This is the first time that I tried out cutting some metal with my wire EDM machine and I'm really happy that the wire did not break and I could actually cut the workpiece. For me that was the best possible outcome, because my expectation also included that the wire would break as soon as it touches the workpiece and I would have to change the arc generator circuit for less power or so. But it worked out and so I can now work on optimizing the system and I can try to cut thicker, more complicated workpieces.

I also have to post more footage and details about the project to make it easy to replicate for those who would like to build their own Wire EDM Machine.
