I am back with an update,
Figured it is not smart to do feed hold, but decided to go with E stop.
So i did some adjustment to the electronics, set it up in a way that light curtain is always active, however only when machine is working is E stop in play,
the way i did it is, used one of the outputs from BOB to activate AND part of the solution.
Used Flood relay to activate AND part and adjusted PP accordingly.
Problem i have now is, when E stop is activated, it turns off MIST/FLOD relays, is it possible to prevent this in any way?
Basically is it possible, to set up program when E stop is activated one of the outputs remains in a last state: if off than off; if on than on;
I did some googleing, and found someone asking the same question, but when i use the link, it redirects me to index page of the forum
Any help would be greatly appreciated, thanks in advance
Also when it is ready, i will post the video of machine working, not too many STUD welders in video section.
