Hi C4beard,
Check the pcb tracks between relay and green plug

Hi thanks for getting back to me i checked the traces on the board and all seems ok but still not turning the router on. If i power the router direct to 240v it works so has to be an issue with the cnc shield

Hello,
Can you do a continuity check on the contact of the relay ?
Unplug the router (there must be no 230V around), and use a multimeter to check if the contact is opened/closed right under the shield when you switch off/on the router on the tft.
Probably the relay is defective.

Ok now relay has been replaced and all is well thanks for the advice
Re: Cnc shield issue
Thanks for the feedback.
It would be interesting if you can tear down the relay to look the failure and maybe you could explain what happened.
