M2 v4 Extruder Headlights

Post by airscapes » Sun Apr 01, 2018 9:36 pm

Wanted more light on the part so I installed a couple of LED on the back of the bed fan. I also removed the finger guards from both fans to reduce the noise and move more air.
Parts List is:
2 NTE30045 White LEDs (local Micro center)
1 560 ohm resistor
Arduino male and female headers 2 pins worth of each
hookup wire, shrink tubing, wire ties
Attached SLTs of LED brackets, LED covers, 3mm Spacer

Both Fans are 24v on my M2 so resistor is for 24v, if you have 12v that would need to change, check online-calc for proper resistance. http://ledz.com/?p=zz.led.resistor.calculator

LEDs are wired in series with the resistor is first in line before the LED. Feed will be coming from the extruder fan leads. The white wire connects the negative lead of the first LED to the positive of the second.

To tap into the extruder fan lead I wanted a removable connector should I need to replace that fan so I made one with the Arduino headers. Liquid electrical tape was used to insulate and give strength to the connector.
