Fan Codes

Quick Question. Can I turn fan2 off from GCODE commands? I would like to use it to control my LED lighting in my dust enclosure. I am using the full size Rambo 1.3

Yes, you just need to know the pin number.

Have you tried
the M106 command?
M106 [P <index> ] [S &lt;speed&gt; ] [T <secondary> ]
see full syntax here:
http://marlinfw.org/docs/gcode/M106.html
but for that to work the
#define EXTRA_FAN_SPEED
has to be activated in your configuration_adv.h
