This is amazing! Great work.
Ohhh, you fixed left audio channel only. Thank you!
I was wondering if I was going crazy and that I had seen it before or if this was someone stealing someone else’s video, but it makes more sense if he just reuploaded with the audio fixed.
Seriously, this is the most excited I've been for the past decade. I'm definitely going to follow this and most probably buy one of these kits sometime down the line, so get ready to have them shipped to Europe.
Would really love to see the actual work flow from design to cutting. Awesome project, as soon as it comes available in Europe I'll order one.
Okay, I will make a video on this.
Hey awesome, I'm definitely going to buy this. One tip, I think it would be really interesting to make some type of upgrade route where the EDM machine can cut its own replacement parts out of aluminium to make it stiffer. So it would be great if that is kept in mind when designing the 3D printed parts. Beyond that, awesome design! I can see a lot of love went into the design of this machine.
Recursive manufacturing. Beautiful!
@@markTheWoodlands Let's go on a recursion excursion safari!
I do not see myself owning one of these, but will be watching your journey - easy sub to make. When shop/homemade CNC machines were first being introduced on RUclips I predicted we were at the beginning of a new industrial revolution. I believed the CNC would drive a router, and with some modifications a laser. I'll now add and EDM to the list. The incredible power for inventors/makers with these affordable machines tinkering in a garage or basement will really advance society in both good and bad ways. Thank you for sharing. Great little machine.
Why are the bad ways? Gun inventors?
Just found your channel and project for the first time. 100% saving up for this. I can already think of a few projects that my makerspace could use this on. Thank you for putting in all this work ❤
I'll wait for better tolerances. Gratulations gor your achievements so far! Super impressive
I feel that software experience is going to be key, if you can get the user experience as noob friendly and approachable as modern 3D printing there’s a huge market of people who’d love this. If the process to get a part machining is esoteric and relies on the user being a CAM/klipper expert then it’s going to be a tough ask for most hobbyists.
well said Jon.
Commenting to boost the trip vid
I'm very impressed with this project, both in innovation and straightforward, elegant, engineering.
Thank you!
Its going to be wild to see the kind of projects and products that this enables. Your existing non wire EDM machine already opened the door to precision manufactured 2d and stamped parts. adding a whole extra dimension with the capacity for precision rotary manufacturing as well is even more mind blowing! Best of luck in your future endeavors I can hardly wait!!!
Stunning! Been subscribed for a while and the progress is substantial. Keep up the good work!
Lovely. I've enjoyed the various clips from 3D printer RUclipsrs. This is the sort of thing I would love in my workshop (*cough* garage). Will be continuing to keep an eye out.
gods work. you are doing gods work. its like a stopgap until real 3d metal printing gets to the consumer level
Consumer 3d printing, especially with metal (if it ever even happens) will never be as accurate as these machines can be.
@@NigelTolley why. rocket engines and jet turbines are 3d printed, I think those industries require accuracy
@@alexross26 Rocket engines are printed from massive rolls of welding wire by robot arms and turntables. It's very neat - I've seen it happening - but the accuracy is in the millimetre range. The nozzle is metres across. You couldn't fit the machine in your house, even if you took the furniture out, and the 3 phase requirements are rather high. Oh, and it is £millions too. Jet turbines are done via a rather more accurate process, something like direct laser sintering of metal powder heated to near melting point under an inert gas. The risk of an inert gas killing you and your entire family in your sleep is likely too high for most, as well as, again, the power requirements and the costs that start from £200k. Maybe as low as £60k for the very lowest kit.
Having said that, there is a nylon 3d SLS/DLS printer coming out soon, running about £2k, dropping the price from the £16k bottom end of the market currently. Micronics. Look them up!
@@NigelTolley I went to a conference 30 years ago held by Apple where they explained why computers would never get any faster. Plenty of surprises to come with this technology.
Rare? My father bought a used one in 1980 for his Tool & Die shop, my older bought two more in later years. Many other shops had newer Wire EDM machines. I learned raw G code programming using a teletype for our first wire EDM machine. One of my coworkers at a research laboratory out sourced his parts to machine shops using wire EDM machines.
