlog of orders making us ramp up manufacturing. This review has provided us with countless opportunities to improve; including making direct drive options available, printable cases available and other things. It has made us realise the loop holes of QC within the warehouse sorting area. As for the manual; it was deliberate. Surely, you can leave out the pictures and details and come complete with 2 pages, front and back. Surely you could; we've seen it like creality printers and so on and so fourth. But the manual includes the nitty gritty details including eccentric nuts, how to tighten them, why tighten them, a video link to watch if you don't like etc. In a CoreXY setup, you cannot just route a belt from A to B and use an idler bearing to tighten the belt. Every bearing and idler is stacked with appropriate spec'ed washer. Without a proper manual with details; a coreXY pulley system can be catastrophic. We studied the comments, the questions that people ask on common ender 3 groups on facbeook and realised repeated questions. All day everyday and that's when we decided to include this super detailed manual. While others may find it (lol!) like you did, we're sure others who appreciate details would appreciate the manual. I don't know if Creality has the same type of support; But I know we do. Maybe the Ender 6 is better; maybe our coreXY system is more sound; who knows? But I know that we don't need everyone to pull the trigger; just a small community that knows what they're doing and what they're getting into. CoreXY is a very, very intricate and complex system. A system that cannot be summed up in 19 minutes (like what Michael mentioned). It takes real details and real hours to assemble calibrate and print. This comment is getting a little too long but I just want to let you know that I appreciate your feedback :) Thanks bud.
sorry you had to see underextrusions. Hopefully the replacement parts will reach Michael soon enough and he can help do a re-test as the underextrusion issues should not happen
Damn that looks pretty great. Apart from the funky bowden path that seems to be fixable, I'm sure you could get much higher print speeds and better quality over stock easily with this kit.
Hi Mavamaarten! Indeed, the extrusions were sent wrongly. A little shy of 80mm. This made the bowden tube really compressed and the other things stick out. Hopefully Michael receives our replacements soon (we already shipped out) and can do more testings as under-extrusion should really not happen at all.
in the comment everyone trying to point out the lack of practicality, but the thing is these are really a toy and a hobby in part or in whole, and upgrades like these are things people do because they want to, not because they need to
Nice. But for less of the price of this expansion kit you get a complete CoreXY printer new. Like the Two Trees Sapphire Pro. Or cartesian direct extruders with auto bed leveling. And those already come with silent stepper drivers.
@@depreciated incorrect, the ender 4 was a true CoreXY. The Ender 5 is an Hbot, the X motor is moved back and forth by the Y gantry. Stationary motors and The belt path is what makes a CoreXY, which it had. Take a look...creality.com/creality-ender-4-3d-printer-p00245p1.html
Nice review! I wanted an Ender 2 because of its small footpirint, but Creality stoped selling them. So I thought of converting an (broken) Ender 3 to an Ender 2. Would be a nice project!
Agreed. If it came with dual extruder, at least there's some benefit over stock. But this kit is just stock function, no benefit at all. I bought BIBO2, does pretty much what this kit does + dual extruder + enclosed frame + laser etch for much cheaper when you consider your time.
Ender 3 is defo a gateway to the addicting and yet fun drug that is printing got a ender 3 mid of last year and for Christmas i just got a ender 6 core xy and dam is it fun now looking at a voron 2.4 for my end goal of a tinkering printer and maybe a Ender 5 plus just for my BIG things
Well seeing that the company folded. Is there a way tou could share the info on this? I have a CR10 I would like to do, and the info should be a good start.
We have a local 3d printer(s) with a slightly less volume (probably) but for nearly the same price (of Ender 3 + Kay3D kit) you get a fully working 3d "box" printer with really good characteristics. The main problem that I see here is that you need to make a conversion by yourself! It's a lot of work (for the most of users) so the price of the kit seems to be about 40-50% higher than it should be. Of course it's my subjective opinion and I can be wrong.
I've wanted to try a coreXY for some time due to the claimed speeds attainable, not sure this is the one though. Seems a bit steep for the result. I wish the company well though.
