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.
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.
In two days I've seen an open-source DIY metal sintering injection molding machine, an open-source DIY high-vacuum furnace, and an open-source DIY 4-axis EDM machine. This is so insane. What a time to be a maker. You're all incredible and heroes for the open-source community.
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 TH-cam 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.
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.
10 years from now we will be making microchips at home. sometimes i think in future people will just make everything by themselves , kids talking about how their os is better , making their own chips. it will be crazy
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.
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 am a hobbyist machinist and metal worker, I have two lathes, a bridgeport mill and a surface grinder. I've wanted to buy a used wire edm machine but those available are usually ancient and non running and in need of repairs. This make be in my future, depending on the working envelop of the tool

Brilliant design. I used to operate an industrial wire EDM and plunge EDM so I know what you are talking about. Generally, these are machines that can machine metal to an accuracy of 0.01 or even 0.005mm There is a basic condition - the machine body must be temperature stable. Your idea is great- maybe we won't achieve the accuracy of an industrial machine but yes the accuracy will be higher than for example 3d printing. 👍👍👍👍👍👍👍👍👍
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!
@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.
I'm with you on this one Ethan, wire EDMs aren't "rare" or "lost" technology. They are simply more niche due to the inherent process limitations. Mills don't care about the conductance of the material and are generally capable of being precise enough for most applications. EDMs also cause a "recast layer" which is essentially a casing of re-solidified metal where it was cut which can affect part geometry and lifespan.
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.
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.
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 ❤
@@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.
@@alexross26the biggest problems are huge issues: grain structure (or lack thereof), and internal stresses. When printed parted are heat treated (for grain bond and stress relief), the parts change drastically. Metal 3d printing, currently, is about as consistent and reliable as casting.
Lovely. I've enjoyed the various clips from 3D printer TH-camrs. This is the sort of thing I would love in my workshop (*cough* garage). Will be continuing to keep an eye out.
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!!!
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 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.
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.
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?
Yeah these things are not rare, that's complete bs. this is a cool project but I've seen 3 different ones in the last 6 months on facebook marketplace alone in my area, and I'm not even in a super industrial city like chicago
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 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.
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.
You need a way to keep the tank and exposed components clean. The debris from edm usuallly requires a cleaner like lime-a-way so make sure the materials you use can resist acids.
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!
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 . . .
I'm not seeing any examples of 4 axis wire edm. The tool shop I used to work at had a Mitsubishi 4 axis wire edm that we were cutting actual 4 axis parts. This machine cost about 250,000 dollars in 1995. We also utilized some elaborate post process programming to generate the math to move all 4 axis in unison. Our 4 axis parts consisted of tapered cuts through s7 steel going through 1 inch thick to 4 inch thick parts. Another example was a transition of a triangular shape hole on one side of the part with a circular shape hole on the other side. Amazing that the process could create all the geometry from one side to the other. Like I said, this isn't 4 axis. I do congratulate on creating a 2 axis machine.
Hey we have the exact same watch! great nerds think alike. :D looking forward to placing my order. this machine is exactly what I have been dreaming of for years. Thank you for your efforts.
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
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 =)
This work is so amazing, thank you so much for your effort. I can finally have a proper cutting machine in my apartment, without the misses complaining about noise, haha
I have to say that this project is really impressive. I come from a CNC Kitchen video and this catched my eye. Got to do my own research to get here. Let's boost the algorithm. This is real work of art and engineering combined. I work in plastic injection moulding and I have to design the electrodes, many of which are wire edm cut. I would love to buy one, or maybe wait for the industrial scale one. I would also love a video of the 3D assembly. This project has future.
@@MorlockEngineering I mean no disrespect but, like with 3D printers, it takes a period of time where a product becomes better in the way that it's worth buying for bussinesses. For a guy in his garage, this is epic. But for a small/medium bussiness the risk is too high. They would probably spend more on something that has more experience/background.
I'm super thrilled about this. However, according to Teaching Tech and others, the big holdup frequently isn't the hardware, it's the software. How do we generate toolpaths and so on that work on this?
