How to Cut Nearly Any Metal on your 3D Printer

For the past few months I have been working on a way to cut nearly any metal using electrochemistry. Electrochemical maching allows you to mill/engrave steel, aluminium, and many other materials without overhauling your printer, using an expensive spindle, or spending thousands on a dedicated CNC machine.

So far I have been able to cut right through steel about a mm using an hour and 300 mA of current. The only thing holding me back from slicing right through flat stock is the software I am using (inkscape).