Looks like a well thought kit, minor issues as you stated. I do like all the aluminum brackets vs using acrylic ( they are aluminum, correct? ) My question is that after you correct the under extrusion issue , re-routing the bowden , how does it compare to the ender 5 with speed vs quality.
Hi @mark! If you don't mind, I'll like to explain that. The under extrusion was because the Z height extrusions were a little shy of 80mm. Therefore, bowden tube was compresssed, z rods and linear rods were also protruding. Replacements are already on the way and we're confident that, that should solve the under extrusion issues. Also, the brackets are indeed aluminium. Thick, reinformeced non-3mm brackets that are extra-heavy duty. Once can expect speed increases and stepping accuracy since hotend movements are controlled by 2 stepper drivers instead of 1. Hopefully Michael can give you a reply as well! Let me know if you need help with any other questions! :)
Hey Micheal ,BIGU have put out the SKR mini e3 V2.0 with easy sendorless homing , dual z support and thermiator ahprtage protection circuit , can you do a video going over and setting up the board and verifying the thermistor protection circuit?
If it added a direct drive or at least move to lineral rails I would be tempted but it would need these to be added for me to spend 300+ for this addon
I have a Ender 5 Plus and the kit for it is less expensive. It seems to make a lot more sense for a 5 which is already a box frame without the sliding bed. The question is how much faster can I print with the conversion?
I just went to buy one of these kits... they are in Singapore, and they wanted to sting me for $129 for shipping to Australia! AND no mention if the prices are in AU$ or US$? Still, your channel is my go to for all things 3d printing.
Michael, do you still have the manual and STL assemble gauge? I can't find anything online. Kicking myself for starting the build 3 years late. Alvin isn't replying to FB messages unfortunately. Thank you @@TeachingTech
I’ve been pleased with my CR10-S, for about the same $$. The print head or hot end moves along the X-axis just as much as it does when Z is 200mm. The “wobble”, seems to me, comes from the fact the Y-axis or bed is moving the tall print. I would think tuning the jerk, or running with S-curve moves would be about perfect w/ a Cartesian printer. You are adding complexity when it isn’t needed. In my never to be humbled opinion.
@@basementdwellR Wouldn't it be MUCH easier, cheaper and just generally nicer to sell the Ender 3 for 50,- or some low amount just to get rid of it and then buy a brand new CoreXY printer for less money than this entire kit costs anyway, spend the savings on some nice extra filament to play with a brand new and better printer?...
@@someguy4915 In short no, no it wouldn't. There is not one single proper functioning CoreXY that's worth it's money under €600 which is the lowest number I can build one (that is worth building) from scratch for. There are numerous viable builds out there (ratrig, BLV mgn, V-King, Hypercube Evolution and the list goes on) , but the usual supsects like Creality and Twotrees and what have you cannot supply you with one that's cheaper and does not require a whole bunch more money and work thrown at it. I mean you might as well just stick to an Ender 3 as then. I don't know how good this is either. This is not for me - I know who it's for though. It is a niche market as judging from the comments it's like 80% "ppffft why the hell do I need to pay $300 for this". CoreXY is the most robust motion system with the best possible POTENTIAL to produce high speed and high quality prints. If you've sank a bunch of money into your Ender 3 and realize its limitations, getting a functioning CoreXY out of it for €300 is a pretty good deal imho. This is not what I'd get though as it's too much of a compromise. I want a 3 motor Z at least for real proper mechanical bed levelling, I want a silent steppers and hiwin type linear rails. I want all the jazz. I also want a bed that's powered from 240V from the wall soket and suspended on a kinematic constraint system to be exact yet allow for expansion from heat without affecting Z whatsoever.
@@basementdwellR you sir, speak eloquently. Because we've studied what tronxy offers (which has been mentioned serveral times here), and the printed parts corexy machines, we went with laser cut metal plates and CNC parts to improve printing reliability. Thank you for believing that €300 is a pretty good deal. It's just a little disappointing people pit one product against another without consideration on the material used on parts, support available etc. We really appreciate your thoughts and comments on these. really.
One little comment: I'd unbox the kit and label those pieces first, in case something is missing. Not much point disassembling the old printer first if you can't complete the process of building the new one.
