Topic: connect a fan

Hi

A quick question:

Can I connect a fan at the outlet of the LED Ligts? I need to cool down a motor that gets a little too warm.

No that is roughly 5 volts you need 12 for a fan.

Re: connect a fan

I grabbed a 12v power supply, a 3 pin extension, and a 4 way splitter from Amazon for probably $25.
I power 2 40mm fans and the 30mm fan for my E3D. Works great, simple solution.

Multiple SD2s- Bulldog XL, E3D v5/v6/Lite6, Volcano, Hobb Goblin, Titan, .9 motor, Lawsy carriages, direct Y drive, fishing line...the list goes on
Filawinder and Filastruder #1870.....worth every penny!

You sure? Schematic shows 12v on JP18 and JP19.

Filastruder - the robust, inexpensive filament extruder

Actually I am not sure on that board your info is better than mine.  I was going with error on the side of caution.
