Just a quick note, I stumbled on the "pson" reference on IO4. I have not heard of this before so I dug around and found I can do exactly what I am trying to do by enabling the pson in the config file and now I have an on/off switch that is in the web interface. I can also control it via. M80 and M81 .
I am not declaring it a total victory yet, because I don't know if that snafus up something else in the process. But so far so good. Now I just have to figure out a way to incorporate it into my pre and post in my slicer when the time comes. I also want to make sure I have it working during filament changes/ hotend temps, etc.
Just thought it may help someone else as well.
Cheers,
Gumby