Spiffy kit, though "conversion" is a bit of an understatement. One thing I noticed is that the Z rails and screws seem a bit long. I don't see any logic in making them longer than the Z height of the frame.
Anyone else annoyed that you loose a bit of the XY print volume? But that 400mm Y is crazy. I think this kit would be worth it if they were able to keep all the motion hardware inside the frame to allow for an easy enclosure setup while keeping electronics outside and perhaps offering a kit upgrade option for walls or just specs to source your own. Also I would pay more for a linear rails option.
Wouldn't the under extrusion be quickly fixed with esteps adjustment? Seems like that should have been the first fix after the benchy... or is it wrong to think esteps would fix the under extrusion?
It depends on the cause of the underextrusion. The problem here is that the routing of the ptfe tube seems to cause a sort of "snagging" issue, which wouldn't be consistent
WOW, for that price you can buy a complete corexy.... I have 4 printers, the STOCK ender 3 pro (with capricorn and better springs) is literally one of the best printers you can buy.... But for $600 (or even another $400?!?!) you can but some pretty nice corexy printers.
Conflicted grate video as usual but seems to me a product no one was asking for especially at a price you can buy a real core XY ? Plus the fact you lose build plate area to me that's more important then gaining some extra height. For me your other ender3 extender video product is a better option. How about you do a DIY ender3 video where you get some 2040 extrusion new longer Z screw, cut it your self or precut and extend the Z axis it's a far cheaper option then all these and its easy to extend or make new leads for the X gantry?
That's a great question! We're in the works of retrofitting one of the existing tool changing solutions in the market into our corexy conversion kits on the ender 3 & 5 series (including 5 plus). On the E3 space is a little tight so maybe the number of tools will max out at 2. One of the problems with tool changing is that you usually need more Y space at the rear also. However, there is not ETA of the timeline available but we usually update from time to time on our progress! :)
It seems like Bowden tubes drag on the filament a bit and increase the load on the stepper. The alternative is to put the feed stepper on the moving parts, but that increases the mass of the gantry, reducing acceleration. Is it possible to "lube up" a Bowden tube somehow to reduce resistance without getting gunk on your hot end, and without contaminating the filament? If that's not practical, can you upgrade the stepper on the feeder and get more oomph out of it and increase extrusion force, increasing extrusion rate? That might require an upgraded hot end that can melt more material per second, but might be worth it. What do you think?
Did you run a skew test in the X and Y as this can occur if the dimensions are not perfectly aligned on a coreXY, or the belts are over tightened, the way to see if you have a skewing issue, is to look at the prints of holes, if they are relatively round your O.K. but if they are oval you have a skew issue in your gantry
You are creating great content to 3d community. Please use grey filament when printing test cubes or benches. There is a reason that most of the primers are in grey, they highlight imperfections. This lime green bench is worthless if we can not see anything.
i know i'm very late to the party, but i am going to hunt around and see if there are any build documents left that include dimensions so parts can be printed/cut. i have an ender 3 clone in pieces and want to build a 235mm^3 corexy printer out of it.
Just came across this video. It appears Kay3d has gone the way of the dodo. Any chance of getting a copy of the instructions/BOM? I’d be interested in seeing if I can source the parts myself.
great video, well engineered product but how is it better than an Ender 5 plus? for the same price you get massive print volume, bl-touch, silent board and touch screen. slap a capricorn and a decent extruder and you get an astonishing printer.
Did you miss the start of the video? This is more for someone who has an ender 3 cause that was his beginner printer and now would like a core xy. If someone only want one printer this is a cool option. Also saves one from having to go through the process of selling the old printer and picking a completly new one.
@@lukas1672 I have that Ender 3, like so many people and while I have done a few upgrades (most recent one I did was direct drive upgrade for instance) this kit makes no sense and solves no issue you'd really have... This kit does not increase build area which is a major disappointment. I'd much rather sell my Ender 3 to some kid for a low price and then buy a brand new printer with larger surface and Corexy design for a lower price than this entire kit, the money I would then save can go into filament... So relatively complicated and more expensive kit or brand new 'adventure' with a new printer which is cheaper anyway while making some kid happy with your old Ender 3, easy choice really. I applaud them for trying to make the Ender 3 corexy, I just really don't see why anyone would spend this much for such an upgrade on the Ender 3, this also seriously limits any options for increasing build area as you'd basically need to replace nearly all the parts of this kit again...
