I didnt think I had said anything that required being called "Goby" but never mind.

Birchy the estop input is not relying on the software to stop the machine but rather informing it that an estop has occurred but I think youve got that now.
I would still leave the pc on a seperate supply though but thats a personal opinion. I would not like a fault on the machine control side to trip the mcb and dump the pc at the same time.
