Do any one has edm (electro discharge machine) circuit to make it.please send me some detail

Google it there’s a few sites based on a book that’s out of print now. I’ll have a look later if I get time.

There were articles a few years back in Model Engineers Workshop or Model Engineer describing how to build one.

Which kind of capacitors used in edm

Hi! I realise this is a little old thread, but figured I’d show you what i found in case you haven’t already found it.

I’m starting plans to build an EDM machine.

Loads of info at

I’m looking into going with a smoothieboard for control.

I’m interested. I don’t know that I actually need EDM but that doesn’t make it seem like a less awesome project. :grin: Looking forward to hearing more.

It’s sure convenient for removing a steel tap broken off in a chunk of steel.

I’ve seen some stunningly precise edms on youtube based on BaxEDM power supplies.

Appled Science is one of the people I follow on YouTube that does lots of fantastic DIY equipment projects.


Hey all! I’m moving forward & creating my own Arc Generator and planning to control it with pulses from an Arduino DUE board. This will all go onto an X-Y control board that’s controlled with a Smoothieware based board.

If all goes well within a few months I’ll have a working prototype machine. I may sell the ARC Generator, or the curcuit board & parts list so anyone interested can create their own. Well to be accurate I’m paying an expert to design the Arc Generator circuit.

Later I may consider selling machines, but for now I’m focusing on making one machine that works. I may make a youtube series when I start building. Right now it’s in planning stage. I have about 5 pages of documentation based on what i’ve learned from 3 different youtube series. Applied Science is the first one I ever saw & he learned some of his stuff from BaxEDM.

I have lots of experience with 3d printers, aquariums, electronics & welding. So why not use all that to make a large EDM station? I built a 3d printer that has a working area up to 25X25X20 inches. I’ll probably use parts from that to make a huge EDM.

Smoothieware may need a little tweak to have a movement speed control based on the voltage at the cutting location. I’d start with a laser cutter profile and go from there since the EDM would operate very much like a laser table. Hopefully that won’t be too hard. Anyone have ideas on that? I may eventually make a new topic for that, or for this project all together. I don’t mean to steal the topic from OP here, but the ARC generator IS related to the original topic.


I suggest making a new topic (we can even move your posts to a new topic if you like), and you can even do what I did for monocle — name your project, and start posting new topics under that tag for the different parts of the project.


OK, I’ll create a new topic. Just one is all I should need I think
