Ohhh, you fixed left audio channel only. Thank you!

[@conorstewart2214]

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.

[@fladder1]

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.

[@MorlockEngineering]

Okay, I will make a video on this.

[@MarinusMakesStuff]

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.

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.

[@doug.ritson]

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 KZbin 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.

[@jeremyocassan]

[@eatonasher3398]

This is incredible!! Very well done; I will definitely be buying your next version!!!

[@blazehenot2536]

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!!!

[@MikeKasprzak]

Lovely. I've enjoyed the various clips from 3D printer KZbinrs. This is the sort of thing I would love in my workshop (*cough* garage). Will be continuing to keep an eye out.

[@MorlockEngineering]

Thank you!

[@Jon.S]

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.

[@WeberMachineWorks]

well said Jon.

gods work. you are doing gods work. its like a stopgap until real 3d metal printing gets to the consumer level

[@NigelTolley]

Consumer 3d printing, especially with metal (if it ever even happens) will never be as accurate as these machines can be.

[@alexross26]

@@NigelTolley why. rocket engines and jet turbines are 3d printed, I think those industries require accuracy

[@NigelTolley]

@@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!

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 . . .

Amazing machine. Wish you the best

[@trivalentclan-mizar9591]

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.

[@ethanmiller5487]

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]

>4 machines That is not a lot at all.

[@ethanmiller5487]

@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.

[@MorlockEngineering]

That is still only a few ten of thousands machines. There are millions of mills, lathes, and printers.

[@ethanmiller5487]

@MorlockEngineering Did you state that EDM is more rare then those other machines or rare in general?

[@xorfive]

[@bacawaka2813]

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.

[@plasmashears]

That's what I was thinking too. Not super common, but definitely not what I would consider "rare".

[@Properuppercut]

I worked in a shop with 16 wires for 20 years. Agreed, not super rare in the manufacturing world nowadays.

[@areyounecessary]

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.

[@Lolatronn]

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.

[@davidapp3730]

An amazing project.

[@michaelmueller9635]

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.

[@elanjacobs1]

Not with those tolerances. You want to be in the 5-10 micron range, not 50-100.

[@samrix5793]

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?

[@LeviathanPits]

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?

[@darkenblade986]

""" 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

[@martindieux]

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]

Thank you. What do you mean by industrial?

[@martindieux]

​@@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.

[@bransonlariscy4660]

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!

[@Hukkinen]

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! 😀

[@fabienl4979]

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.

[@Hukkinen]

@@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 =)

[@diditwork370]

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.

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!