This is more "build a CoreXY printer with bits from an Ender 3". Which is pretty much what I did by buying 2 Ender 3 Pros to start from and not even assembling the second because buying the components you can use from an Ender 3 in a build cost quite a bit more separately than the 170€ I paid for my Ender 3 Pros.
what is your thoughts on kits like the Ender 3 NG? your kit seemed to replace almost the entire frame, vs the Ender 3 NG which uses almost the entire frame.
Ok, now I want to see a Ender 3 conversion to a Delta kinematic :D

You are a God when it comes to all the multidisciplinary aspects of this hobby. You should start your own company that uses corexy and targets the price point between 500 to 700usd. Not a speed demon ratrig but something that can do 300mms at standard quality
I think that you should try to make custom 3d printer with huge bed and on a budget.
Saif Alshamsi better to build printer with changing beds (eg 2 beds sizes 200-200 and 350-350) I have tested if to install in ender 3 on the bed drive Moyer 48 size you can achieve speed up to 120mm per second!! So what is the need in corexy??
Yup I did a CR 10 conversion to 1000mm z and x not as easy as it sounds but it's all possible just need to beef things up.
That bed transition...nice
Thank you for taking the time in appreciating our work. :)
Oh, Michael, it was very satisfying to watch this build, I like it very much, because of the efforts that were put into this project!
HI Zachary! Michael did do a fantastic review on the kit! It wasn't an easy kit to design but we're thankful for the feedback. Replacement parts are already on the way to Michael and they should solve the under extrusion issues
KAY3D Labs I love it I always like these kind of videos. Over the years I learned a lot about 3D printing and I learn and see every time new things to make beautiful upgrades. Maybe also for my channel as well.
Baffles me a bit why they decided to use the Ender 3 as a base for a CoreXY, the Ender 5 would have made much more sense.
Would it really? That would only save you a portion of the X motor weight, and that's already smaller and lighter than the Y motor, which is upsized specifically to handle the load. With CoreXY you still have that larger load for Y movements, but both X and Y motors must handle it.
When comparing benchy models most people always pass over 2 of the important parts that show a lot. The writing on the bottom and the back tell a lot about a print also.
How does this look to you?

The phrase "Lipstick on a Pig" comes to mind. Love the video but I would never buy one of these. :)
"Lipstick on a Pig" - couldn't say any better 🤣🤣🤣👍👍👍
Robert Mech what would you buy?
@@____________________________.x I'm more of the right tool for the right job. Which is why I built the LayerFused X301. I just don't see the point in taking an existing tool and turning into a completely different tool. I personally feel like most ender printers come with a payment plan. You get the base unit then spend the next year upgrading it in one way or another until you have the printer you want. I did that with my ender myself and felt like once I was done I spent far more in upgrades than I did just buying the better printer from the start. Just my opinion.
@@QuantumRob-yt The whole point is the knowledge you gain and some people like tinkering. A hobby in general which this is not compatible with pinching pennies.
@@ljohnson9440 its a piece of shit. people need to realize for some people the hobby is fucking with the machine for others the hobby is actually the printed objects. tinkerers dont excuse a piss poor product.
This kit looks like it would be fun. Maybe slap a bondtech extruder on it too
the kit costs almost as much, as 2 ender 3's just to "upgrade" a allready well performing printer. it doesnt even increase buildspace. why would people buy something like this?!
I agree totally. The Ender 5 is cheaper than this kit.
I can't see this kit doing very well.
gamerpaddy exactly i would buy more 2 units of ender 3 than this upgrade kit!!
shhh, let him get sponsor money
print speed
@@nihilisticmanit's not printing that fast and it's underextruding like crazy. trash.
