Hi All,

At first I was plugging the fan directly to my power supply, but recently decided to connect it to one of my controlled power outputs.

In Sprinter I added the code to enable it at all times, since I never saw the fan coming ON or OFF with jobs. I do see G Codes 106 (ON) and 107 (OFF) on Sprinter. Should I assume Replicator G does not utilize these G Codes? Does any SW does in fact coordinates fan actuation? Or is this something I need to enable somewhere on the slicer SW? Thanks!

Well, look at the G-code. You can view it in a text editor.

Slic3r controls the fan in 'Cooling' section of the 'Filament setting' tab. I don't use Replicator G, but I would have thought is supported fan control. Check your fan works from the command line first, by trying the following from [reprap.org]

M106: Fan On
Example: M106 S127
Turn on the cooling fan at half speed. Mandatory parameter 'S' declares the PWM value (0-255). M106 S0 turns the fan off.

M107: Fan Off
Deprecated. Use M106 S0 instead.