Sounds like you’re rare too:)
@@dlynch8668 eh he's pretty much right though they aren't as rare as he's saying. maybe 4 axis ones but thats a guess
Yes rare, as in most people have heard of a mill, very few people have heard of wire edm.
Those few ppl are idiots and morons but what else is new🎉
Such a clean design! Excited about printing the Betta Wire as soon as the files are available.
Congratulations. I hope you sell a million of these!
I hope so too!
Beautiful work! I'm impressed!
This is way cool!
Great Work Rack Robo!
I keep watching this in an anxious amazement. I've had to have shared this like 20 times.
Glad you enjoy it!
Looks great. I'd use button head socket caps where possible so all forces are basically compressive. The countersunk can flare and crack plastic if overtightened, button head are more forgiving.
I need one of these! I have been thinking about building one for ages. This project may be it. Can't wait!
This is actually crazy. Awesome.
Amazing to see this! awesome work
That's incredible. Fantastic work.
Damn, one video and I subscribed. Thats a record. I want to watch the progress of this device and your new company. Congrats!
Yes exactly my thought, I even subscribed after a few minutes into the video. Well made video, incredible to have access to desktop wire EDM machine (with a 400$ power stystem). Like he said, when I watched the prices back then for the power supply it was really 2-3K. So I'm looking forward to seeing the next version of this machine with great care.
BRILLIANT. Easy, nobrainer subscription. I am looking forward to adding an EDfrigginM to my capabilities!
hell of a power supply there fella.
beautiful.
exciting, always wanted to try one out, so looking forward to getting one. great video too.
Amazing machine. Wish you the best
So cool. I think a sinker version would be cool too.
I had no idea wire edm was so rare! Thankfully I work in a shop with 5 of them.
That's what I was thinking too. Not super common, but definitely not what I would consider "rare".
I worked in a shop with 16 wires for 20 years. Agreed, not super rare in the manufacturing world nowadays.
Thought the same, worked in a machine shop and we did occasionally outsource EDM work, and I can think of 4-5 shops that were within a 30 minute drive of us. Major metro city, so obviously not the norm, but still.
That said, this is still a fantastic idea, especially for those who live in apartments and the sort. Being able to manufacture metal parts in my room without bothering the neighbors is fantastic.
They're not rare 😅
Same
This is simply amazing to see!
My lord this a revolutionary, incredible work
Indeed. This idea has the capacity to change the hardware world.
Very interesting, i didn't see the Kickstarter but interested when it comes out. How often does the wire break mid cut and how easy is it to thread, is there a way it can auto thread?
Yes, very good, like a lot. Sadly poor and luckily european, so eagerly standing by and thrilled for the things to come. :D
We will get to you soon.
@@MorlockEngineering Kisses.
Maybe EDM is rare where you are but in MN, with all the manufacturing, there are tons of them. It's normal for die shop to have 4-5 wires and that many sinkers. Injection mold shops probably have more of both. A lot of shops, like mine, even have EDM drills. I LOVE this project! I will be buying one for my home shop!
>4 machines
That is not a lot at all.
@MorlockEngineering That's just one shop. There are hundreds (if not thousands) of mold and die shops in the US. Each has at least that many machines... that's a lot of machies. The bigger universities have machine shops as well and they definitely have wire machines.
That is still only a few ten of thousands machines. There are millions of mills, lathes, and printers.
@MorlockEngineering Did you state that EDM is more rare then those other machines or rare in general?
WOW This is the first time I have seen this it is amazing!
Can't wait for this, I'm ready to build one!
This is so cool!!!!
Nice work! Following your work! And subscribed.
Congrats on developing a game-changing machine! When are you guys looking to expand the team 👀? I’d love to contribute to a technology that will change manufacturing as we know it!
This is incredible
On my infinite bucket-list... but a hat-tip to you for doing a decent job! Thank you.
You are welcome. Thank you for buying me lunch!
