This is the part that won’t work. The machine is small enough to pick up and
What? You have a wall outlet to power the mill. There is obviously power
in the wall output. The switch uses just a few milliwatts.
This does work. I've got several of these little switches. Of course the
computer can not use WiFi to turn itself on. You need a human to somehow
kick-start
Thanks for all the ideas.
I don’t think a WiFi solution will work because I want to completely power down
the system. There’s not too much power, as I would only need to switch the
control power; all the high power circuits need only be switched through their
respective relays.

Sweet, the perfect companion to my idea.

Those 'smart sockets' can be really handy. I use one to control the
startup of my 3 phase rotary converter. That way I can be in the shop
and only have the converter running when I need 3 phase. In the house is
a manual lockout switch for times when I know I won't need 3 phase.

How much power does your system use? If it can be powered from a normal
120 volt AC then you can buy a "Smart Outlet" that switches the 120V by
WiFi, cost about $10 or $15. The Pi then can turn off or on any AC mains
powered device. They sell these on Amazon or at Home Depot. You can

I'm almost sure I've already seen ready made modules, also with UPS
features
Perhaps this is what you're looking for?

On a small cnc machine run by a raspberry pi, I’d like to set up the main power
to accomplish the following:
1)pressing the power button/flipping the switch turns on the machine
2) pressing the off button, the pi should first perform a shutdown then turn
off the main power to all control power
