Hi everyone,
I finally had the time last night to apply the solutions who where giving to since I started this thread except the 2 relays one because I did not have them handy. So I change to pin #2 and I used better shielded wires for the relay, I even shielded the relay itself, and the result is .......
Something works because apparently I do not have the problem anymore. I have the feeling that the shielding part was the reason but I will try to investigate more and will post my finding.
I also want to implement this 2 relays idea as a additional safety measure.
Thanks to everyone for your time and advices, hey.... you problably save my fingers at one point and my machine is ... Scarry!!!! ..... NO MORE!!!!!!
THANK YOU