I own a desktop CNC and it's a pain in the ass in so many ways that this solves! Including metal particulates flying everywhere, lubrication requirement, and extremely rigid chassis. And you're telling me you can cut tungsten carbide? My desktop CNC can barely cut aluminum 6061. Great work!
Nice project , just take in consideration water shall be pure and filtering is a crucial parameter on wire EDM , aluminium is easy to cut but worth to filtering
EDM's are nice, CNC machines are evil monsters. Also EDM's are going extinct. Save the EDM's. All joking aside, this a cool project! I hope it does well and has LST and continued development.
""" 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 """ - joel_mckay this comment wont be deleted
I am currently going into my senior year in a mechanical engineering degree and would love to discuss the possibility of interning. I’ve taken some introductory CAD classes and have used inventor to design parts and to create some simple assemblies. I would love to further my CAD capabilities and to work on such an interesting, innovative project. Loved the video !
For hobbyist, EDM offers the ability to cut through ANYTHING conductive. The actual accuracy isn’t the vital part, it’s the ability to cut Titanium, or whatever, moderately accurately.
love the idea and functionality. However, I buy tools to make small batch parts. I am more than a hobbiest, but less than a full blown protoype shop. I would be very interested in a fully built "kit" such as common P printers. Or better yet, a fully assembled version, like you get in the Bantam CNC machines. Either way, thanks for making this leap, and I will keep an eye out for future projects and advancements of your.
Hey I love this project and I say this from a place of good will. I think you have massively over engineered that enclosure. It doesn't need magnet snaps for the power supply etc simplicity now will save you a lot of future pain.
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
Is there a way to ‘punch’ holes completely in the interior of a part? Perhaps using the stand alone rod to make a hole then threading the wire through it? That’s perhaps the biggest drawback of wire edm compared to other methods
@marcusrauch4223 In very hard materials, it could be much easier and more precise to use a rod to create a small hole for the wire. Also, with that alternative attachment, you could produce some other geometry not possible with strictly wire edm.
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!
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..
This is amazing! Great work.
There's no words. Just a standing ovation. Great work and a great project. May the market appreciate your contribution. Unbelievable.

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!
I'm not seeing any examples of 4 axis wire edm. The tool shop I used to work at had a Mitsubishi 4 axis wire edm that we were cutting actual 4 axis parts. This machine cost about 250,000 dollars in 1995. We also utilized some elaborate post process programming to generate the math to move all 4 axis in unison. Our 4 axis parts consisted of tapered cuts through s7 steel going through 1 inch thick to 4 inch thick parts. Another example was a transition of a triangular shape hole on one side of the part with a circular shape hole on the other side. Amazing that the process could create all the geometry from one side to the other.
Like I said, this isn't 4 axis. I do congratulate on creating a 2 axis machine.
Hey we have the exact same watch! great nerds think alike. :D looking forward to placing my order. this machine is exactly what I have been dreaming of for years. Thank you for your efforts.
Can't wait for this, I'm ready to build one!
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
Pure genius. I'm a manual machinist, the only CNC machine I have ever desired is a EDM machine.
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 =)
This work is so amazing, thank you so much for your effort.
I can finally have a proper cutting machine in my apartment, without the misses complaining about noise, haha
Stunning! Been subscribed for a while and the progress is substantial. Keep up the good work!
When do you expect the 50 micron machine kit to be avaliable? Looking for 0.001" in accuracy
BRILLIANT. Easy, nobrainer subscription. I am looking forward to adding an EDfrigginM to my capabilities!
I personally dont have any uses for this, but I'm tempted to get one just to help out. This is amazing
I have to say that this project is really impressive. I come from a CNC Kitchen video and this catched my eye. Got to do my own research to get here.
Let's boost the algorithm. This is real work of art and engineering combined. I work in plastic injection moulding and I have to design the electrodes, many of which are wire edm cut.
I would love to buy one, or maybe wait for the industrial scale one. I would also love a video of the 3D assembly.
This project has future.
Thank you. What do you mean by industrial?
