Hi
I just read your message .
Some many years ago I contacted the firm in Italy to have the scheme of the Eldis 2.40. they did not give me any information.
So I made the electric scheme of the Eldis myself. I used Circad CAD version to made the scheme of the 6 pcb circuits also the scheme of the inter connecting of the PCB's between each other.
Hopely your EDM is working.
