Wow! So much easier than the previous method. So, so glad I held off and did it this way. Works a treat.

That is great to hear!

In the document it says ‘An emergency stop button with two Normally Closed terminals will be required.’ One set is connected to the Duet Controller E1 port. Is the other set of terminals used to cut power to the CNC PSU, Router or both?

Hi Peter,

Just one is needed for the above guide. But you can use two to also kill power which would make it double safe. Ryan

I tried to replace the emergency off with the HomeAll function but it doesn't work.

HomeAll is as fixed in the system as the emergency stop?
