So here's what I learned... The 5V in the AUX2 group of pins isn't 5V but both 5V pins in AUX1 are. I'm pulling 5V from AUX1 & still using D44 from AUX2. The 'blinky' was coming from having less than 5V. The salmon was because I had a mistake in my math. It's working fine now. I have my led function being called from within the manage_inactivity function in Marlin_main. No issues with

I'm hoping there is a public variable I can reference in code I'm adding to Marlin_main.cpp to check whether the 12V power supply is turned on or not.

Hi Dust. Thanks for the quick reply. I know this isn't the first time you've had to tell someone this. I've also posted this issue in Adafruit's forums asking if anything can be done with neopixel timing to get it to play nice. I know it's a longshot. In the meantime, given my motherboard, are D40, D42 & D44 actually available?
I found //#define TEMP_STAT_LEDS in configuration.h and

I want to use an available digital pin to control a neopixel RGB LED. Looking at the RAMPS 1.4 schematic, in the AUX2 area, I see D40, D42 & D44 may be available. Trying to decipher pins.h knowing I have motherboard 33 to be sure these are available and I can't seem to find a definitive answer. I've hooked up to D44 and didn't get expected results.
My question is, given that I have mother
