Geeetech Reprap Ramps14 Rrd Fan Extender For 3D Printer With 2 Channels

Description : - If you build or upgrade your printer with/to DUAL-EXTRUSION (2 extruders) including a heated bed all the output ports (D8, D9, D10) will be used. In this case, there is no option to connect a firmware controlled FAN to RAMPS board directly. However, in Sprinter/Marlin firmware there is an option already (Marlin : BOARD 34) which redirects the FAN to RAMPS output D4. But this solution needs a buffer/driver in order to work. - The RRD-FAN-EXTENDER is exactly what you need in this case. It is a plug and plays solution to mount the FAN for DUAL-EXTRUSION setups with RAMPS1.4. But instead of adding only one additional output port the RRD-FAN-EXTENDER is equipped with 2 PWM controllable channels(D6/D11). The second channel can be used for another fan(e.g. to cool the stepper driver) or for adding light control (e.g. add dimmable LED light to your machine).
