Emergency relays and e-stop stop switch

ov_darkness

Hi,
I've started to build my new machine.
It will be powered from e phase circuit.
L1 - bed heater (2.4kW-3kW) via SSR
L2 - chamber heater (2kW-2.5kW) via SSR
L3 - electronics and mechanics.

What I want to do:

Have a mechanical disconnect (e-stop switch) that will allow me to stop the print in case of emergency (my burns from my accident with Zortrax M300 Plus are still healing).
I want my Duet to NOT be powered off by e-stop, but I want it to cut the power to motors and heaters.
I want my printer to enter pause (configurable) when door is opened
I want my printer not to start the job unless all doors are closed and locked.

How to configure this?
I understand that I need safety relay, e-stop switch and some macro on duet?

Can I do this on Duet 2 or should I go for Duet 3?

Provide 5V external power to the Duet. Have the E-stop switch cut power to the VIN power supply but not to the 5V PSU.

You can do that in daemon.g.
