I bought LED strip wiring and am currently using just a 110 plug, is there a way to wire it up to rumba or power supply directly instead?
yes, I have my LEDS wired straight to the PSU. Or you can take 12v from the Rumba board and I think there's a way to turn LEDs on and off using gcode or a octoprint plugin.
Mine is powered off the main PSU without any problems (I have 4 strips). I ran a wire up the back wire stack and each of the 4 strips takes a lead off that so if one fails (had it happen) the others are in parallel.
