That's super tidy, I see you went DC in the end. What voltage output transformer is it? 50v?

I wired the transformer to a 13 amp light style switch and then my VFD and water pump to another switch and both of them are wired from the emergency stop.

This way I can easily turn the transformer on/off and if the vfd is powered the water pump is on. I have both switches and the emergency stop at the front of the machine for easy access in a row.

If I hit the emergency stop it kills power to both the steppers and the vfd, I still have to work out how to get it to trigger an estop on the pc but it's good enough for me at the moment.