Man, I feel bad for the people involved that feel that this is a commercial opportunity. While I'm sure they will sell a few units, I very much doubt the majority would pull the trigger on something like this. The Ender in itself is a 'hobbyist' printer, and largely purchased because people who want to buy it, want a cheap, decent, 3D printer. Not the mention the upgrade path involved, you would think they would at least provide some of the roller/pully components assembled. I just can't imagine who thought it was a good idea to spend 1-2 years developing this idea as a product, even just writing that ~260 page manual (lol)! With the Ender 6 (Enders new Core XY printer), hitting Kickstarter later this month --- ouch!
Don't feel bad for us mate. Every business starts from somewhere, just like yours. Some have a great start; some less than ideal. I cannot comment how much has pulled the trigger but we do have a backlog of orders making us ramp up manufacturing. This review has provided us with countless opportunities to improve; including making direct drive options available, printable cases available and other things. It has made us realise the loop holes of QC within the warehouse sorting area.
As for the manual; it was deliberate. Surely, you can leave out the pictures and details and come complete with 2 pages, front and back. Surely you could; we've seen it like creality printers and so on and so fourth. But the manual includes the nitty gritty details including eccentric nuts, how to tighten them, why tighten them, a video link to watch if you don't like etc. In a CoreXY setup, you cannot just route a belt from A to B and use an idler bearing to tighten the belt. Every bearing and idler is stacked with appropriate spec'ed washer. Without a proper manual with details; a coreXY pulley system can be catastrophic.
We studied the comments, the questions that people ask on common ender 3 groups on facbeook and realised repeated questions. All day everyday and that's when we decided to include this super detailed manual. While others may find it (lol!) like you did, we're sure others who appreciate details would appreciate the manual.
I don't know if Creality has the same type of support; But I know we do. Maybe the Ender 6 is better; maybe our coreXY system is more sound; who knows?
But I know that we don't need everyone to pull the trigger; just a small community that knows what they're doing and what they're getting into. CoreXY is a very, very intricate and complex system. A system that cannot be summed up in 19 minutes (like what Michael mentioned). It takes real details and real hours to assemble calibrate and print.
This comment is getting a little too long but I just want to let you know that I appreciate your feedback :) Thanks bud.
I was waiting for this thank you
sorry you had to see underextrusions. Hopefully the replacement parts will reach Michael soon enough and he can help do a re-test as the underextrusion issues should not happen
Damn that looks pretty great. Apart from the funky bowden path that seems to be fixable, I'm sure you could get much higher print speeds and better quality over stock easily with this kit.
Hi Mavamaarten! Indeed, the extrusions were sent wrongly. A little shy of 80mm. This made the bowden tube really compressed and the other things stick out. Hopefully Michael receives our replacements soon (we already shipped out) and can do more testings as under-extrusion should really not happen at all.
in the comment everyone trying to point out the lack of practicality, but the thing is these are really a toy and a hobby in part or in whole, and upgrades like these are things people do because they want to, not because they need to
Interesting build!
Nice. But for less of the price of this expansion kit you get a complete CoreXY printer new. Like the Two Trees Sapphire Pro. Or cartesian direct extruders with auto bed leveling. And those already come with silent stepper drivers.
Why would I pay 300usd for the conversion when I can buy an ender 5 cube ?
Pretty sure this company died. Lol their website redirects to some kind of car dealership now.
interesting to see how the ender-5 corexy kit will be when available
they had a CoreXY- the Ender 4 it failed , though not sure why, it didn't look bad as a kit from what I saw, never got my hands on one thou
@@Thomllama The ender 4 was h-bot. The new ender 6 looks like its going to be core xy.
On ender 5 all they need to do is to change the cartridges position ;))
@@depreciated incorrect, the ender 4 was a true CoreXY. The Ender 5 is an Hbot, the X motor is moved back and forth by the Y gantry. Stationary motors and The belt path is what makes a CoreXY, which it had. Take a look...creality.com/creality-ender-4-3d-printer-p00245p1.html
@@mitofun6967 Did you read out minds? :p
Nice review! I wanted an Ender 2 because of its small footpirint, but Creality stoped selling them. So I thought of converting an (broken) Ender 3 to an Ender 2. Would be a nice project!
It’s back!
What an exercise in futility. There is no reason to do this at their price.
I'm glad i wasn't the only one thinking this.
