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.

I just had some funds reserved to buy a Carvera Air, but then I didn't buy it because of the noise and space is needs (including vacuum and all the additional tools and parts that a CNC needs). This wire EDM looks like a great machine to buy and build instead. I'll probably design my own machine around the power supply.

I saw Cooper's Iron Ring and thought "with a Canadian engineer as the face of this, this should be good." And it was! I'm not quite ready to dive into this but as someone who's been interested in exploring home CNC machining for a while this is definitely a thing I want to keep an eye on.

I am about to commit blasphemy: I am more excited to see this than Voron Cascade. I ask a machine shop to make a precision gauge for me? They default to the EDM wire. I dream about CNC plasma cutter? This is far superior. Now, the question is: do I commit my ender3 to a Enderwire? Or an Ender....um, wire?

@@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.

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.

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...

FAQ: "Can the wire be reused? The wire cannot be reused immediately, as it wears out during the EDM process. However, it can be recycled."

The question: how much it cost in wire? Ex, how much to cut a 1mm thick Al or Steel plate on a straight 100mm line? For yankee: 1/32" thick on a 4" line.

Could this be used to for cncing metal not just cutting?

@neverendingstudent

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.

So, this only can cut outer surfaces? With the wire being pulled through under tension, you can't cut a hole in the center of metal, correct?
