Request: Turn on PSU when pressing "connect"
Along the lines "connect after turning on PSU" and "turn on when starting print" perhaps a feature that automatically turns on the PSU when the Connect button is pressed, with a settable delay to attempt the connection.
I get the request in general but could you elaborate the exact use case here?
It's just a non-critical step saver. Rather than having to hit the toggle then hit "connect to printer", one could click "connect to printer" and it would automatically toggle on the printer the attempt a connect after a brief delay. (or the power toggle could attempt the same)
Yes but what is the use case here? Let me clarify, how do you have everything wired and set up? What steps does everything go through? Is your printer using USB serial? etc...
MP Select Mini which is USB Serial, I have the Pi a relay housed inside cutting the DC to the printer. Currently setup as NO, but I'm debating switching it to it to NC so if/when I reboot the pi or restart octoprint it won't cut power to the printer. The power switch is wired ahead of the relay and can cut power if necessary.

This would be incredibly useful for me as well. My setup is a TAZ6 which runs a RAMBo board. I have a relay setup controlling power to the TAZ6. Unfortunately auto connect via PortLister does not work in this scenario. The chip running serial to USB on the Rambo board is powered via USB so the serial port is preset always while that USB cable is plugged in even though power is cut to the RAMBo board.
Would be very useful for me too! I have the Pi connected to +5VSB and the controller card connected via USB, but it doesn't power from usb, so it is powered from 12v. It doesnt have the option to power both from usb and DC, only selectable via jumper (Anycubic Trigorilla).
So clicking the connect button to turn on psu and connect would definitely save a step!
+1 for the "connect after turning on PSU". I use octopi (always on) with an anycubic i3 mega on USB and it always require a manual "connect" click after switching on the PSU of the printer. Would be great to save that step, otherwise the "Automatically turn PSU ON" is rather useless because one always has to click connect to start the print
you need to look at portlister plugin. that is exactly what it does. it will connect to the printer controler when it senses that there is a response from the USB connection when the controller comes online.
https://plugins.octoprint.org/plugins/portlister/
you have to give a moment for portlister to find it. you don't want the watchdog to run constantly so there is some latency. if you can not be patient for the watchdog cycle to complete, then you can connect it manually. its like every 20 seconds by default.
if your controller card is 5V powered, ie powered by USB from the raspi, then the controller is always on and all PSU control needs to do is trigger the relay controlling the 12V psu. if you trigger any of the psu on gcodes, then it will come on.
Just download and use the Pull. That's what I've been doing and the auto connect printer option works perfect. If the creator of the plugin is unwilling to merge the Pull into the master then we'll just have to download and use the Pull. Just go to the Pull Request tab and it's the first or second one. Pull #101
Pull #101 seems to work perfectly for my use case, which sounds identical to @jbkuma's.