Agreed. If it came with dual extruder, at least there's some benefit over stock. But this kit is just stock function, no benefit at all. I bought BIBO2, does pretty much what this kit does + dual extruder + enclosed frame + laser etch for much cheaper when you consider your time.
Ender 3 is defo a gateway to the addicting and yet fun drug that is printing got a ender 3 mid of last year and for Christmas i just got a ender 6 core xy and dam is it fun now looking at a voron 2.4 for my end goal of a tinkering printer and maybe a Ender 5 plus just for my BIG things
Interesting upgrade
Thanks for sharing👍😀
1:00 it's about a total conversion shouldn't it be longer and in depth?
I am sure this has been asked, but what about direct drive on the extruder?
Well seeing that the company folded. Is there a way tou could share the info on this?
I have a CR10 I would like to do, and the info should be a good start.
it has a proper instruction manual
We have a local 3d printer(s) with a slightly less volume (probably) but for nearly the same price (of Ender 3 + Kay3D kit) you get a fully working 3d "box" printer with really good characteristics.
The main problem that I see here is that you need to make a conversion by yourself! It's a lot of work (for the most of users) so the price of the kit seems to be about 40-50% higher than it should be. Of course it's my subjective opinion and I can be wrong.
Bought one! Excited to print with it.
I've wanted to try a coreXY for some time due to the claimed speeds attainable, not sure this is the one though. Seems a bit steep for the result. I wish the company well though.
If you’re comfortable building your own, go with a Fusebox2r. 250mm/s speeds provided your extruder can keep up!!
Looks so satisfying to assemble this, assuming the release parts are properly sized and everything lines up. That bowden tube is painful to look at.
Looks like a well thought kit, minor issues as you stated. I do like all the aluminum brackets vs using acrylic ( they are aluminum, correct? ) My question is that after you correct the under extrusion issue , re-routing the bowden , how does it compare to the ender 5 with speed vs quality.
Hi @mark! If you don't mind, I'll like to explain that. The under extrusion was because the Z height extrusions were a little shy of 80mm. Therefore, bowden tube was compresssed, z rods and linear rods were also protruding. Replacements are already on the way and we're confident that, that should solve the under extrusion issues.
Also, the brackets are indeed aluminium. Thick, reinformeced non-3mm brackets that are extra-heavy duty.
Once can expect speed increases and stepping accuracy since hotend movements are controlled by 2 stepper drivers instead of 1. Hopefully Michael can give you a reply as well! Let me know if you need help with any other questions! :)
@@kay3dlabs668 Thanks for the response. Looking forward to see this tuned up and flying.
@@markferrick10 We sincerely hope so too!
Thanks, interesting. Cheers!
I want to see this with the ender extender kit
Oh yes it looks the same as original! What? It looks like an another printer! Is this printer over - open source? So massive!
Hey Micheal ,BIGU have put out the SKR mini e3 V2.0 with easy sendorless homing , dual z support and thermiator ahprtage protection circuit , can you do a video going over and setting up the board and verifying the thermistor protection circuit?
If it added a direct drive or at least move to lineral rails I would be tempted but it would need these to be added for me to spend 300+ for this addon
I have a Ender 5 Plus and the kit for it is less expensive. It seems to make a lot more sense for a 5 which is already a box frame without the sliding bed. The question is how much faster can I print with the conversion?
I really wish I could still get this
please please cover the voron conversion for all the same reasons you covered this one
I just went to buy one of these kits... they are in Singapore, and they wanted to sting me for $129 for shipping to Australia! AND no mention if the prices are in AU$ or US$? Still, your channel is my go to for all things 3d printing.
John, the prices are in USD. Let me know if you need further assistance. You can also write to us via email if you like
John it's a pretty big, heavy package. Shipping to Aus unfortunately often makes things much more expensive for us down under.
Michael, do you still have the manual and STL assemble gauge? I can't find anything online. Kicking myself for starting the build 3 years late. Alvin isn't replying to FB messages unfortunately. Thank you @@TeachingTech
is it printing so beautiful enough to covert with such a very complicated parts and assembly?....how many percent improvement?
