How to Wire the FlashForge Creator Pro LEDs with Klipper
You can't wire the LED strip to the SKR Mini E3 v3 or similar because the NeoPixel output only supplies 5 volts. Other boards may have 12 volt LED power, but you'd need to step that up to 24 volts with a DC-DC buck converter.
If you look up in the top front rim of the FlashForge Creator Pro, you'll see a circuit board with a bunch of surface mount LED's. They require 24 volts, so in lieu of a way to control them, I connected the 24v input directly to the power supply 24v output, and grounded the 3 other wires also on the power supply's ground. To figure out which wire is which, look at the RGBBoard in your printer and look for the 24v printed on the circuit board as shown below. Follow the wire down and connect it properly.
By grounding different combinations of wires you can make the light different colors. You can ground all three for white, which is what I did. I'm sure there's a more involved way to control the color but I haven't looked into it yet.
I plan on adding a bracket with a toggle switch to turn the light off when I'm sleeping.
