Part Cooling with Neopixel

Info

This is a part cooling system made by this guy along with my approach on hotend Neopixels.

You will need

• 5 Neopixels similar to this one - Single Breakout Neopixel
• a motherboard that can support Neopixels
• Soldering Iron
• a 3-wire ribbon cable with a connector to fit your motherboard
• ready to tweak some firmware stuff
• Insulation tape

Installation

• On the blower side, you screw it to your blower fan, the same way the stock blower vent is installed.
• On the other side, it holds to the fan box with a small chamfer, make sure to slide it in.
• The leds are seated into their slots and then soldered with small wires . You can even hot-epoxy glue them to the printed but, but this makes it impossible to transfer them to a new print.
• Cover the wires with some insulation tape. The fan box is metal and could short your leds.
• If you are using Skr e3 mini you have to change a small jumper on the motherboard to power the leds. Here is the SKR documentation that shows the jumper.

Firmware

• I am using marlin and i had to enable neopixels and flash again
• If you are using an SKR mini e3, you can follow this github solution to get the leds working. This solution implements this improved Neopixel library
