you are losing me with the modifications I cannot act that quickly (wife, 3kids and a dog all need a bit of my time) but I understand it, thank you, don't stop with the information!!
more questions,
on the large contactor to the right of rl 2/3/4 there is a red wire going in the auxiliary contact mounted on the top and an earth coming out can you see where that red is coming from, also the orange wire going in and coming out of the far right terminal, the reason for this is I need the estop and enable circuit to be right before anything else.

I don't know how many machines exist today, I contacted boxford and I am waiting for a reply I will let you know.
you are very helpful and thanks for the info,
Chris w.