@@MorlockEngineering I mean no disrespect but, like with 3D printers, it takes a period of time where a product becomes better in the way that it's worth buying for bussinesses. For a guy in his garage, this is epic. But for a small/medium bussiness the risk is too high. They would probably spend more on something that has more experience/background.
I'm super thrilled about this. However, according to Teaching Tech and others, the big holdup frequently isn't the hardware, it's the software. How do we generate toolpaths and so on that work on this?
We have our own 4-axis CAM suite written in C & Vue.
@@MorlockEngineering is that going to come with the tool or is it for internal use only?
I own a desktop CNC and it's a pain in the ass in so many ways that this solves! Including metal particulates flying everywhere, lubrication requirement, and extremely rigid chassis. And you're telling me you can cut tungsten carbide? My desktop CNC can barely cut aluminum 6061. Great work!
Nice project , just take in consideration water shall be pure and filtering is a crucial parameter on wire EDM , aluminium is easy to cut but worth to filtering
We generally run 10 micron filters on our 100 PSI flushing pump.
@@MorlockEngineering does the Kit Include the pump?
I appreciate good engineering. This is good engineering.
Brilliant work! Just amazing! 👏👏👏
I like where this is going,great accomplishment. I need a source for Supertec w-edm parts for a 90’s built unit
EDM's are nice, CNC machines are evil monsters. Also EDM's are going extinct. Save the EDM's.
All joking aside, this a cool project! I hope it does well and has LST and continued development.

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

I am currently going into my senior year in a mechanical engineering degree and would love to discuss the possibility of interning. I’ve taken some introductory CAD classes and have used inventor to design parts and to create some simple assemblies. I would love to further my CAD capabilities and to work on such an interesting, innovative project. Loved the video !
exciting, always wanted to try one out, so looking forward to getting one. great video too.
This is awesome! Have you tried cutting tungsten carbide?
For hobbyist, EDM offers the ability to cut through ANYTHING conductive.
The actual accuracy isn’t the vital part, it’s the ability to cut Titanium, or whatever, moderately accurately.
Making an edit, because I don't want to take away any business from this interesting project. I'm rooting for your success.
WOW This is the first time I have seen this it is amazing!
love the idea and functionality. However, I buy tools to make small batch parts. I am more than a hobbiest, but less than a full blown protoype shop.
I would be very interested in a fully built "kit" such as common P printers. Or better yet, a fully assembled version, like you get in the Bantam CNC machines.
Either way, thanks for making this leap, and I will keep an eye out for future projects and advancements of your.
Awesome. Is it possible to recover electrode material from the water bath?
This is simply amazing to see!
Hey I love this project and I say this from a place of good will. I think you have massively over engineered that enclosure. It doesn't need magnet snaps for the power supply etc simplicity now will save you a lot of future pain.
Beautiful work! I'm impressed!
This is awesome! Looks less difficult to build than the Voron 2.4 r2 I'm currently building.
If this becomes widespread as 3d printers it's really going to shake things up. Imagine the printer manufacturers start to get in on this.
Brilliant thinking. Creatvie mind is millions times better then gold.
This is amazing, please tell me you are working on larger sizes
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
Is there a way to ‘punch’ holes completely in the interior of a part? Perhaps using the stand alone rod to make a hole then threading the wire through it? That’s perhaps the biggest drawback of wire edm compared to other methods
Legendary work. Well done.
Ohhh this is so cool. I would definitely buy one!
RackRobotics, whe're you? Please, come to life!
Will it be able to have a tool swap head to use a brass rod to boar a hole to start a wire cut inside a shape?
why not pre drill one?
@marcusrauch4223 In very hard materials, it could be much easier and more precise to use a rod to create a small hole for the wire. Also, with that alternative attachment, you could produce some other geometry not possible with strictly wire edm.
Yes. That is a future possibility. We have done it before.
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!
can't wait to order powercore v2
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..
This is way cool!
Great Work Rack Robo!
Any concerns with patents? Incredible work, cannot wait to see this evolve.