Ohhh, very good, I worked doing mechanical projects and drawings for the first wire edm made in Brazil, it was long time ago, 1980. The electronics was made for a friend, he is electrical engineer, i belive this machine is working 'till now, was usede a Diadur CNC 2 axis only . . .
Very interesting project
Its beautiful
Great work!
This is awesome! Have you tried cutting tungsten carbide?
I personally dont have any uses for this, but I'm tempted to get one just to help out. This is amazing
I'd want a more 2d axis version, designed specifically for sheet metal. From watching this video (no further knowledge) that would be the best use case for this type of machine.
Nice job!
Ohhh this is so cool. I would definitely buy one!
I'd love to build one!
This is brilliant! Is the power core sold separately from the EDM Machine or does it come with it?
This is awesome. I'll be looking into this and following along. A wire chopper is a very good idea. I watched a guy drop a used wire spool and end up needing is calf muscle put back together.
An amazing project.
Awesome! I created "GatorCAM for cnc" with slow feed speed capabilities to allow for EDM!
You may really like it!
Great work
Looks really well designed.
Thank you.
Imagine, you could essentially print a planetary gear box with it.
Maybe it wouldn't be efficient and time-consuming, maybe some flaws. But as a demonstration in practice, it would be very impressive.
Not with those tolerances. You want to be in the 5-10 micron range, not 50-100.
With that Fith axis you could in theory cheaply make a lead screw for a 3d print plastic recycling machine if the tolerances are tightened up more. Then all you would need is a grinding machine which all you would need to do is cut out some gears and make a sturdy attachment for them.
I love it. Very cool 👍
This is awesome! Looks less difficult to build than the Voron 2.4 r2 I'm currently building.
Awesome. Is it possible to recover electrode material from the water bath?
can't wait to order powercore v2
This is amazing, please tell me you are working on larger sizes
This is Stanley Meyer level knowledge
This is awsome, ive looked many times for a mini EDM for my hobby shop. When will it be ready for purchase and how would I go about ordering one? Is there anyway to place a pre order to ensure I can get when as soon as they are released? What the limitations are as far as material thickness and material type such as hardened tool steel, Can you use the wire as an edge finder to locate your part, or find the center of a hole before you start cutting? Great Job!
blown away with the sexy design of this.
This is gonna change the 3d2a space forever

Hi, this looks like a very fun project, and here are a few tips: =3
* Add a GFI on the power input, and ground your frame properly... or UL will get cranky
* Add manual magnetic interlock + emergency stop (i.e. if the power pops back on it doesn't cause injury)
* Add a DPDT contactor to be able to invert the work-piece and probe polarity (this is used with a sacrificial surface to resharpen sinker probes)
* Klipper is not likely going to work they way you need... because EDM is a closed-loop _adaptive_ non-contact milling process (i.e. the motion may back out of a cut to re-set the ark distance, adjust feed rates to prevent excessive surface pocking from over-current, and drop voltage to minimum to localize the cutting line.) LinuxCNC/EMC people have done numerous custom machines over the years, but the kinematics require a reasonably powerful PC to do 3+ axis.
* most EDM systems I've seen use copper coated molybdenum wire
* Many papers have concluded for wire EDM it is best to run 3A to 10A , 60v to 130v, 1MHz, and 30% "on" duty cycle. (Note: the FCC EMI rules are a $1m fine, so a fish tank likely won't do...)
* most EDM have a dry touch off process, and only fill the tank with liquid just before a run
* most modern EDM out of Japan can self thread there own wire to repair breaks or do multiple islands
* bearings and ruby wire guides are standard consumable parts
* helical milling spiral-cutter flutes or threaded-holes in carbide is still done in the USA
* Contact the CAM tool box author for FreeCAD. I met him during my project days, and he is a nice community minded person.
Don't splatter the RF spectrum... I guarantee you some local radio operators will find your machine in minutes. In my country it is a $5k fine and minimum 1 year in jail.
This message will be deleted in a few days... Good luck =3

Nicely done. Let me know if you ever have a use for a coop student!
yup. I want one. subbed
This is very cool! Id love to see an applications video where you show what this can be used for.
Any future plans for a toolhead to do conventional EDM instead of just wire?
