@Mike_Thornbury It is wireless in the sense that I run it off the Raspberry Pi (+OctoPrint) primarily but I don’t yet have the Ad Hoc hotspot functionality set up for that when I’m away from my home network (my Edimax WiFi adapter is giving me fits).
@John_Davis no, I was thinking more of driving your controller directly via Bluetooth. But then, I had ignored the Pi/Octoprint angle, so of course you have Wifi.