The conversion kit hasn't been in stock for at least 2 years.
might want to update the link. its either not working or redirecting to somewhere that really isnt safe
I’ve been pleased with my CR10-S, for about the same $$. The print head or hot end moves along the X-axis just as much as it does when Z is 200mm. The “wobble”, seems to me, comes from the fact the Y-axis or bed is moving the tall print. I would think tuning the jerk, or running with S-curve moves would be about perfect w/ a Cartesian printer. You are adding complexity when it isn’t needed. In my never to be humbled opinion.
So for the price of an Ender 3 with the conversion kit you can also buy a Seckit Go CoreXY. I honestly can not see why this Ender 3 setup is worth it.
I think it's for the people that bought an Ender 3 and then realized what there was to gain in having a core XY printer.
@@basementdwellR Wouldn't it be MUCH easier, cheaper and just generally nicer to sell the Ender 3 for 50,- or some low amount just to get rid of it and then buy a brand new CoreXY printer for less money than this entire kit costs anyway, spend the savings on some nice extra filament to play with a brand new and better printer?...
@@someguy4915 In short no, no it wouldn't. There is not one single proper functioning CoreXY that's worth it's money under €600 which is the lowest number I can build one (that is worth building) from scratch for. There are numerous viable builds out there (ratrig, BLV mgn, V-King, Hypercube Evolution and the list goes on) , but the usual supsects like Creality and Twotrees and what have you cannot supply you with one that's cheaper and does not require a whole bunch more money and work thrown at it. I mean you might as well just stick to an Ender 3 as then.
I don't know how good this is either. This is not for me - I know who it's for though. It is a niche market as judging from the comments it's like 80% "ppffft why the hell do I need to pay $300 for this". CoreXY is the most robust motion system with the best possible POTENTIAL to produce high speed and high quality prints. If you've sank a bunch of money into your Ender 3 and realize its limitations, getting a functioning CoreXY out of it for €300 is a pretty good deal imho. This is not what I'd get though as it's too much of a compromise. I want a 3 motor Z at least for real proper mechanical bed levelling, I want a silent steppers and hiwin type linear rails. I want all the jazz. I also want a bed that's powered from 240V from the wall soket and suspended on a kinematic constraint system to be exact yet allow for expansion from heat without affecting Z whatsoever.
@@basementdwellR you sir, speak eloquently. Because we've studied what tronxy offers (which has been mentioned serveral times here), and the printed parts corexy machines, we went with laser cut metal plates and CNC parts to improve printing reliability. Thank you for believing that €300 is a pretty good deal. It's just a little disappointing people pit one product against another without consideration on the material used on parts, support available etc. We really appreciate your thoughts and comments on these. really.
Was this kit developed before Ender 5 was released?
his website is down! do you have an updated link?
One little comment: I'd unbox the kit and label those pieces first, in case something is missing. Not much point disassembling the old printer first if you can't complete the process of building the new one.
Who needs this for this price...
Do you happen to have the manual? I am getting around to building mine but the manual is no longer online. Thank you
Spiffy kit, though "conversion" is a bit of an understatement. One thing I noticed is that the Z rails and screws seem a bit long. I don't see any logic in making them longer than the Z height of the frame.
There was a section on that near the end. I have a development version, the z extrusions are not long enough but the correct ones are in the mail.
Anyone else annoyed that you loose a bit of the XY print volume? But that 400mm Y is crazy. I think this kit would be worth it if they were able to keep all the motion hardware inside the frame to allow for an easy enclosure setup while keeping electronics outside and perhaps offering a kit upgrade option for walls or just specs to source your own. Also I would pay more for a linear rails option.
Wouldn't the under extrusion be quickly fixed with esteps adjustment? Seems like that should have been the first fix after the benchy... or is it wrong to think esteps would fix the under extrusion?
It depends on the cause of the underextrusion. The problem here is that the routing of the ptfe tube seems to cause a sort of "snagging" issue, which wouldn't be consistent
You might wanna start your video with what does a core xy printer do
WOW, for that price you can buy a complete corexy.... I have 4 printers, the STOCK ender 3 pro (with capricorn and better springs) is literally one of the best printers you can buy.... But for $600 (or even another $400?!?!) you can but some pretty nice corexy printers.
