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 buy them in a plug-in device or as a powerstrip where each socket is addressable. There are quite a few of these on the market.
Here is what I have: amazon.com/dp/B07B8W2KHZ <https://www.amazon.com/dp/B07B8W2KHZ?psc=1&ref=ppx_yo2_dt_b_product_details> Place the script to turn the power on and off in /etc/rc5.d and /etc/rc6.d and then it is done as the normal part of booting and shutdown. If you like the device you can likely find a use for half dozen of them around the house, use them like light timers with software that runs a schedule 24/7 or use them to control AC powered stuff from a phone app. On Tue, Feb 15, 2022 at 6:28 AM Thaddeus Waldner <thadw...@gmail.com> wrote: > 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 supplies. > > 3) shutting down the pi via the user interface turns off main power to all > control power supplies when finished. > > I’m considering installing one of those powered mains disconnect switches, > the likes of what you find in office photocopiers and industrial cnc > machines. > > Any ideas? > > > > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > -- Chris Albertson Redondo Beach, California _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
