So far wire EDM was the main focus of all the latest updates and changes. Nobody had a need for sinker/ram EDM and even if the code still supports sinker mode it was not really well tested or maintained.

The default settings are specialized for wire EDM and provide a heavy burn for rapid cuts. But this seems to be an issue with sinker electrodes. The wear seems to be too high and I assume that it is related to the aggressive burn at high frequency.

In order to provide sinker settings and maybe even change the sinker code I need a sinker.

It is a work in progress and may take some time to finish.

Both machines can be operated with the same control unit. XY to the wire router and Z to the sinker tower.