Thanks for sharing, if you make some videos telling the theory of operation of the power supply i have good expertise to suggest improvements, also I may have some tricks in my hat to lower the PCB BOM cost
Incredible
Wow , very cool machine ,impresive work, this machines ,the big ones cost a lot of money ,i think there is a market there for litle but usefull machines like this
I’ve been making EDM since sandstorm… was clearly doing it completely wrong. I am absolutely building one of these thanks you!
Pure genius. I'm a manual machinist, the only CNC machine I have ever desired is a EDM machine.
LOOOOOve your stuff !!!! hope to get one as soon as i can
Thank you!
Wow! Bringing this tech to the hobbyist is incredible. For small to mid sized workshops, do you think it's possible to scale this up? Here's the dream: being able to cut standard >12mm thick steel sheets at pace with insane tolerances (without having to fork over silly amounts of money for laser cutting equipment), and keep floor space usage minimal.
I have a couple thousand hours on professional EDM and this excites me very much.
Little tip, even if your hardware is flawless, it's all about the controller and software.
My Voron has single micron repeatability but it's useless without correct compensation.
Yes. I agree.
This, and the SLS 3d printer thats hitting the consumer market are literally game changing. At home manufacturing is finally becoming a reality.
perfect, im even still awake
I can cut and make lots of things at home with consumer 3D printers and laser engravers/cutters (Fiber & C02) but metal is not one I can really cut, expect for 0.2mm AL card.... This is an amazing development for home makers, well done!
So hyped for this can I still use my powercore v1?
Noice!
Does it have any water filtration?
Does it need it?
I’ve already got a powercore. Haven’t gotten around to installing in on my old Prusa. Interested in buying the kit without the powercore whenever you’re able to make that an option.
Might consider self sourcing the kit parts otherwise, but that’s probably more hassle than it’s worth..
When do you expect the 50 micron machine kit to be avaliable? Looking for 0.001" in accuracy
What is this Voodoo magic? I have just purchased my very own workshop and planning the machinery right now! THis is definatley going to become part of the landscape!
thanks for the audio
Let's go, this is very cool
Hello, will there be a BOM and/or videos on how to build one of these? Or will it be kept closed and you just have to buy the kit? In particular, what can I do if I already have the v1 power supply and would prefer not to re-purchase?
Just a note, we have 240 Volts rating in Sweden (Europe).
It was 220 decades ago.
Now we got 230 in practice.
Yes
Amazing! Great job! Is this noisy when cutting?
No
Amazing! Saw you guys @CNCKitchen. This as a disruption! Micro-mechanics: gears, watch parts, micro-surgery tool parts, brushless motor stators, gun parts, and injection molds etc. Open source, engineering, and product development at its best! I hope you great times! 😀
It's not a new type of machine. Watch parts are much more suitable with laser cutting and/or photoetching cutting. The wire has a diameter really not negligeable for micro parts to create. EMD wire machine can achieve incredibly tight tolerences but a micro gear or watch part, laser cutter can do sharp inside/ouside corner with not radius.
But I'm totally agreed with you, a desktop affordable wire EDM machine could me incredible, mostly the 400$ power supply. After that it's the precision of the X-Y movement of the machine, rigidity and so on that will dictate it's precision. I'm looking forward to seeing the machine and its price.
@@fabienl4979 Thanks for the detail. My bad; perhaps only clock parts, then (which actually someone mentioned) ;)
Sounds like rigidity is a simple problem. Then again, I have no idea about microscopic tolerances of a dynamic system =)
He's the Josef Prusa of wire EDM - well done
I have been trying to build one for three years with the same idea of 3Dprinted parts and China pcb/components etc but not got the electronics right. There are some other guys that make electronics they claim is pro level but it is $2000! As mechanics I found a thesis from the Netherlands, an university there, but they built it of metal parts and it was a co-operation between a mech team and a electronics team. It wasn’t open source and I couldn’t track the students. Are you aiming at making the current version open source? A side note: it is good to have a filtering system for the water and a meter for conductivity! Great project! Subbed!
