Hello from Grenoble

Doddy, are you using a secondary e-stop button to stop everything, including PSU to XYZ motors, controller, etc? This is what I am doing at the moment. I just found that the mill e-button carries the 240V mains L and N straight from the socket.

Mine now just carries the Live. I've re-purposed the second pole of the E-Stop to send a control signal back to the control electronics. I don't look at the E-Stop to provide isolation from the mains - I look at it to effectively take power from the spindle-motor - good enough for shed-ware.

EDIT: But if you had a mains relay you could slave an E-Stop signal from the returns from the E-Stop control.