Conflicted grate video as usual but seems to me a product no one was asking for especially at a price you can buy a real core XY ? Plus the fact you lose build plate area to me that's more important then gaining some extra height. For me your other ender3 extender video product is a better option. How about you do a DIY ender3 video where you get some 2040 extrusion new longer Z screw, cut it your self or precut and extend the Z axis it's a far cheaper option then all these and its easy to extend or make new leads for the X gantry?
Interesting. Could you fit it with a tool changer?
That's a great question! We're in the works of retrofitting one of the existing tool changing solutions in the market into our corexy conversion kits on the ender 3 & 5 series (including 5 plus). On the E3 space is a little tight so maybe the number of tools will max out at 2. One of the problems with tool changing is that you usually need more Y space at the rear also. However, there is not ETA of the timeline available but we usually update from time to time on our progress! :)
It seems like Bowden tubes drag on the filament a bit and increase the load on the stepper. The alternative is to put the feed stepper on the moving parts, but that increases the mass of the gantry, reducing acceleration. Is it possible to "lube up" a Bowden tube somehow to reduce resistance without getting gunk on your hot end, and without contaminating the filament? If that's not practical, can you upgrade the stepper on the feeder and get more oomph out of it and increase extrusion force, increasing extrusion rate? That might require an upgraded hot end that can melt more material per second, but might be worth it. What do you think?
Next up: upgrade your Ender 3 to an STL or powder printer :D
(Its on sale, just 3999$ today!)
Okay so wait. Why would I buy a kit that costs literally the same as a core XY printer?
That explains why it looks like they're out of business.
YOUR A GENIUS!
Did you run a skew test in the X and Y as this can occur if the dimensions are not perfectly aligned on a coreXY, or the belts are over tightened, the way to see if you have a skewing issue, is to look at the prints of holes, if they are relatively round your O.K. but if they are oval you have a skew issue in your gantry
you might want to remove the link to their site. it is now someone trying to get you to install something on your browser.
You are creating great content to 3d community.
Please use grey filament when printing test cubes or benches. There is a reason that most of the primers are in grey, they highlight imperfections.
This lime green bench is worthless if we can not see anything.
I will wait for Creality Ender 6 core XY
Ender 6 available soon... and it is a Core XY. Does it mean the game is over for Kay3D?

for the same price you get massive print volume, bl-touch, silent board and touch screen. slap a capricorn and a decent extruder and you get an astonishing printer.
8SharkTV Moshe ender5 isn't corexy
Seems kinda pointless to me. If you want a core xy printer for whatever reason, buy one that's actually designed for it.
Did you miss the start of the video? This is more for someone who has an ender 3 cause that was his beginner printer and now would like a core xy. If someone only want one printer this is a cool option. Also saves one from having to go through the process of selling the old printer and picking a completly new one.
@@lukas1672 I have that Ender 3, like so many people and while I have done a few upgrades (most recent one I did was direct drive upgrade for instance) this kit makes no sense and solves no issue you'd really have... This kit does not increase build area which is a major disappointment.
I'd much rather sell my Ender 3 to some kid for a low price and then buy a brand new printer with larger surface and Corexy design for a lower price than this entire kit, the money I would then save can go into filament...
So relatively complicated and more expensive kit or brand new 'adventure' with a new printer which is cheaper anyway while making some kid happy with your old Ender 3, easy choice really.
I applaud them for trying to make the Ender 3 corexy, I just really don't see why anyone would spend this much for such an upgrade on the Ender 3, this also seriously limits any options for increasing build area as you'd basically need to replace nearly all the parts of this kit again...
@@lukas1672 Still doesn't make sense to me. In that case, just sell the printer and get a different one.
This is more "build a CoreXY printer with bits from an Ender 3".
Which is pretty much what I did by buying 2 Ender 3 Pros to start from and not even assembling the second because buying the components you can use from an Ender 3 in a build cost quite a bit more separately than the 170€ I paid for my Ender 3 Pros.
what is your thoughts on kits like the Ender 3 NG? your kit seemed to replace almost the entire frame, vs the Ender 3 NG which uses almost the entire frame.
Ender 3 V2 compatibility...?
Does it works with ender 3 v2?
