Is there a forum member willing to proof and amend where necessary, my control schematic for my self built CNC wood router?

After many many days scratching my head, trying to put together a control circuit for my SELF BUILD cnc router I have to conclude I need help.

I am not an amateur with electronics, but an advanced beginner. I am trying to put a wiring schematic together which includes at least an E Stop & Fault Trips. My CNC consists of 3, DM556T Stepper Drivers, 3 NEMA 23 Stepper Motors, a 240 vac > 36 vdc transformer, my spindle is 240 vac. I hope to be using ARDUINO UNO as controller.

Can anyone offer help and advice please.?

Regards.

Well, as you can see below I finally got around to it . . . .

I have started to put my CNC router control circuit together, and I am concerned where in the circuit I should place an E Stop.
I have noticed the my PSU (240 vac > 36 vdc) transformer, on the 36 volt side stays powered for a few seconds, my initial thought was to place the E Stop in the 240 vac line to the PSU, If I am right this will not stop the motors dead will it due to the fact that there are Capacitors on the 36 volt rails keeping them live for a few seconds, or have I got it all wrong.

Regards.
