Between FDM and Resin 3D printers, home desktop CNC, home desktop (but you probably want it in your garage) laser engravers and laser cutters, and now home desktop sized EDM, the barriers to entry for rather serious, professional manufacturing capacity (if low speed/volume) have become laughably small. This is wonderful for at-home makers interested in taking ideas in their head and making them into products in their hands without breaking the bank. I love seeing all these technologies progress as fast as they are.

@@rolandomartin Both of which won't find in your average home garage due to their insanely high equipment cost. Wire edm and cnc plasma are for different applications. A small DIY CNC plasma cutter build would be 2ft x 2ft, most are at least 4ft square but they can cut very fast. Wire EDM is better for small precision tasks but takes much longer. I have a good sized cnc milling machine (not a router) but I could find uses for this wire edm. I've broken plenty of tiny end mills over the years, this would solve that.

@newmonengineering 2 ай бұрын

I would say, that every technology has its place, but it depends on the job as to which one to choose. For cutting metal, a cnc can do more depth 3d stuff like blond holes and shallow pockets while maintaining the bottom for 3d parts. Laser and edm and plasma are mostly for flat sheet work to cut all the way through. So it always depends on the job. If it's small precise work with thick material edm is great. Laser is thinner mostly but faster. Plasma can do a decent thickness at a decent speed but has a huge kerf and may need cleanup after. So the choice depends on the goal of the project. I don't do anything that would benefit from edm, but I do have a cnc and laser because they best solve my projects in the shortest amount of time.

I put together an article for "Home Shop Machinist" magazine, soon to come out in the next couple months, of a EDM die sinker I made from scrape parts, made to look really nice, that anybody can build. I got delayed about October a few months ago, when I moved to my new location, and soon I will have the new shop (hopefully) at least to a 80% running status, and I can then finish the DIY wire EDM machine also made from scrape that anybody can make, for about $60 USD and the scrap used to make the unit look nice, and all source able on the shelf parts for ease of building and servicing.. it will likely be about a month before I will be at 80% on the ship, to the point that I can even think about digging the wire EDM back out to finish it.. and write another article for the magazines submissions... Cause I get paid to write articles as anybody could, I just do that first, before I release it to the public for free, I allow the magazines to get their sales up, and then I dona massive public drop.. I think the wire EDM will have to be a multi article publishing over several issues, maybe 3 to 5 months?? We'll see what we work out... But, when I do my drop, Nero, I will send the link of info to you, to flag ship and it will be totally free/open source for all benefit or the people.. and if you can capitalize off it, do so...I dont care if people make money off it, and don't care that I put it out there for free.. both machines... Let alone the other 80 projects I have done over the past 30 years...

@neverendingstudent 2 ай бұрын

From how they talked about it, I'm guessing it's basically run a sample G code (on a specific metal/alloy/conductive material with a specific wire alloy) hoping for X/Y dimensions, then do precision measurement on the end product, and you have your (initial) calibration offset values for that wire/material combination. You *would* need separate calibration runs (and probably iterative calibration to figure out your +/- manufacturing tolerance capabilities) for each material you want to cut. All other factors would have to be taken into account as well (are you recirculating your water, are you running the recirc through filtration, recirc flow rate, energy and frequency settings, etc...) to get the most accurate and repeatable results possible. Thing is, as a home wire-EDM community grows and people do this iterative testing and share it, the individual barrier to entry in time investment will drop and drop as each person need to do less and less calibration and can replace a lot of the initial calibration testing with looking up results other people have gotten when working material X.
