RAMPS 1.4 Board Second Extruder Losing Fan Control

Hi!

I am using a RAMPS 1.4 board and am about to add a second extruder and hotend.

Changed Number of extruders to 2, set the heat pin to the correct type, motherboard setting, everything compiles, yea!

I realize by adding a second extruder that the output I once used for fan speed control is now lost. (Pin 9)

Can I move this to one of the other aux pins and still have control?

Do I need to move this to a manual control?

Is there a different board I can use?

there are various fan extenders, just google for them,

Yes they just connect to various aux pins and the fan in attached via a mosfet

you will probably have to tweak your pins.h for auto control, depending on what pins you use.
