Re: High electrode wear and instable burn with thin electrodes on my DIY EDM machine
I spent a few years as a toolmaker using standard manual and CNC EDM machines. There is a reason why fine detailed work needs more control than just your simple R/C setup. Fine work requires precise control of on and off times as well as current, voltage, frequency and polarity. If you simply want to burn out a tap then R/C will probably do. Fine high surface finish work is going to require some pain if you want to build a controller yourself. There is no way around it. It's a complex field with many variables. There are no shortcuts. Congratulations on what you have done so far. A great effort.

Maybe try using edm 244 oil instead of water? Just a suggestion. Also try and add more flushing. Discharge can build up causing erratic burning.
