Plug-in enables two lights per one M150 command

[professor305]

When entering the "M150" command 2 lights of the RGB lights come on. For example,

• the command "M150 R" turns green lights on as well as the requested "R" red lights,

• the command "M150 G" turns blue lights on as well as the request green lights,

• the command "M150 B" turns on red lights as well as the requested blue lights.

• the command "M150 R U B" turns all the lights off

• finally the command "M150 R0", "M150 G0", or "M150 U0" turns on all lights making it appear white

I've tried uninstalling/reinstalling the plug-in to no notable change in the actions above and have verified pin location and even moved to other GPIO pins.

Octoprint 1.4.0 LED setup 12v led strip ran thru relays All relays work fine with enclosure plug in but would have to be toggled on/off. But within this plugin, not so well.

Hi!

I'm experiencing the same issue. Have you had any luck finding a solution?

Are either or both of you using pigpiod? I hate to admit it, but OctoPrint setup is really outdated. I'll see if I can get some time later this week to get my Pi upgraded with the latest OctoPrint to reproduce.

I'm sorry if I have wasted your time, but it turns out I'm an idiot =P Before wiring a bunch of relays I wanted to try out your plugin and the LED strips powering them directly from the Pi, but it wasn't until now that I realized that the GPIO pins are not grounded to make the LED strip light up, but powered on, so of course it won't work. I'm a complete beginner when it comes to Pi's and I've never used them for anything else than Octoprint. Can the GPIO pins be connected to ground?
